The aircraft movable range information is information regarding the movable range of the predetermined portion of the aircraft 3', and specifically, how much the predetermined portion of the aircraft 3'is from the initial state during the operation of the aircraft 3'. It is information that identifies whether it works. The processing unit 11 sets the movable range of the aircraft model 3 based on the aircraft movable range information, and specifically, sets how and how the aircraft model 3 moves from the initial state SS. In the example of FIG. 5, in the machine body movable information, the rotating portion 32 is rotated by a predetermined angle from the initial state SS around the rotation axis 3c in the circumferential direction (clockwise in FIG. 5) by a predetermined angle (broken line in FIG. 5). After that, it is specified that the rotation axis 3c is rotated in the other side in the circumferential direction (counterclockwise in FIG. 5) by a predetermined angle to return to the initial state SS.

In the present specification, for convenience, the state of the simulation model M when the simulation model M moves to the maximum from the initial state SS is referred to as "maximum degree state SM", and the simulation when the movement of the simulation model M ends. The state of the model M is called "final state SF". The maximum degree state SM of the simulation model M corresponds to the states of the hose body 2'and the machine body 3'when the machine body 3'moves to the maximum from the initial state. The final state SF may be the same as the initial state SS, may be the same as the maximum state SM, or may be different from both the initial state SS and the maximum state SM. In this example, in the maximum degree state SM, the second end portion 2b of the hose body model 2 and the rotating portion 32 of the machine body model 3 are on one side in the circumferential direction around the rotation axis 3c from the initial state SS (clockwise in FIG. 5). ) Is the state of the simulation model M (broken line in FIG. 5) when rotated by a predetermined angle, and the final state SF is the maximum degree of the second end portion 2b of the hose body model 2 and the rotating portion 32 of the machine body model 3. It is the state of the simulation model M when it is rotated by a predetermined angle from the state SM to the other side in the circumferential direction (counterclockwise in FIG. 5) around the rotation axis 3c, which is the same as the initial state SS.
Further, in the present specification, for convenience, the operation of the simulation model M when the simulation model M moves from the initial state SS to the maximum degree state SM is referred to as "outward operation", and the simulation model M is finally from the maximum degree state SM. The operation of the simulation model M when moving to the state SF is called "return operation". When the final state SF is the same as the maximum state SM, the simulation model M performs only the forward operation and does not perform the return operation.

After the input step S1, as described above, in the simulation step S2, the processing unit 11 bases the simulation model M (in this example, the hose body model 2 and the machine body model 3) based on the input information input in the input step S1. ) Is used to continuously simulate the behavior of the hose body 2'during the operation of the machine body 3'.

Based on the movable range information, the state of the hose body model 2 (the orientation of the metal fittings 221, 222, the shape of the hose 21, etc.) at each predetermined time after the initial state SS is calculated.
When the machine model 3 moves as in this example, the machine model 3 may be made to move according to the machine information in the input information during the simulation (in that case, the processing unit 11 behaves as the machine model 3). , Or the processing unit 11 may simulate the behavior of the machine model 3 based on the machine information.

After the simulation step S2, in the determination step S3, the processing unit 11 performs a determination process based on the result of the simulation step S2 (and thus the simulation process). In the present embodiment, the processing unit 11 makes a twist determination in the determination process. In the twist determination, the processing unit 11 determines whether or not there is an abnormality based on whether or not the predetermined hose body portion of the hose body 2'is excessively twisted. In this example, the predetermined hose body portion is the second end portion 2b'of the hose body 2'. When the processing unit 11 determines that the predetermined hose body portion of the hose body 2'is excessively twisted, it is determined that there is an abnormality, and on the other hand, it is determined that the predetermined hose body portion of the hose body 2'is not excessively twisted. If so, it is judged that there is no abnormality.
As the predetermined hose body part to be determined for twisting, even if it is a part or all of the metal fitting 221'or 222' (in this example, the end portion 2b'of the second metal fitting 222') as in this example. It may be a part or all of the hose portion 21, or it may be the whole of the hose body 2. If the metal fitting 221'or 222'is excessively twisted, the connection between the metal fitting 221'or 222'and the machine body 3'may be loosened, and thus fluid leakage may occur. When the predetermined hose body portion to be determined for twisting is a part or all of the metal fittings 221'or 222' (in this example, the end portion 2b of the second metal fittings 222') as in this example, the machine 4 It is possible to avoid attaching the hose body 2'to the machine body 3', which causes loosening of the connection between the metal fitting 221' or 222' and the machine body 3'during the use of the hose body 2'. Further, if the hose 21'is excessively twisted, the hose 21'may be damaged. When the predetermined hose body part to be determined for twisting is a part or all of the hose part 21, the hose body 2'has a body 3'that causes damage to the hose 21'during the use of the machine 4'. It is possible to avoid mounting on the hose.

Here, the processing unit 11 determines the twist, and based on the result of the simulation processing, at any time during the operation of the machine body 3', the above-mentioned predetermined hose body portion of the hose body 2'(in this example, the second). A torque determination may be made to determine whether or not the predetermined hose body portion is excessively twisted based on whether or not the torque at the end portion 2b') exceeds the predetermined torque threshold value.
The torque may be defined to be positive (+) or negative (−) depending on the direction, or may be defined to be always positive (+) regardless of the direction. In the former case, in the comparison with the predetermined torque threshold value, the absolute value of the torque and the predetermined torque threshold value shall be compared.
This will be described with reference to FIG. In the graph of FIG. 6, the solid line indicates the predetermined hose body model portion (in this example, the second end portion) corresponding to the predetermined hose body portion of the hose body model 2 in the simulation using the simulation model M of the example of FIG. The torque (exponential value) acting on 2b) is shown. In the graph of FIG. 6, the horizontal axis is the time (seconds) during operation of the simulation model M, and the vertical axis is the predetermined hose body model portion (specifically, the second end portion 2b) of the hose body model 2. ) Is the torque (exponential value) acting on. In the example of FIG. 6, the torque is defined to be positive (+) or negative (−) depending on the orientation. As described above, the processing unit 11 is attached to the predetermined hose body model portion of the hose body model 2 at each time of each predetermined time during the operation of the simulation model M in the simulation of the simulation step S2 (and by extension, the operation of the machine body 3'). Calculate the acting torque (exponential value) respectively. The calculation of this torque may be performed in the simulation step S2 or in the determination step S3. Then, in the torque determination in the determination step S3, the processing unit 11 determines the torque (specifically, in this example, the absolute value of the torque) and the predetermined torque threshold value Tt (specifically, in this example) at each time during the operation of the simulation model M. When it is determined that the torque in the predetermined hose body model portion of the hose body model 2 exceeds the predetermined torque threshold Tt at any time during the operation of the simulation model M as a result of comparison with 6). At any time during the operation of the machine 3', it is determined that the predetermined hose model part and thus the predetermined hose body part are excessively twisted, while in other cases, any of the parts during the operation of the machine 3'. Even at the time, it is determined that the predetermined hose body model portion and thus the predetermined hose body portion were not excessively twisted.
When the predetermined hose body portion to be torque-determined is not a single point but a portion having a width (for example, the entire hose body 2'), the processing unit 11 operates the simulation model M. Torque acting at each position at predetermined intervals along the extending direction of the predetermined hose body model portion of the hose body model 2 at each predetermined time in the middle (and by extension, during the operation of the machine body 3'). (Exponential value) is calculated respectively. Then, in the torque determination in the determination step S3, the torque at each position of the predetermined hose body model portion at each time during the operation of the simulation model M is compared with the predetermined torque threshold Tt, and as a result, the simulation model is obtained. When it is determined that the torque in at least a part of the predetermined hose body model portion of the hose body model 2 exceeds the predetermined torque threshold Tt at any time during the operation of M, any of the time during the operation of the machine body 3'. At that time, it is determined that the predetermined hose body model part and thus the predetermined hose body part are excessively twisted, while in other cases, at any time during the operation of the machine 3', the predetermined hose body It is judged that the model part and the predetermined hose body part are not excessively twisted.
In the waveform of the solid line in FIG. 6, the absolute value of the torque of the predetermined hose body model portion (second end portion 2b) exceeds the predetermined torque threshold value Tt at a plurality of times during the operation of the simulation model M. Therefore, in the torque determination, in the simulation using the simulation model M of FIG. 5, the processing unit 11 has the predetermined hose body model portion (second end portion 2b) and thus at the plurality of times during the operation of the machine body 3'. It is determined that the predetermined hose body portion (second end portion 2b') is excessively twisted. Therefore, it can be seen that the mounting structure (FIG. 4) of the hose body 2'corresponding to the simulation model M in the example of FIG. 5 to the machine body 3'is not appropriate.

