Description
Technical Field
The present invention relates to a fishing rod evaluation method for objectively evaluating the performance of a fishing rod based on dynamic physical characteristics.
Background
Various characteristics are required for fishing rods. Among the characteristics that are considered important in designing fishing rods, there are physically measurable characteristics, such as the bending stiffness and torsional stiffness of the rod body.
The bending stiffness and the torsional stiffness are physical properties possessed by a fishing rod, and are quantitative properties, but do not reflect the actual motion of the fishing rod, that is, static physical properties and not dynamic physical properties, and therefore, there is a problem that the performance of the fishing rod cannot be objectively evaluated by such properties.
Conventionally, as a method for objectively evaluating the performance of a fishing rod, for example, japanese patent application laid-open No. 2013-153740 (patent document 1) discloses a design system for designing a long member in a tubular or plate shape made of resin by using a sensitivity evaluation based on digitalized physical elements.
However, even in the method according to patent document 1, since the so-called static physical characteristics do not always accurately reflect the actual use state, operation, and other dynamic physical characteristics of the fishing rod, it is difficult to say that the performance of the fishing rod can be objectively evaluated.

Detailed Description
Hereinafter, various embodiments of the present invention will be described with reference to the drawings as appropriate. In the drawings, the same reference numerals are given to the common components. For convenience of explanation, it should be noted that the drawings are not necessarily described in the correct scale.
Fig. 1 is a schematic view showing the overall configuration of a strain energy measurement system 1 used in a fishing rod evaluation method (hereinafter, simply referred to as an evaluation method) according to the present invention. As shown in fig. 1, the measurement system 1 is composed of a fishing rod 10 in which markers 8 are marked at 11 positions that are predetermined positions of the rod, a weight 20 attached to one end of the fishing rod 10, and a camera 30 that captures the markers 8. When an operator holds the fishing rod 10 and performs a fishing operation, the camera 30 captures the marker 8, thereby measuring changes in the entire rod and the marked predetermined positions.
The measurement system 1 may be further provided with a holding device for holding the fishing rod 20. Further, the measurement system 1 may be combined with a different device other than the fishing rod 10, the weight 20, and the camera 30.
In this way, the illustrated measurement system 1 detects the speed and acceleration of the fishing rod 10 and the coordinates of each predetermined position of the fishing rod when the fishing rod is used. Then, the strain energy of the fishing rod 10 is calculated from the curvature and rigidity based on the coordinates of each predetermined position of the fishing rod, and evaluated. More details are as follows.
An evaluation method according to an embodiment of the present invention will be described with reference to fig. 2. In the evaluation method according to one embodiment of the present invention, first, in (S1), the curvature and rigidity based on the coordinates of each predetermined position of the fishing rod 10 are detected. Next, in (S2), the speed and acceleration of the fishing rod 10 when the fishing rod 10 is used are detected by the measurement system 1. Here, the process may be performed before (S2) or simultaneously with (S1). That is, in (S3), although the detection information in (S1) and (S2) is required, this does not mean that the order of detection itself has a meaning, and the order may be changed as appropriate.
Next, in (S3), strain energy and changes thereof at predetermined positions from the rod tip to the rod rear portion of the fishing rod 10 when the fishing rod 10 is used are calculated based on the information of the fishing rod 10 detected in (S1).
Then, the fishing rod is evaluated based on the change in strain energy at each predetermined position calculated in (S3). Here, in the evaluation of the fishing rod, the speed and acceleration of the fishing rod 10 detected in (S2) may be used in addition to the change in the strain energy at each predetermined position.
With the evaluation method according to one embodiment of the present invention, since dynamic data of the strain energy of the fishing rod is used, it is possible to perform more objective and accurate performance evaluation of the fishing rod according to the actual use state, operation, and the like of the fishing rod.
In the evaluation method according to one embodiment of the present invention, the calculation of the strain energy at a predetermined position of the fishing rod is extraction of time-series data of the strain energy at the predetermined position. In this way, time-series data of strain energy at a predetermined position of the fishing rod is used, and therefore, it is possible to perform more objective and accurate performance evaluation of the fishing rod according to the actual use state, operation, and the like of the fishing rod.
An evaluation method according to an embodiment of the present invention evaluates the performance of a fishing rod based on a change in strain energy at a predetermined position of the fishing rod and a usage form of the fishing rod. This is because the performance evaluation of the fishing rod is considered to be different depending on the use form of the fishing rod. Thus, the performance of the fishing rod can be more accurately evaluated according to the use form of the fishing rod.
In the evaluation method according to one embodiment of the present invention, the usage form of the fishing rod is a casting operation of the fishing rod.
In the evaluation method according to one embodiment of the present invention, the usage form of the fishing rod is a fishing rod pulling-in operation.