Alternatively, the processing unit 11 determines the twist, and based on the result of the simulation processing, at any time during the operation of the machine 3', the predetermined hose body portion of the hose body 2'(in this example, the second end). A twist amount determination may be made to determine whether or not the predetermined hose body portion is excessively twisted based on whether or not the twist amount in the portion 2b') exceeds the predetermined twist amount threshold.
The twist amount may be defined to be positive (+) or negative (−) depending on the direction, or may be defined to always be positive (+) regardless of the direction. In the former case, in the comparison with the predetermined twist amount threshold value, the absolute value of the twist amount and the predetermined twist amount threshold value shall be compared.
In this case, the processing unit 11 corresponds to the predetermined hose body portion of the hose body model 2 at each time of each predetermined time during the operation of the simulation model M in the simulation of the simulation step S2 (and by extension, the operation of the machine body 3'). The amount of twist acting on the predetermined hose body model portion (in this example, the second end portion 2b) is calculated. The calculation of the twist amount may be performed in the simulation step S2 or in the determination step S3. Then, in the twist amount determination in the determination step S3, the processing unit 11 compares the twist amount at each time during the operation of the simulation model M with the predetermined twist amount threshold, and as a result, the simulation model M is in operation. When it is determined that the twist amount in the predetermined hose body model portion of the hose body model 2 exceeds the predetermined twist amount threshold value at any time in the above-mentioned predetermined time, at any time during the operation of the machine body 3'. It is determined that the hose body model part and thus the predetermined hose body part are excessively twisted, while in other cases, the predetermined hose body model part and thus the predetermined hose body even at any time during the operation of the machine body 3'. Judge that the part was not twisted excessively.
When the predetermined hose body portion to be determined for the twist amount is not one point but a portion having a width (for example, the entire hose body 2'), the processing unit 11 is the simulation model M. Twist acting at each position at predetermined intervals along the extending direction of the predetermined hose body model portion of the hose body model 2 at each predetermined time during operation (and by extension, during operation of the machine body 3'). Calculate the amount (exponential value) respectively. Then, in the determination of the twist amount in the determination step S3, the twist amount at each position of the predetermined hose body model portion at each time during the operation of the simulation model M is compared with the predetermined twist amount threshold, and as a result, the result is as follows. When it is determined that the twist amount in at least a part of the predetermined hose body model portion of the hose body model 2 exceeds the predetermined twist amount threshold at any time during the operation of the simulation model M, the operation of the machine body 3'is performed. It is determined that the predetermined hose body model part and thus the predetermined hose body part are excessively twisted at any time in the above, while in other cases, at any time during the operation of the machine 3', the above is described. It is determined that the predetermined hose body model portion and thus the predetermined hose body portion are not excessively twisted.

Alternatively, the processing unit 11 determines the twist, and based on the result of the simulation processing, at any time during the operation of the machine body 3', the predetermined hose body portion of the hose body 2'(in this example, the second end). Rotation that determines whether or not the predetermined hose body portion is excessively twisted based on whether or not the rotation angle of the hose body 2'around the central axis in the portion 2b') exceeds the predetermined rotation angle threshold value. You may judge the angle.
The rotation angle may be defined to be positive (+) or negative (−) depending on the orientation, or may be defined to be always positive (+) regardless of the orientation. In the former case, in the comparison with the predetermined rotation angle threshold value, the absolute value of the rotation angle and the predetermined rotation angle threshold value shall be compared.
In this case, the processing unit 11 corresponds to the predetermined hose body portion of the hose body model 2 at each time of each predetermined time during the operation of the simulation model M in the simulation of the simulation step S2 (and by extension, the operation of the machine body 3'). The rotation angle around the central axis of the hose body model 2 acting on the predetermined hose body model portion (in this example, the second end portion 2b) is calculated. The calculation of the rotation angle may be performed in the simulation step S2 or in the determination step S3. Then, in the rotation angle determination in the determination step S3, the processing unit 11 compares the rotation angle at each time during the operation of the simulation model M with the predetermined rotation angle threshold value, and as a result, the simulation model M is in operation. When it is determined that the rotation angle of the hose body model 2 in the predetermined hose body model portion exceeds the predetermined rotation angle threshold value at any time in the above-mentioned predetermined time, at any time during the operation of the machine body 3'. It is determined that the hose body model part and thus the predetermined hose body part are excessively twisted, while in other cases, the predetermined hose body model part and thus the predetermined hose body part are performed at any time during the operation of the machine body 3'. Judges that it was not twisted excessively.
When the predetermined hose body portion to be determined for the rotation angle is not one point but a portion having a width (for example, the entire hose body 2'), the processing unit 11 is the simulation model M. Rotation that acts at each position at predetermined intervals along the extending direction of the predetermined hose body model portion of the hose body model 2 at each predetermined time during operation (and by extension, during operation of the aircraft 3'). Calculate the angles (exponential values) respectively. Then, in the rotation angle determination in the determination step S3, the rotation angle at each position of the predetermined hose body model portion at each time during the operation of the simulation model M is compared with the predetermined rotation angle threshold, and as a result, the result is obtained. When it is determined that the rotation angle of at least a part of the predetermined hose body model portion of the hose body model 2 exceeds the predetermined rotation angle threshold at any time during the operation of the simulation model M, the operation of the machine body 3'is performed. It is determined that the predetermined hose body model part and thus the predetermined hose body part are excessively twisted at any time in the above, while in other cases, at any time during the operation of the machine 3', the above is described. It is determined that the predetermined hose body model portion and thus the predetermined hose body portion are not excessively twisted.

In the twist determination, the processing unit 11 may make any plurality of determinations among the above-mentioned torque determination, twist amount determination, and rotation angle determination. In that case, the processing unit 11 determines that there is an abnormality when it is determined in each of the plurality of determinations that the predetermined hose body portion is excessively twisted, and in other cases, it is determined that there is no abnormality. You may. Alternatively, in the twist determination, the processing unit 11 determines that there is an abnormality when it is determined that the predetermined hose body portion is excessively twisted in at least one of the plurality of determinations, and in other cases, there is no abnormality. You may judge that.

In the post-determination processing step S4, the processing unit 11 performs various processes based on the result of the determination step S3 (and thus the determination process) after the determination step S3 (and thus the determination process).

For example, when the processing unit 11 determines that there is an abnormality in the determination step S3 (and by extension, the determination process), the alarm output step (alarm output process) causes the output unit 14 (FIG. 1) to output an alarm in the post-determination processing step S4. ) May be performed. In the alarm output process, the processing unit 11 may, for example, display the alarm on the display unit 141 (FIG. 1) and / or may have the audio output unit output the alarm by voice and /. Alternatively, the printing unit may print the alarm.
According to the alarm output process, the user can know that the hose body 2'that is the target of the simulation in the simulation step S2 is not properly attached to the machine body 3', and thus avoids such attachment. be able to.

When the processing unit 11 determines that there is an abnormality in the determination step S3 (and by extension, the determination process), the hose body attachment information (for example, hose body initial position information, hose body initial orientation information, hose rigidity information) is determined in the post-determination processing step S4. , Hose dimension information, and at least a part of the metal fitting information), the hose body mounting information change step (and thus the hose body mounting information change processing) may be performed. Then, the processing unit 11 includes the hose body attachment information changed in the hose body attachment information change step (and by extension, the hose body attachment information change process) after the hose body attachment information change step (and by extension, the hose body attachment information change process). Based on the input information, the simulation step S2 (and by extension, the simulation process) is performed again. Here, among the input information, the information other than the hose body mounting information changed in the hose body mounting information change step (and by extension, the hose body mounting information change process) is used in the previous simulation step S2 (and by extension, the simulation process). Use the same information that you received.
In this way, each time it is determined that there is an abnormality in the determination step S3, the hose body mounting information is changed and the simulation is performed again, so that the simulation can be repeated until it is determined that there is no abnormality in the determination step S3. , It is possible to find the attachment of the hose body 2'to the machine body 3'that does not have any abnormality. Therefore, it is possible to more effectively support the proper attachment of the hose body 2'to the machine body 3'.
In the hose body mounting information change process, the processing unit 11 includes information other than the hose body initial position information (for example, hose body initial orientation information, hose rigidity information, hose dimension information, and metal fitting information) among the hose body mounting information. It is preferable to change at least a part of them). This is because it may be difficult to actually change the positions of both ends 2a and 2b of the hose body 2'.

Note that FIG. 7 shows the hose body mounting information input to the simulation model M of the example of FIG. 5 in the input step S1 (and thus the input processing) through the hose body mounting information change step (and thus the hose body mounting information change processing). The image of the simulation model M in which the hose body mounting information different from that of the above is input is shown. The simulation model M of the example of FIG. 7 has the orientation of the second end 2b of the hose body model 2 set by the initial orientation information of the hose body and the hose length of the hose dimension information with respect to the simulation model M of the example of FIG. Only the length of the hose portion 21 set by the information and the lengths of the metal fittings 221 and 222 set by the metal fitting dimension information of the metal fitting information are different. FIG. 8 shows an image of the mounting structure of the hose body 2'to the machine body 3', which corresponds to the simulation model M of the example of FIG. 7. In the graph of FIG. 6, the broken line indicates the predetermined hose body model portion corresponding to the predetermined hose body portion of the hose body model 2 in the simulation using the simulation model M of the example of FIG. 7 (in this example, the second end portion). The torque (exponential value) acting on 2b) is shown. The torque shown by the broken line in FIG. 6 is equal to or less than the predetermined torque threshold Tt at all times during the operation of the simulation model M, and the hose body 2'corresponding to the simulation model M in the example of FIG. 7 is attached to the machine body 3'. It can be seen that the structure (FIG. 8) is appropriate.

When the processing unit 11 determines that there is no abnormality in the determination step S3 (and by extension, the determination process), the processing unit 11 outputs the hose body mounting information used in the simulation step S2 (and thus the simulation process) to the output unit 14 in the post-determination processing step S4. The hose body mounting information output step (and thus the hose body mounting information output processing) may be performed. In the hose body mounting information output processing, the processing unit 11 may display the hose body mounting information on the display unit 141 (FIG. 1), and / or may display the hose body mounting information on the voice output unit by voice. It may be output, and / or the hose body mounting information may be printed on the printing unit.

In this example, the simulation model M shown in FIG. 9A is constructed by inputting the input information in the input step S1 (and by extension, the input process). In FIG. 9A, the simulation model M is in the initial state SS. In this example, the simulation model M has a plurality of hose body models 2 that imitate each of the plurality of hose bodies 2', and a machine body model 3 that imitates a part of the machine body 3'.

The input information input in the input step S1 is at least the hose body attachment information of each of the plurality of hose bodies 2'and the respective end portions 2a and 2b of the plurality of hose bodies 2'in operation of the machine body 3'. Includes hose body movable range information regarding the movable range of. When the simulation model M includes the machine model 3 as in this example, the input information input in the input step S1 further includes the machine information.
In this example, the airframe information does not include the airframe movable range information, that is, the airframe model 3 is fixed without moving. The airframe model 3 has a cylindrical shape. However, the airframe information may include the airframe movable range information, that is, the airframe model 3 may be set to move. Alternatively, the input information may not include the aircraft information, that is, the simulation model M may not include the aircraft model 3.
In the examples of FIGS. 9 to 10, the hose body movable range information is fixed so that the second end portion 2b of each hose body model 2 does not move, and the first end portion 2a of each hose body model 2 is integrated with each other. Then, from the initial state SS (FIG. 9 (a)), the rotation is performed by a predetermined angle on one side in the circumferential direction (clockwise in FIGS. 9 to 10) around the rotation axis 3c (FIG. 9 (b), FIG. 10 (a), FIG. 10 (b)), the maximum degree state SM (FIG. 10 (b)), and then they are integrated with each other and are on the other side in the circumferential direction around the rotation axis 3c (in FIGS. 9 to 10). It is specified that the rotation is performed by a predetermined angle (counterclockwise) (FIGS. 10 (a), 9 (b), and 9 (a)) to obtain the same final state SF as the initial state SS. The rotation axis 3c is a cylindrical central axis formed by the machine model 3.

In the simulation step S2 (and by extension, the simulation process), the processing unit 11 has a plurality of hose bodies that imitate the simulation model M (in this example, the plurality of hose bodies 2', respectively, based on the input information input in the input step S1. Using the model 2 and the machine model 3), the behavior of each of the plurality of hose bodies 2'during the operation of the machine 3'is continuously simulated.
In the simulation process, the processing unit 11 calculates the shape of the hose unit 21 of each hose body model 2 in the initial state SS based on the hose body attachment information in the input information, and also calculates the hose body attachment information and the hose in the input information. Based on the body movable range information, the state of each hose body model 2 (direction of metal fittings 221, 222, shape of hose 21, etc.) at each time at predetermined time after the initial state SS is calculated.
When the simulation model M includes the machine model 3 and the machine model 3 is set to move, the machine model 3 may be made to move according to the machine information in the input information during the simulation (its). In this case, the processing unit 11 does not simulate the behavior of the aircraft model 3), or the processing unit 11 may simulate the behavior of the aircraft model 3 based on the aircraft information.

In the determination step S3 (and by extension, the determination process), the processing unit 11 performs the determination process based on the result of the simulation step S2 (and by extension, the simulation process). In the present embodiment, the processing unit 11 makes a hose contact determination in the determination process. In the hose contact determination, the processing unit 11 determines whether or not there is an abnormality based on whether or not the hoses 21'of the plurality of hose bodies 2'are in contact with each other. When the processing unit 11 determines that the hoses 21'of the plurality of hose bodies 2'are in contact with each other (specifically, the hoses 21' of at least one pair of hose bodies 2'are in contact with each other), it is abnormal. On the other hand, it was determined that the hoses 21'of the plurality of hose bodies 2'were not in contact with each other (specifically, the hoses 21' of any pair of hose bodies 2'were not in contact with each other). If so, it is judged that there is no abnormality.
If the hoses 21'of the plurality of hose bodies 2'come into contact with each other, the hoses 21'may be damaged. According to the hose contact determination, it is possible to avoid attaching the hose body 2'to the machine body 3', which causes damage to the hose 21'during the use of the machine 4'.

Here, in the hose contact determination, the processing unit 11 acts between the hoses 21'of the plurality of hose bodies 2'at any time during the operation of the machine 3'based on the result of the simulation processing. A hose contact energy determination may be made in which it is determined whether or not the hoses 21'of the plurality of hose bodies 2'are in contact with each other based on whether or not the contact energy exceeds a predetermined hose contact energy threshold.
The contact energy may be defined to be "positive (+)" or "negative (-)" depending on the direction, or may always be "positive (+)" regardless of the direction. It may be defined. In the former case, in the comparison with the predetermined hose contact energy threshold value, the absolute value of the contact energy and the predetermined hose contact energy threshold value shall be compared.
In this case, the processing unit 11 follows the extending direction of the hose unit 21 of each hose body model 2 for each time at each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3'). The contact energy acting on each position at predetermined intervals is calculated. The calculation of the contact energy may be performed in the simulation step S2 or in the determination step S3. Then, in the hose contact energy determination in the determination step S3, the processing unit 11 determines the contact energy and the predetermined hose contact energy at each position of the hose unit 21 of each hose body model 2 at each time during the operation of the simulation model M. As a result of comparison with the threshold, the contact energy in at least a part of the hose portions 21 of at least one pair of hose body models 2 at any time during the operation of the simulation model M has a predetermined hose contact energy threshold. When it is determined that the energy has been exceeded, the hose portions 21 of the plurality of hose body models 2 (and thus the hoses 21'of the plurality of hose bodies 2') come into contact with each other at any time during the operation of the machine body 3'. Judgment, on the other hand, in other cases, at any time during the operation of the aircraft 3', the hose portions 21 of the plurality of hose body models 2 (and by extension, the hoses 21' of the plurality of hose bodies 2'). Judges that they did not contact.
The predetermined hose contact energy threshold may be set to 0 or may be set to a value greater than 0.

Alternatively, in the hose contact determination, the processing unit 11 acts between the hoses 21'of the plurality of hose bodies 2'at any time during the operation of the machine 3'based on the result of the simulation processing. A hose contact pressure determination may be made to determine whether or not the pressure exceeds a predetermined hose contact pressure threshold.
The contact pressure may be defined to be "positive (+)" or "negative (-)" depending on the direction, or may always be "positive (+)" regardless of the direction. It may be defined. In the former case, in the comparison with the predetermined hose contact pressure threshold value, the absolute value of the contact pressure and the predetermined hose contact pressure threshold value shall be compared.
In this case, the processing unit 11 follows the extending direction of the hose unit 21 of each hose body model 2 for each time at each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3'). The contact pressure acting on each position at predetermined intervals is calculated. The calculation of the contact pressure may be performed in the simulation step S2 or in the determination step S3. Then, in the hose contact pressure determination in the determination step S3, the processing unit 11 determines the contact pressure and the predetermined hose contact pressure at each position of the hose unit 21 of each hose body model 2 at each time during the operation of the simulation model M. As a result of comparison with the threshold value, the contact pressure in at least a part of the hose portion 21 of at least one pair of hose body models 2 at any time during the operation of the simulation model M sets the predetermined hose contact pressure threshold value. When it is determined that the hose has been exceeded, the hose portions 21 of the plurality of hose body models 2 (and thus the hoses 21'of the plurality of hose bodies 2') come into contact with each other at any time during the operation of the machine body 3'. Judgment, on the other hand, in other cases, at any time during the operation of the aircraft 3', the hose portions 21 of the plurality of hose body models 2 (and by extension, the hoses 21' of the plurality of hose bodies 2') are connected to each other. Judges that they did not contact.
The predetermined hose contact pressure threshold value may be set to 0 or may be set to a value larger than 0.