In the evaluation method according to one embodiment of the present invention, the use form of the fishing rod is a fishing rod lifting operation.
In an evaluation method according to an embodiment of the present invention, a load applied to a fisherman holding the fishing rod in accordance with the change in strain energy is calculated, and the fishing rod is evaluated based on the load. This makes it possible to evaluate the performance of the fishing rod in consideration of the load applied to the fisherman.
In the evaluation method according to one embodiment of the present invention, the change in the strain energy is accumulation and release of the strain energy at a predetermined position of the fishing rod. In addition, an evaluation method according to an embodiment of the present invention is an evaluation method for a fishing rod based on a change in strain energy at a part of a position as a predetermined position of the fishing rod.
An example of the evaluation method according to an embodiment of the present invention will be specifically described with reference to fig. 3 to 8. First, fig. 3a and b show the usage pattern of 2 kinds of fishing rods (rod C, D) as the temporal change of the strain energy at a predetermined position of the fishing rod during the casting operation, and fig. 3c shows the usage pattern of 2 kinds of fishing rods as the temporal change of the speed of the lure during the casting operation. In fig. 3a and b, the horizontal axis represents time, and the vertical axis represents strain energy. In fig. 3c, the horizontal axis represents time, and the vertical axis represents the lure speed.
Fig. 3d shows the use pattern of 2 kinds of fishing rods as the time change of the total strain energy of the fishing rod during the casting operation. In fig. 3d, the horizontal axis represents time and the vertical axis represents total strain energy.
As shown in fig. 3a and b, the strain energy is concentrated on the whole of the rod C, D from the start of the casting action, but the situation in which more strain energy is concentrated toward the rod root end is shown as a time series. Thus, when the fishing rod is used in a casting mode, it can be confirmed at which time and in which section the most concentrated strain energy is obtained.
In particular, it is known that the most strain energy is accumulated in the rod D at an earlier time, and more strain energy is accumulated in the rod base end portion of the fishing rod of the rod D than in the rod base end portion of the fishing rod of the rod C. Here, the section means each section of the rod when the section from the rod tip end to the rod root end of the rod is properly divided into 10 sections, from the rod tip end (section 1) to the rod root end (section 10).
As shown in fig. 3c, it is known that although the rod C, D is all operating the fishing rod at the same casting speed, the rod D is faster after time 4 with respect to the lure speed, and the speed continues to increase until time 20. As shown in fig. 3D, it is also known that the total strain energy of the rod D is maximized earlier (the rod D is maximized in the vicinity of time 8, and the rod C is maximized in the vicinity of time 11), and the amount of the total strain energy accumulated is also increased, and thereafter, more energy is released.
As such, if reference is made to the data of time series change of strain energy of fig. 3a, b, d, it is known that strain energy is accumulated, and in the process of being released thereafter, the strain energy of the rod causes an increase in the speed of the lure.
In this way, when the usage form of the fishing rod is the casting operation, it is possible to accurately predict what kind of rod can further increase the speed of the lure from the time change of each section of the strain energy of each rod and the time change of the total strain energy of each rod.
With the evaluation method according to one embodiment of the present invention, since dynamic data such as strain energy of the fishing rod is used, it is possible to perform more objective and accurate performance evaluation of the fishing rod according to the actual use state, operation, and the like of the fishing rod.
Next, fig. 4 shows a temporal change in strain energy of the entire fishing rod when the fishing rod is used in a form of a pulling-up operation of the fishing rod. In fig. 4, the horizontal axis represents time and the vertical axis represents strain energy for each of the rods a and B. The time from the start of the drawing to the end thereof is 20 parts, and the time is 0 to 20.
As shown in the figure, it is known that the strain energy of the rod B is greatly accumulated and released at a burst during the period from the start of the pulling-up operation to time 5. From this, it is known that the rod B can approach the fish earlier than the rod a.
Then, in the period of time 5-8, the rod B is in a state of gathering strain energy, and the rod A is in balance between gathering and releasing of strain energy. From this, it is known that the fish hardly moves in the case of the rod B, and the approach of the fish is substantially constant in the case of the rod a.
During the time period of 8 to 14, it is known that the accumulation of the strain energy of the rod B is not stable. On the other hand, it is known that the build-up of strain energy in the rod a is relatively stable. This revealed that the rod a can approach the fish at a constant speed, and the difference from the rod B is increased. This is considered to be because the rod B tends to shake the rod easily, and the continuity of rigidity between the nodes is poor.
Next, during the period after time 14, both the rod a and the rod B release the same strain energy as the whole rod.