Alternatively, in the hose contact determination, the processing unit 11 makes a contact acting between the hoses 21'of the plurality of hose bodies 2'at any time during the operation of the machine 3'based on the result of the simulation processing. A hose contact force determination may be made to determine whether or not the force exceeds a predetermined hose contact force threshold.
The contact force may be defined to be "positive (+)" or "negative (-)" depending on the direction, or may always be "positive (+)" regardless of the direction. It may be defined. In the former case, in the comparison with the predetermined hose contact force threshold value, the absolute value of the contact force and the predetermined hose contact force threshold value shall be compared.
In this case, the processing unit 11 follows the extending direction of the hose unit 21 of each hose body model 2 for each time of each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3'). The contact force acting on each position at predetermined intervals is calculated. The calculation of the contact force may be performed in the simulation step S2 or in the determination step S3. Then, in the hose contact determination in the determination step S3, the processing unit 11 determines the contact force and the predetermined hose contact force threshold at each position of the hose unit 21 of each hose body model 2 at each time during the operation of the simulation model M. As a result, the contact force of at least a part of the hose portions 21 of at least one pair of hose body models 2 exceeds the predetermined hose contact force threshold at any time during the operation of the simulation model M. If it is determined that the hose portions 21 of the plurality of hose body models 2 (and thus the hoses 21' of the plurality of hose bodies 2') are in contact with each other at any time during the operation of the machine body 3'. On the other hand, in other cases, the hose portions 21 of the plurality of hose body models 2 (and thus the hoses 21' of the plurality of hose bodies 2') are connected to each other at any time during the operation of the machine body 3'. Judge that they did not touch.
The predetermined hose contact force threshold may be set to 0 or may be set to a value greater than 0.

Alternatively, in the hose contact determination, the processing unit 11 determines the relative distance between the hoses 21'of the plurality of hose bodies 2'at any time during the operation of the machine 3'based on the result of the simulation processing. , The hose relative distance may be determined to determine whether or not it has become 0.
In this case, the processing unit 11 follows the extending direction of the hose unit 21 of each hose body model 2 for each time at each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3'). The relative distance between each position at each predetermined interval is calculated. The calculation of this relative distance may be performed in the simulation step S2 or in the determination step S3. Then, in the hose relative distance determination in the determination step S3, in the processing unit 11, the relative distance between the above positions of the hose units 21 of each hose body model 2 at each time during the operation of the simulation model M is 0. As a result, at any time during the operation of the simulation model M, the relative distance between at least a part of the hose portions 21 of at least one pair of hose body models 2 is determined. When it is determined that the value becomes 0, the hose portions 21 of the plurality of hose body models 2 (and thus the hoses 21'of the plurality of hose bodies 2') come into contact with each other at any time during the operation of the machine body 3'. On the other hand, in other cases, the hose portions 21 of the plurality of hose body models 2 (and by extension, the hoses 21'of the plurality of hose bodies 2') are used at any time during the operation of the machine body 3'. It is judged that they did not contact each other.

In the hose contact determination, the processing unit 11 may make any plurality of determinations among the above-mentioned hose contact energy determination, hose contact pressure determination, hose contact force determination, and hose relative distance determination. In that case, when the processing unit 11 determines in the hose contact determination that the hoses 21'of the plurality of hose bodies 2'are in contact with each other in each of the plurality of determinations, it is determined that there is an abnormality, and in other cases. In addition, it may be judged that there is no abnormality. Alternatively, when the hose contact determination determines that the hoses 21'of the plurality of hose bodies 2'are in contact with each other in at least one of the plurality of determinations, the processing unit 11 determines that there is an abnormality, and other than that. In the case of, it may be judged that there is no abnormality.

The post-judgment processing step S4 (and thus the post-judgment processing) is the same as that of the first embodiment.

When performing the alarm output step (and thus the alarm output processing) in the post-judgment processing step S4 (and thus the post-judgment processing), the processing unit 11 simulates, for example, on the display unit 141 in the simulation step S2 (and thus the simulation processing). As a result, while displaying the operation of the simulation model M, at the time when the hose portions 21 of the plurality of hose body models 2 come into contact with each other during the operation of the simulation model M, the hose portions 21 of the plurality of hose body models 2 are displayed. It may be displayed so that the parts that have come into contact with each other can be seen. For example, as shown in FIGS. 9A and 9B, the portion where the hose portions 21 of the plurality of hose body models 2 are in contact with each other has a different color from the other portions of the hose portion 21 (FIG. 9 (FIG. 9). It may be shown by a) and black) in FIG. 9 (b).
As a result, the user can specifically grasp which part of the hose 21'of the plurality of hose bodies 2'is in contact with how often. As a result, the user can take measures such as preventing damage to the frequently contacted portion of the hose 21'of the hose body 2'by covering the portion with an exterior member.

<Third embodiment of the hose body attachment support method-when determining the body contact>

In the airframe contact determination, the processing unit 11 determines whether or not there is an abnormality based on whether or not the hose 21'of the hose body 2'is in contact with the airframe 3'. When the processing unit 11 determines that the hose 21'of the hose body 2'has come into contact with the machine body 3', it determines that there is an abnormality, while the hose 21'of the hose body 2'does not come into contact with the machine body 3'. If it is judged that there is no abnormality, it is judged that there is no abnormality.
If the hose 21'of the hose body 2'comes into contact with the machine body 3', the hose 21'may be damaged. According to the airframe contact determination, it is possible to avoid attaching the hose body 2'to the airframe 3', which causes damage to the hose 21'while the machine 4'is in use.

In this case, the processing unit 11 extends the hose unit 21 of the hose body model 2 from the machine body 3'for each time of each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3'). The contact energy acting on each position at predetermined intervals along the above is calculated. The calculation of the contact energy may be performed in the simulation step S2 or in the determination step S3. Then, in the determination of the aircraft contact energy in the determination step S3, the processing unit 11 determines the contact energy and the predetermined aircraft contact energy at each position of the hose portion 21 of the hose body model 2 at each time during the operation of the simulation model M. When it is compared with the threshold value and as a result, it is determined that the contact energy in at least a part of the hose portion 21 of the hose body model 2 exceeds the predetermined machine contact energy threshold at any time during the operation of the simulation model M. In addition, it is determined that the hose 21'of the hose body 2'has come into contact with the machine body 3'at any time during the operation of the machine body 3', while in other cases, any time during the operation of the machine body 3'.

Based on whether or not the contact pressure exceeds the predetermined airframe contact pressure threshold, the airframe contact pressure determination may be made to determine whether or not the hose 21'of the airframe 2'is in contact with the airframe 3'.
The contact pressure may be defined to be "positive (+)" or "negative (-)" depending on the direction, or may always be "positive (+)" regardless of the direction. It may be defined. In the former case, in the comparison with the predetermined airframe contact pressure threshold value, the absolute value of the contact pressure and the predetermined airframe contact pressure threshold value shall be compared.
In this case, the processing unit 11 extends the hose unit 21 of the hose body model 2 from the machine body 3'for each time of each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3'). The contact pressure acting on each position at predetermined intervals along the above is calculated. The calculation of the contact pressure may be performed in the simulation step S2 or in the determination step S3. Then, in the determination of the aircraft contact pressure in the determination step S3, the processing unit 11 determines the contact pressure and the predetermined aircraft contact pressure at each position of the hose portion 21 of the hose body model 2 at each time during the operation of the simulation model M. When it is compared with the threshold value and as a result, it is determined that the contact pressure in at least a part of the hose portion 21 of the hose body model 2 exceeds the predetermined body contact pressure threshold value at any time during the operation of the simulation model M. In addition, it is determined that the hose 21'of the hose body 2'has contacted the body 3'at any time during the operation of the machine body 3', while in other cases, any time during the operation of the machine body 3'.

Alternatively, the processing unit 11 determines the contact between the hose body 2'and the hose 21'of the hose body 2'at any time during the operation of the machine body 3'based on the result of the simulation process. Based on whether or not the distance becomes 0, the hose 21'of the hose body 2'may determine whether or not the hose 21'has contacted the machine body 3', and the machine body relative distance determination may be performed.
In this case, the processing unit 11 determines each time of each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3') along the extending direction of the hose part 21 of the hose body model 2. The relative distance between each position at each interval and the aircraft model 3 is calculated. The calculation of this relative distance may be performed in the simulation step S2 or in the determination step S3. Then, in the determination of the relative distance between the aircraft in the determination step S3, the processing unit 11 determines the relative distance between each position of the hose portion 21 of the hose model 2 and the aircraft model 3 at each time during the operation of the simulation model M. It is determined whether or not the distance is 0, and as a result, at any time during the operation of the simulation model M, the relative distance between at least a part of the hose portion 21 of the hose body model 2 and the machine body model 3.

<Fourth Embodiment of Hose Body Mounting Support Method-When Bending Judgment is Made>
Next, the hose body attachment support method according to the fourth embodiment of the present invention will be described in detail with reference to FIGS. 11 to 12. In the fourth embodiment, the processing unit 11 makes a bending determination in the determination step S3 (and by extension, the determination process). The machine 4'may be, for example, a construction machine (for example, a hydraulic excavator, a wheel loader, etc.) or a factory facility (for example, an injection molding machine, a die casting machine, etc.).
In the description of the present embodiment, for convenience, the illustration of the machine 4'which is the target of the simulation in the simulation step S2 (and thus the simulation process) is omitted.

The input step S1 (and thus the input process) and the simulation step S2 (and thus the simulation process) are performed in the same manner as in the first embodiment.
FIG. 11 shows an image of how the simulation model M operates in the simulation in the simulation step S2 (and thus the simulation process) in this example. In this example, the simulation model M has only the hose body model 2 that imitates the hose body 2', and does not have the machine body model 3 that imitates a part of the machine body 3'. However, the simulation model M may have an airframe model 3.

The input information input in the input step S1 includes at least the hose body attachment information and the hose body movable range information. When the simulation model M includes the machine model 3, the input information input in the input step S1 further includes the machine information.
In the example of FIG. 11, the hose body movable range information is fixed so that the second end portion 2b of the hose body model 2 does not move, and the first end portion 2a of the hose body model 2 is the rotation axis from the initial state SS. It is specified that the rotation around 3c in one side in the circumferential direction (clockwise in FIG. 11) is performed by a predetermined angle to reach the maximum degree state SM and the final state SF. That is, in this example, the hose body model 2 performs only the forward movement and does not perform the return movement. However, the hose body model 2 may also be configured to perform a return operation.

In the simulation step S2 (and by extension, the simulation process), the processing unit 11 operates the machine body 3'using the simulation model M (in this example, the hose body model 2) based on the input information input in the input step S1. The behavior of the hose body 2'inside is continuously simulated.
In the simulation process, the processing unit 11 calculates the shape of the hose unit 21 of the hose body model 2 in the initial state SS based on the hose body attachment information in the input information, and also calculates the hose body attachment information and the hose body in the input information. Based on the movable range information, the state of the hose body model 2 (the orientation of the metal fittings 221, 222, the shape of the hose 21, etc.) at each predetermined time after the initial state SS is calculated.
When the simulation model M includes the machine model 3 and the machine model 3 is set to move, the machine model 3 may be made to move according to the machine information in the input information during the simulation (its). In this case, the processing unit 11 does not simulate the behavior of the aircraft model 3), or the processing unit 11 may simulate the behavior of the aircraft model 3 based on the aircraft information.

In the determination step S3 (and by extension, the determination process), the processing unit 11 performs the determination process based on the result of the simulation step S2 (and by extension, the simulation process). In the present embodiment, the processing unit 11 makes a bending determination in the determination process. In the bending determination, the processing unit 11 determines whether or not there is an abnormality based on whether or not the hose 21'of the hose body 2'is excessively bent. When the processing unit 11 determines that the hose 21'of the hose body 2'is excessively bent, it is determined that there is an abnormality, while when it is determined that the hose 21'of the hose body 2'is not excessively bent, the processing unit 11 determines that there is an abnormality. Judge that there is no abnormality.
If the hose 21'of the hose body 2'is bent excessively, the hose 21'may be damaged. According to the bending determination, it is possible to avoid attaching the hose body 2'to the machine body 3', which causes damage to the hose 21'during the use of the machine 4'.

Here, in the bending determination, the processing unit 11 determines the bending radius of at least a part of the hose 21'of the hose body 2'at any time during the operation of the machine 3'based on the result of the simulation processing. A bending radius determination may be made, which determines whether or not the hose 21'of the hose body 2'is excessively bent based on whether or not the bending radius threshold is exceeded.
Here, the "bending radius" of the hose 21'is the radius of curvature of the hose 21', and specifically, the bending inside (center of curvature) with respect to the central axis of the hose 21'of the outer peripheral surface of the hose 21'. The bending radius (radius of curvature) of the portion on the side) is preferable, but it may be the bending radius (radius of curvature) of the central axis of the hose 21', or the hose on the outer peripheral surface of the hose 21'. It may be the bending radius (radius of curvature) of the portion outside the bending (opposite to the center of curvature) with respect to the central axis of 21'. The same applies to the "bending radius" of the hose portion 21 of the hose body model 2. The predetermined bending radius threshold value is preferably set to a minimum bending radius predetermined by, for example, the manufacturer of the hose body 2', but may be set to a different value.
The bending radius defines the curvature when the center of curvature is on one side with respect to the hose 21'as "positive (+)", and the curvature when the center of curvature is on the other side with respect to the hose 21'is "negative (" It may be defined as "-)", or it may be defined as always "positive (+)" regardless of the position of the center of curvature. In the former case, in the comparison with the predetermined bending radius threshold value, the absolute value of the bending radius and the predetermined bending radius threshold value shall be compared.
The bending radius determination will be described with reference to FIG. In the graph of FIG. 12, each black circle is at each position at predetermined intervals along the extending direction of the hose portion 21 of the hose body model 2 in the initial state SS in the simulation using the simulation model M of the example of FIG. Shows the bending radius. In the graph of FIG. 12, each white circle is a position at a predetermined interval along the extending direction of the hose portion 21 of the hose body model 2 in the maximum degree state SM in the simulation using the simulation model M of the example of FIG. Shows the bending radius in. In the graph of FIG. 12, the horizontal axis is the distance (m) from the second end portion 2b of the hose body model 2 to the position on the hose portion 21, and the vertical axis is the bending radius (m) at the position. be. As described above, the processing unit 11 follows the extending direction of the hose unit 21 of the hose body model 2 for each time at each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3'). The bending radius at each position at each predetermined interval is calculated. The calculation of the bending radius may be performed in the simulation step S2 or in the determination step S3. Then, in the bending radius determination in the determination step S3, the processing unit 11 determines the bending radius and the predetermined bending radius threshold Tr at each position of the hose portion 21 of the hose body model 2 at each time during the operation of the simulation model M. As a result of comparison with (FIG. 12), it is determined that the bending radius of at least a part of the hose portion 21 of the hose body model 2 is below the predetermined bending radius threshold Tr at any time during the operation of the simulation model M. In this case, it is determined that the hose portions 21 of the plurality of hose body models 2 (and thus the hose 21'of the hose body 2') are excessively bent at any time during the operation of the machine body 3', while other than that. In this case, it is determined that the hose portions 21 (and thus the hose 21'of the hose body 2') of the plurality of hose body models 2 did not bend excessively at any time during the operation of the machine body 3'.

Alternatively, in the bending determination, the processing unit 11 determines that the curvature of at least a part of the hose 21'of the hose body 2'is a predetermined curvature threshold at any time during the operation of the machine 3'based on the result of the simulation processing. A curvature determination may be made to determine whether or not the hose 21'of the hose body 2'is excessively bent based on whether or not the hose body 2'exceeds.
Here, the "curvature" of the hose 21'is preferably the curvature of the portion of the outer peripheral surface of the hose 21'on the bending inner side (curvature center side) with respect to the central axis of the hose 21', but the hose It may be the curvature of the central axis of 21', or the curvature of the outer peripheral surface of the hose 21'that is bent outside (opposite the center of curvature) with respect to the central axis of the hose 21'. May be good. The same applies to the "curvature" of the hose portion 21 of the hose body model 2. The predetermined curvature threshold value is preferably set to a curvature converted from the minimum bending radius predetermined by, for example, the manufacturer of the hose body 2', but may be set to a different value.
For the above curvature, the curvature when the center of curvature is on one side with respect to the hose 21'is defined as "positive (+)", and the curvature when the center of curvature is on the other side with respect to the hose 21'is "negative (-)". ) ”, Or it may be defined to always be“ positive (+) ”regardless of the position of the center of curvature. In the former case, in the comparison with the predetermined curvature threshold value, the absolute value of the curvature and the predetermined curvature threshold value shall be compared.
In this case, the processing unit 11 determines each time of each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3') along the extending direction of the hose part 21 of the hose body model 2. The curvature at each position for each interval is calculated. The calculation of the curvature may be performed in the simulation step S2 or in the determination step S3. Then, in the curvature determination in the determination step S3, the processing unit 11 compares the curvature at each position of the hose unit 21 of the hose body model 2 at each time during the operation of the simulation model M with the predetermined curvature threshold value. As a result, when it is determined that the curvature of at least a part of the hose portion 21 of the hose body model 2 exceeds a predetermined curvature threshold at any time during the operation of the simulation model M, the hose body 3'is in operation. At any time, it is determined that the hose portions 21 of the plurality of hose body models 2 (and thus the hose 21'of the hose body 2') are excessively bent, while in other cases, during the operation of the machine body 3'. At any time, it is determined that the hose portions 21 (and thus the hose 21'of the hose body 2') of the plurality of hose body models 2 are not excessively bent.

The processing unit 11 may make both the above-mentioned bending radius determination and curvature determination in the bending determination. In that case, the processing unit 11 determines that there is an abnormality when it is determined that the hose 21'of the hose body 2'is excessively bent in both of the determinations, and in other cases, it is determined that there is no abnormality. You may judge. Alternatively, when the processing unit 11 determines in the bending determination that the hose 21'of the hose body 2'is excessively bent in at least one of the two determinations, it is determined that there is an abnormality, and in other cases, it is determined that there is an abnormality. It may be judged that there is no abnormality.