FIG. 5 shows the temporal change of strain energy in the rod sections 7 to 11 (section 02) of the rods A and B. Here, the section means each section when each rod is divided into 4 sections, and is divided into the 01 st section to the 04 th section from the rod tip end to the rod root end of each rod. Each section is also divided into sections, section 01 is divided into sections 1-6, section 02 is divided into sections 7-11, section 03 is divided into sections 12-15, and section 04 is divided into sections 16-18. The mark positions in each section are 7 positions on section 01, 5 positions on section 02, 4 positions on section 03, and 3 positions on section 04. The number of positions of the marker can be appropriately changed according to the length of the rod (length of the section) and the state of the rod (whether the rod is easily bent or not easily bent, etc.). The sections may be separated at regular intervals, or may be provided at narrower intervals as they extend toward the rod tip. In the case of fig. 5, the section can be provided at a narrower interval at the rod tip where the rod is easily deformed, but other methods may be employed. The horizontal axis represents time, and the vertical axis represents strain energy. As shown in the figure, in this rod section, it is found that the strain energy of both the rod a and the rod B tends to increase from the beginning to the end. Further, it is known that the concentration of strain energy at the front and rear positions of the rod a passing section 10 is larger than that at the same position of the rod B. As described above, the rod a is stable when the rod is erected and the fish is pulled close, and has a great effect of suppressing the movement of the fish. Further, it is known that the angler can lift the fish at his will without making the fish stand ahead and then resistant to the uplift force.
FIG. 6 shows the temporal change of strain energy in the rod sections 16 to 18 (section 04) of the rods A and B. Here, the section means each section when each rod is divided into 4 sections, and is divided into the 01 st section to the 04 th section from the rod tip end to the rod root end of each rod. Each section is also divided into sections, section 01 is divided into sections 1-6, section 02 is divided into sections 7-11, section 03 is divided into sections 12-15, and section 04 is divided into sections 16-18. The sections may be spaced at even intervals or may be spaced at narrower intervals as one moves toward the rod tip. In the case of fig. 6, it is preferable to provide the section at a narrower interval at the tip of the rod where the rod is easily deformed, but other methods may be employed. The horizontal axis represents time, and the vertical axis represents strain energy. Since the rod is initially horizontal, it plays an important role in the movement of the fish. As shown in the figure, the strain energy of the rod B is increased immediately after the start, but the strain energy is gradually released as the rod rises. The approach of the fish is temporarily halted due to the continuous poor stiffness between the segments on the rod B. On the other hand, as shown in the figure, although the accumulation of the strain energy does not become large immediately after the start, the balance of the accumulation and release of the strain energy is good, and therefore the fish can approach stably.
As will be understood from fig. 5 and 6, the energy of the root end segment is concentrated more on the rod B until the end, but the energy is gradually reduced on the rod a, so that the rod tip moves so as to be more responsible for the approaching action of the fish as the fish approaches the front side.
With the evaluation method according to one embodiment of the present invention, since dynamic data of the strain energy of the fishing rod is used, it is possible to perform more objective and accurate performance evaluation of the fishing rod according to the actual use state, operation, and the like of the fishing rod.
Next, referring to fig. 7 and 8, the temporal change of strain energy and the change of support force of a person when the fishing rod is used in a fishing rod lifting (especially, crucian carp) operation are shown, respectively. In fig. 7, the horizontal axis represents time and the vertical axis represents strain energy for each of the rods a and B. The time from the start of fish lifting to the end thereof is shown in 15 portions. In fig. 8, the horizontal axis represents time and the vertical axis represents human supporting force for each of the rods a and B. Similarly, the time from the start of fish lifting to the end thereof is 15 parts.
As can be seen from these figures, the accumulation and release of strain energy on the rod B do not proceed smoothly, and the variation in the supporting force of the person is large. On the other hand, it is known that the accumulation and release of strain energy in the rod a are efficiently performed over the entire span of the operation, and the supporting force of the person is stably transmitted over approximately 90% of the rod B. As described above, it is found that the rod a can perform the fish lifting operation earlier than the rod B, and the load on the person is small.
With the evaluation method according to one embodiment of the present invention, since dynamic data of the strain energy of the fishing rod is used, it is possible to perform more objective and accurate performance evaluation of the fishing rod according to the actual use state, operation, and the like of the fishing rod.
Here, the performance evaluation of the fishing rod according to the embodiment of the present invention can be used for evaluating the fitting operation, that is, convergence of the shake of the rod tip and the reaction speed of the rod tip. The performance evaluation of the fishing rod according to the embodiment of the present invention can be used for evaluating the handling performance of a fishing group, a lure, or the like. The performance evaluation of the fishing rod according to the embodiment of the present invention can be used for evaluating sensitivity, that is, a fish-hooking signal and the movement of the lure.
The dimensions, materials, and arrangements of the constituent elements described in the present specification are not limited to those explicitly described in the embodiments, but may be modified to have any dimensions, materials, and arrangements included in the scope of the present invention. In addition, components not explicitly described in the present specification may be added to the embodiments described above, and a part of the components described in each embodiment may be omitted.