The post-judgment processing step S4 (and thus the post-judgment processing) is the same as that of the first embodiment.

<Fifth Embodiment of hose body attachment support method-when making a reversal judgment>
Next, the hose body attachment support method according to the fifth embodiment of the present invention will be described in detail with reference to FIGS. 13 to 14. In the fifth embodiment, the processing unit 11 makes a reversal determination in the determination step S3 (and by extension, the determination process). The machine 4'may be, for example, a construction machine (for example, a hydraulic excavator, a wheel loader, etc.) or a factory facility (for example, an injection molding machine, a die casting machine, etc.).
In the description of the present embodiment, for convenience, the illustration of the machine 4'which is the target of the simulation in the simulation step S2 (and thus the simulation process) is omitted.

The input step S1 (and thus the input process) and the simulation step S2 (and thus the simulation process) are performed in the same manner as in the first embodiment.
13 to 14 show an image of how the simulation model M operates in the simulation in the simulation step S2 (and thus the simulation process) in this example. In this example, the simulation model M has a hose body model 2 that imitates the hose body 2'and a machine body model 3 that imitates a part of the machine body 3'. The airframe model 3 has a cylindrical shape. However, the simulation model M does not have to have the aircraft model 3.

The input information input in the input step S1 includes at least the hose body attachment information and the hose body movable range information. When the simulation model M includes the machine model 3 as in this example, the input information input in the input step S1 further includes the machine information.
In the examples of FIGS. 13 to 14, the hose body movable range information is fixed so that the second end portion 2b of the hose body model 2 does not move, and the first end portion 2a of the hose body model 2 is in the initial state SS ( From FIG. 13), the rotation axis 3c is rotated in one side in the circumferential direction (counterclockwise in FIGS. 13 to 14) by a predetermined angle to reach the maximum degree state SM (FIGS. 13 to 14), and then the rotation axis. It is specified that the rotation around 3c in the other side in the circumferential direction (clockwise in FIGS. 13 to 14) by a predetermined angle results in the same final state SF as the initial state SS.

In the simulation step S2 (and by extension, the simulation process), the processing unit 11 uses the simulation model M (in this example, the hose body model 2 and the machine body model 3) based on the input information input in the input step S1 to form the machine body. The behavior of the hose body 2'during the operation of 3'is continuously simulated.
In the simulation process, the processing unit 11 calculates the shape of the hose unit 21 of the hose body model 2 in the initial state SS based on the hose body attachment information in the input information, and also calculates the hose body attachment information and the hose body in the input information. Based on the movable range information, the state of the hose body model 2 (the orientation of the metal fittings 221, 222, the shape of the hose 21, etc.) at each predetermined time after the initial state SS is calculated.
When the simulation model M includes the machine model 3 and the machine model 3 is set to move, the machine model 3 may be made to move according to the machine information in the input information during the simulation (its). In this case, the processing unit 11 does not simulate the behavior of the aircraft model 3), or the processing unit 11 may simulate the behavior of the aircraft model 3 based on the aircraft information.

In the determination step S3 (and by extension, the determination process), the processing unit 11 performs the determination process based on the result of the simulation step S2 (and by extension, the simulation process). In the present embodiment, the processing unit 11 makes a reverse determination in the determination process. In the inversion determination, the processing unit 11 determines whether or not there is an abnormality based on whether or not the hose 21'of the hose body 2'is inverted. Here, "reversal" of the hose 21'of the hose body 2'means a phenomenon in which the position of the center of curvature of the hose 21'changes from one side to the other side with respect to the hose 21'at least a part of the hose 21'. Point to. The same applies to the "reversal" of the hose portion 21 of the hose body model 2. For example, in the example of FIG. 14, during the return operation of the hose body model 2, the center of curvature 21c of the same part of the hose portion 21 of the hose body model 2 is from the lower side of the drawing with respect to the hose portion 21 with respect to the hose portion 21. It has moved to the upper side of the drawing, and by extension, an inversion has occurred. When the processing unit 11 determines that the hose 21'of the hose body 2'has been inverted, it determines that there is an abnormality, while when it determines that the hose 21'of the hose body 2'has not inverted, there is no abnormality. Judge.
If the hose 21'of the hose body 2'is inverted, the hose 21'may be damaged. According to the reversal determination, it is possible to avoid attaching the hose body 2'to the machine body 3', which causes damage to the hose 21'during the use of the machine 4'.

Here, in the inversion determination, the processing unit 11 per unit time in at least a part of the hose 21'of the hose body 2'at any time during the operation of the machine 3'based on the result of the simulation processing. The curvature change rate determination may be performed, in which it is determined whether or not the hose 21'of the hose body 2'is inverted based on whether or not the change rate of the curvature exceeds a predetermined curvature change rate threshold. Here, the "curvature" of the hose 21'of the hose body 2'is basically as described in the bending determination described above, but in the inversion determination, when the center of curvature is on one side of the hose 21'. It is preferable to define the curvature of (+) as "positive (+)" and the curvature when the center of curvature is on the other side of the hose 21'as "negative (-)" because the reversal judgment can be made more accurately. .. However, "curvature" may always be defined as "positive (+)" regardless of the position of the center of curvature. The same applies to the "curvature" of the hose portion 21 of the hose body model 2.
In this case, the processing unit 11 determines each time of each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3') along the extending direction of the hose part 21 of the hose body model 2. The rate of change of curvature per unit time at each position at each interval is calculated. The calculation of the rate of change of the curvature per unit time may be performed in the simulation step S2 or in the determination step S3. Then, in the determination of the rate of change in curvature in the determination step S3, the processing unit 11 changes the curvature per unit time of the hose unit 21 of the hose body model 2 at each time during the operation of the simulation model M. The rate and the predetermined curvature change rate threshold are compared, and as a result, at any time during the operation of the simulation model M, the change rate of the curvature per unit time in at least a part of the hose portion 21 of the hose body model 2 is determined. When it is determined that the predetermined curvature change rate threshold is exceeded, it is determined that the hose portion 21 of the hose body model 2 (and by extension, the hose 21'of the hose body 2') is reversed at any time during the operation of the machine body 3'. On the other hand, in other cases, it is determined that the hose portion 21 of the hose body model 2 (and thus the hose 21'of the hose body 2') did not reverse at any time during the operation of the machine body 3'.

Alternatively, in the reversal determination, the processing unit 11 bends at least a part of the hose 21'of the hose body 2'at any time during the operation of the machine 3'based on the result of the simulation processing. A bending radius change rate determination may be made to determine whether or not the hose 21'of the hose body 2'has been inverted based on whether the radius change rate exceeds a predetermined bending radius change rate threshold. Here, the "bending radius" of the hose 21'of the hose body 2'is basically as described in the above-mentioned bending determination, but in the reversal determination, the center of curvature is on one side of the hose 21'. If the bending radius at the time is defined as "positive (+)" and the bending radius when the center of curvature is on the other side of the hose 21'is defined as "negative (-)", the reversal judgment can be made more accurately. Suitable. However, the "bending radius" may always be defined as "positive (+)" regardless of the position of the center of curvature. The same applies to the "bending radius" of the hose portion 21 of the hose body model 2.
In this case, the processing unit 11 determines each time of each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3') along the extending direction of the hose part 21 of the hose body model 2. The rate of change of the bending radius per unit time at each position at each interval is calculated. The calculation of the rate of change of the bending radius per unit time may be performed in the simulation step S2 or in the determination step S3. Then, in the determination of the bending radius change rate in the determination step S3, the processing unit 11 determines the bending radius per unit time at each position of the hose unit 21 of the hose body model 2 at each time during the operation of the simulation model M. As a result, at any time during the operation of the simulation model M, the bending radius per unit time of at least a part of the hose portion 21 of the hose body model 2 is compared with the rate of change of the predetermined bending radius. When it is determined that the rate of change exceeds the predetermined bending radius rate of change threshold, the hose portion 21 of the hose body model 2 (and thus the hose 21'of the hose body 2') at any time during the operation of the machine body 3'. On the other hand, in other cases, the hose portion 21 of the hose body model 2 (and by extension, the hose 21'of the hose body 2') is reversed at any time during the operation of the machine body 3'. Judge that it was not.

Alternatively, in the reversal determination, the processing unit 11 pulls the hose body 2'at least a part of the hose 21'at any time during the operation of the machine body 3'based on the result of the simulation processing. The tensile force change rate determination may be performed, in which it is determined whether or not the hose 21'of the hose body 2'is inverted based on whether the force change rate exceeds a predetermined tensile force change rate threshold. Here, the "tensile force" of the hose 21'of the hose body 2'is defined as "positive (+)" when the center of curvature is on one side of the hose 21'in the reversal determination, and the curvature is defined. It is preferable to define the tensile force when the center is on the other side of the hose 21'as "negative (-)" because the reversal judgment can be made more accurately. However, the "tensile force" may always be defined as "positive (+)" regardless of the position of the center of curvature. The same applies to the "tensile force" of the hose portion 21 of the hose body model 2.
In this case, the processing unit 11 determines each time of each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3') along the extending direction of the hose part 21 of the hose body model 2. The rate of change in tensile force per unit time at each position at each interval is calculated. The calculation of the rate of change in the tensile force per unit time may be performed in the simulation step S2 or in the determination step S3. Then, in the determination of the tensile force change rate in the determination step S3, the processing unit 11 determines the tensile force per unit time at each position of the hose unit 21 of the hose body model 2 at each time during the operation of the simulation model M. As a result, at any time during the operation of the simulation model M, the tensile force per unit time of at least a part of the hose portion 21 of the hose body model 2 is compared with the rate of change of the predetermined tensile force change rate threshold. When it is determined that the rate of change exceeds the predetermined rate of change in tensile force threshold, the hose portion 21 of the hose body model 2 (and by extension, the hose 21'of the hose body 2') is used at any time during the operation of the machine body 3'. On the other hand, in other cases, the hose portion 21 of the hose body model 2 (and by extension, the hose 21'of the hose body 2') is reversed at any time during the operation of the machine body 3'. Judge that it was not.

Alternatively, in the inversion determination, the processing unit 11 compresses at least a part of the hose 21'of the hose body 2'at any time during the operation of the machine 3'based on the result of the simulation processing per unit time. A compressive force change rate determination may be made, in which it is determined whether or not the hose 21'of the hose body 2'is inverted based on whether or not the force change rate exceeds a predetermined compressive force change rate threshold. Here, the "compressive force" of the hose 21'of the hose body 2'is defined as "positive (+)" when the center of curvature is on one side of the hose 21'in the reversal determination, and the curvature is defined. It is preferable to define the compressive force when the center is on the other side of the hose 21'as "negative (-)" because the reversal judgment can be made more accurately. However, the "compressive force" may always be defined as "positive (+)" regardless of the position of the center of curvature. The same applies to the "compressive force" of the hose portion 21 of the hose body model 2.
In this case, the processing unit 11 determines each time of each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3') along the extending direction of the hose part 21 of the hose body model 2. The rate of change in the compressive force per unit time at each position at each interval is calculated. The calculation of the rate of change of the compressive force per unit time may be performed in the simulation step S2 or in the determination step S3. Then, in the determination of the compressive force change rate in the determination step S3, the processing unit 11 determines the compressive force per unit time at each position of the hose unit 21 of the hose body model 2 at each time during the operation of the simulation model M. As a result, at any time during the operation of the simulation model M, the compressive force per unit time in at least a part of the hose portion 21 of the hose body model 2 is compared with the rate of change of the predetermined compressive force. When it is determined that the rate of change exceeds the predetermined rate of change in compressive force threshold, the hose portion 21 of the hose body model 2 (and by extension, the hose 21'of the hose body 2') at any time during the operation of the machine body 3'. On the other hand, in other cases, the hose portion 21 of the hose body model 2 (and by extension, the hose 21'of the hose body 2') is reversed at any time during the operation of the machine body 3'. Judge that it was not.

In the reversal determination, the processing unit 11 may make any plurality of determinations among the above-mentioned curvature change rate determination, bending radius change rate determination, tensile force change rate determination, and compressive force change rate determination. In that case, the processing unit 11 determines that there is an abnormality when it is determined that the hose 21'of the hose body 2'has been inverted in each of the plurality of determinations, and in other cases, there is no abnormality. You may judge that. Alternatively, when the processing unit 11 determines that the hose 21'of the hose body 2'has been inverted in any one of the plurality of determinations in the inversion determination, it is determined that there is an abnormality, and in other cases. , It may be judged that there is no abnormality.

The post-judgment processing step S4 (and thus the post-judgment processing) is the same as that of the first embodiment.

<Sixth Embodiment of Hose Body Attachment Support Method-When Judging the Mouth>
Next, the hose body attachment support method according to the sixth embodiment of the present invention will be described in detail with reference to FIGS. 15 to 16. In the sixth embodiment, the processing unit 11 makes a mouth judgment in the judgment step S3 (and by extension, the judgment processing). The machine 4'may be, for example, a construction machine (for example, a hydraulic excavator, a wheel loader, etc.) or a factory facility (for example, an injection molding machine, a die casting machine, etc.).
In the description of the present embodiment, for convenience, the illustration of the machine 4'which is the target of the simulation in the simulation step S2 (and thus the simulation process) is omitted.

The input step S1 (and thus the input process) and the simulation step S2 (and thus the simulation process) are performed in the same manner as in the first embodiment.
FIG. 15 shows an image of how the simulation model M operates in the simulation in the simulation step S2 (and thus the simulation process) in this example. In this example, the simulation model M has only the hose body model 2 that imitates the hose body 2', and does not have the machine body model 3 that imitates a part of the machine body 3'. However, the simulation model M may have an airframe model 3.

The input information input in the input step S1 includes at least the hose body attachment information and the hose body movable range information. When the simulation model M includes the machine model 3, the input information input in the input step S1 further includes the machine information.
In the example of FIG. 15, the hose body movable range information is fixed so that the second end portion 2b of the hose body model 2 does not move, and the first end portion 2a of the hose body model 2 is the rotation axis from the initial state SS. Rotate one side in the circumferential direction (clockwise in FIG. 15) around 3c by a predetermined angle to reach the maximum degree state SM, and then determine the other side in the circumferential direction (counterclockwise in FIG. 15) around the rotation axis 3c. It is specified that the rotation is performed by an angle and the final state SF is the same as the initial state SS.

In the simulation step S2 (and by extension, the simulation process), the processing unit 11 operates the machine body 3'using the simulation model M (in this example, the hose body model 2) based on the input information input in the input step S1. The behavior of the hose body 2'inside is continuously simulated.
In the simulation process, the processing unit 11 calculates the shape of the hose unit 21 of the hose body model 2 in the initial state SS based on the hose body attachment information in the input information, and also calculates the hose body attachment information and the hose body in the input information. Based on the movable range information, the state of the hose body model 2 (the orientation of the metal fittings 221, 222, the shape of the hose 21, etc.) at each predetermined time after the initial state SS is calculated.
When the simulation model M includes the machine model 3 and the machine model 3 is set to move, the machine model 3 may be made to move according to the machine information in the input information during the simulation (its). In this case, the processing unit 11 does not simulate the behavior of the aircraft model 3), or the processing unit 11 may simulate the behavior of the aircraft model 3 based on the aircraft information.

In the determination step S3 (and by extension, the determination process), the processing unit 11 performs the determination process based on the result of the simulation step S2 (and by extension, the simulation process). In the present embodiment, the processing unit 11 makes a mouth judgment in the judgment processing. In the mouth determination, the processing unit 11 determines whether or not there is an abnormality based on whether or not the mouth portion 21k'(FIG. 2) of the hose 21'of the hose body 2'is excessively deformed. Here, the "mouth portion 21k'" (FIG. 2) of the hose 21'of the hose body 2'is about 100 mm from the end portion 22d'on the hose 21'side of the metal fittings 221' and 222'of the hose 21'. Refers to the part of. The same applies to the mouth portion 21k (FIG. 15) of the hose portion 21 of the hose body model 2. The processing unit 11 may make a mouth judgment on only one of the pair of mouth portions 21k'of the hose 21', or may make a mouth judgment on both of the pair of mouth portions 21k'of the hose 21'. You may go. In the example of FIG. 15, the processing unit 11 is a pair of mouth portions 21k'of the pair of mouth portions 21k'of the hose portion 21', which is adjacent to the second metal fitting 222'(and by extension, a pair of hoses 21 of the hose body model 2). Of the mouth portion 21k, the mouth portion 21k) adjacent to the second metal fitting portion 222) is determined. When the processing unit 11 determines that the mouth portion 21k'of the hose 21'of the hose body 2'is excessively deformed, it determines that there is an abnormality, while the processing unit 11 determines that there is an abnormality, while the mouth portion 21k'of the hose 21'of the hose body 2'. If it is judged that the hose has not been deformed excessively, it is judged that there is no abnormality.
If the mouth portion 21k'of the hose 21' of the hose body 2'is excessively deformed, the mouth portion 21k' of the hose 21'may be damaged. According to the judgment of the mouth, it is possible to avoid attaching the hose body 2'to the machine body 3', which causes damage to the mouth portion 21k' of the hose 21'during the use of the machine 4'.

Here, in the mouth determination, the processing unit 11 determines that the mouth portion 21k'is adjacent to the mouth portion 21k' during the operation of the machine 3'based on the result of the simulation processing, and the metal fittings 221' and 222'(this example). Then, the mouth portion of the hose 21'of the hose body 2'is based on whether or not it has moved from one side to the other side with respect to the extension line 22c'(not shown) of the central axis of the second metal fitting 222'). A double swing judgment may be made to determine whether or not 21k'has been excessively deformed.
In this case, in the double swing determination in the determination step S3, the processing unit 11 has the mouth portion 21k of the hose 21 of the hose body model 2 adjacent to the mouth portion 21k during the operation of the simulation model M. It is determined whether or not the central axis of the (second metal fitting portion 222 in this example) has moved from one side to the other side with respect to the extension line 22c, and as a result, the hose body model 2 is operated during the operation of the simulation model M. The mouth portion 21k has moved from one side to the other side with respect to the extension line 22c of the central axis of the metal fittings portions 221 and 222 (second metal fittings portion 222 in this example) adjacent to the mouth portion 21k (and by extension, the hose body). The mouth portion 21k'of 2'is from either one side to the other side of the extension line 22c' of the central axis of the metal fittings 221' and 222'(in this example, the second metal fitting 222') adjacent to the mouth portion 21k'. When it is determined that the hose body model 2 has moved), it is determined that the mouth portion 21k of the hose portion 21 of the hose body model 2 (and thus the mouth portion 21k'of the hose 21'of the hose body 2') is excessively deformed. In this case, it is determined that the mouth portion 21k of the hose portion 21 of the hose body model 2 (and thus the mouth portion 21k'of the hose 21'of the hose body 2') was not excessively deformed.

Alternatively, in the mouth determination, whether the bending radius of the mouth portion 21k'is lower than the predetermined mouth bending radius threshold at any time during the operation of the machine 3'based on the result of the simulation processing. Based on whether or not, the mouth portion bending radius may be determined to determine whether or not the mouth portion 21k'of the hose 21'of the hose body 2'is excessively deformed. The predetermined mouth portion bending radius threshold value is preferably set to a minimum bending radius predetermined by, for example, the manufacturer of the hose body 2', but may be set to a different value.
The bending radius defines the curvature when the center of curvature is on one side with respect to the hose 21'as "positive (+)", and the curvature when the center of curvature is on the other side with respect to the hose 21'is "negative (" It may be defined as "-)", or it may be defined as always "positive (+)" regardless of the position of the center of curvature. In the former case, in the comparison with the predetermined mouth portion bending radius threshold value, the absolute value of the bending radius and the predetermined mouth portion bending radius threshold value shall be compared.
In this case, the processing unit 11 extends the mouth portion 21k of the hose portion 21 of the hose body model 2 for each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3'). The bending radius at each position at predetermined intervals along the above is calculated. The calculation of the bending radius may be performed in the simulation step S2 or in the determination step S3. Then, in determining the bending radius of the mouth portion in the determination step S3, the processing unit 11 determines the bending radius of the mouth portion 21k of the hose portion 21 of the hose body model 2 at each time during the operation of the simulation model M at each of the above positions. And the predetermined mouth portion bending radius threshold are compared, and as a result, at any time during the operation of the simulation model M, the bending radius of at least a part of the mouth portion 21k of the hose portion 21 of the hose body model 2 is the predetermined mouth portion. When it is determined that the bending radius threshold has been exceeded, the mouth portion 21k of the hose portion 21 of the hose body model 2 (and by extension, the mouth portion of the hose 21'of the hose body 2') is used at any time during the operation of the machine body 3'. It is determined that the 21k') has been excessively deformed, while in other cases, at any time during the operation of the machine 3', the mouth portion 21k (and thus the hose body 2) of the hose portion 21 of the hose body model 2 is determined. It is judged that the mouth portion 21k') of the'hose 21'was not excessively deformed.

Alternatively, in the mouth determination, the processing unit 11 determines whether or not the curvature of the mouth portion 21k'exceeds the predetermined mouth portion curvature threshold at any time during the operation of the machine 3'based on the result of the simulation processing. Based on the above, the curvature of the mouth may be determined to determine whether or not the mouth portion 21k'of the hose 21'of the hose body 2'is excessively deformed. The predetermined mouth portion curvature threshold value is preferably set to a curvature converted from the minimum bending radius predetermined by, for example, the manufacturer of the hose body 2', but may be set to a different value.
For the above curvature, the curvature when the center of curvature is on one side with respect to the hose 21'is defined as "positive (+)", and the curvature when the center of curvature is on the other side with respect to the hose 21'is "negative (-)". ) ”, Or it may be defined to always be“ positive (+) ”regardless of the position of the center of curvature. In the former case, in the comparison with the predetermined mouth portion curvature threshold value, the absolute value of the curvature and the predetermined mouth portion curvature threshold value shall be compared.
In this case, the processing unit 11 extends the mouth portion 21k of the hose portion 21 of the hose body model 2 for each predetermined time during the operation of the simulation model M (and by extension, the operation of the machine body 3'). The curvature at each position at predetermined intervals along the above is calculated. The calculation of the curvature may be performed in the simulation step S2 or in the determination step S3. Then, in the determination of the mouth portion curvature in the determination step S3, the processing unit 11 determines the curvature at each of the above positions of the mouth portion 21k of the hose portion 21 of the hose body model 2 at each time during the operation of the simulation model M. As a result of comparison with the mouth portion curvature threshold, the curvature of at least a part of the mouth portion 21k of the hose portion 21 of the hose body model 2 at any time during the operation of the simulation model M determines the predetermined mouth portion curvature threshold. When it is determined that the amount has been exceeded, the mouth portion 21k of the hose portion 21 of the hose body model 2 (and thus the mouth portion 21k'of the hose 21'of the hose body 2') is excessive at any time during the operation of the machine body 3'. On the other hand, in other cases, the mouth portion 21k of the hose portion 21 of the hose body model 2 (and by extension, the hose 21'of the hose body 2') is used at any time during the operation of the machine body 3'. It is judged that the mouth portion 21k') was not excessively deformed.

In the mouth determination, the processing unit 11 may make any plurality of determinations among the above-mentioned double swing determination, the mouth portion bending radius determination, and the mouth portion curvature determination. In that case, the processing unit 11 determines that there is an abnormality when it is determined in the mouth determination that the mouth portion 21k'of the hose 21'of the hose body 2'is excessively deformed in each of the plurality of judgments. In other cases, it may be determined that there is no abnormality. Alternatively, when the processing unit 11 determines in any one of the plurality of determinations that the mouth portion 21k'of the hose 21'of the hose body 2'is excessively deformed, it is determined that there is an abnormality. However, in other cases, it may be determined that there is no abnormality.

The post-judgment processing step S4 (and thus the post-judgment processing) is the same as that of the first embodiment.

Note that FIG. 16 shows an example of FIG. 15 in the input step S1 (and thus the input process) through the hose body attachment information change step (and by extension, the hose body attachment information change process) in the post-judgment process step S4 (and by extension, the post-judgment process). The image of the simulation model M in which the hose body mounting information different from the hose body mounting information input to the simulation model M is input is shown. The simulation model M of the example of FIG. 16 has an initial orientation of the first end portion 2a and the second end portion 2b of the hose body model 2 set by the hose body initial orientation information with respect to the simulation model M of the example of FIG. Only the length of the hose portion 21 set by the hose length information of the hose dimension information and the shape of the first metal fitting portion 221 set by the metal fitting shape information of the metal fitting information are different. In the example of FIG. 16, during the operation of the simulation model M, the mouth portion 21k of the hose 21 of the hose body model 2 is the central axis of the metal fittings 221 and 222 (in this example, the second metal fitting 222) adjacent to the mouth portion 21k. Since it stays on one side of the extension line 22c (left side of FIG. 16) and does not move to the other side of the extension line 22c (right side of FIG. 16), it corresponds to the simulation model M of the example of FIG. It can be seen that the hose body 2'is properly attached to the machine body 3'.

In each of the above-described embodiments, the processing unit 11 may perform a correction step (and thus a correction process) before the simulation step S2 (and thus the simulation process).

Entered. Here, the working pressure of the hose body 2'specified by the working pressure information may be, for example, the maximum working pressure predetermined by the manufacturer of the hose body 2', or is actually normally used.

Then, after the correction step (and by extension, the correction process), the processing unit 11 performs the simulation step S2 (and by extension, the simulation process) using the input information including the hose rigidity information and the hose dimension information corrected by the correction process.
Generally, the rigidity (particularly, bending rigidity) of the hose 21'is higher as the working pressure is higher. The length of the hose 21'varies depending on the working pressure, depending on the structure and material of the hose. Further, the outer diameter of the hose 21'is larger as the working pressure is higher. According to the correction process, the simulation can be performed after considering the change in the rigidity and the dimensions of the hose 21'according to the working pressure, so that a more accurate simulation can be performed, and by extension, the machine 3'. Proper mounting of the hose body 2'can be supported more effectively.
In the correction step (and by extension, the correction process), it is preferable that the processing unit 11 corrects the hose rigidity information so that the higher the working pressure, the higher the rigidity specified by the hose rigidity information. Further, in the correction step (and by extension, the correction process), the processing unit 11 increases the hose length information so that the length of the hose 21'specified by the hose length information in the hose dimension information becomes shorter as the working pressure increases. It is preferable to correct. Further, in the correction step (and by extension, the correction process), the processing unit 11 increases the hose outer diameter information so that the higher the working pressure, the larger the outer diameter of the hose 21'specified by the hose outer diameter information in the hose dimension information. It is preferable to correct.
