BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation sensation generator for a simulator that simulates operation sensation.

[0002]

2. Description of the Related Art Conventionally, an operation sensation generating device for a simulator sometimes uses a friction plate or the like and sometimes uses hydraulic pressure.

FIG. 3 is a schematic diagram of an apparatus configuration when a friction plate is used. 31 is a lever for operation, 32 is a friction plate, and 33 is a brake. The operation of the lever 31 causes the friction plate 32 and the brake 33 to come into contact with each other, and the friction generates an operating force for the lever 31.

[0004] FIG. 4 is a schematic diagram of a device configuration in the case of using hydraulic pressure. 41 is a lever for operation, 42 is a hydraulic cylinder, 43 is a force sensor, 44 is a calculation processing device, and 45 is a hydraulic valve. When a force is applied to the operation lever 41, the force sensor 43 detects the force and sends an electric signal to the calculation processing device 44. Calculation processing is performed by the calculation processing device 44, and the hydraulic pressure according to the force on the lever 41 is
2 to supply hydraulic pressure to the hydraulic valve 45
Send an electrical signal to Thus, an operation reaction force is given to the operation lever 41, and an operation feeling is generated.

[0005]

When the friction plate or the like shown in FIG. 3 is used, adjustment of the operating force requires replacement of parts and cannot be performed immediately. There was also a problem that the simulation level was low.

When the hydraulic pressure shown in FIG. 4 is used, there is a problem that the apparatus becomes expensive and the mechanical structure for generating the operation reaction force is complicated.

The present invention has been made in order to solve the above-mentioned problems, and an apparatus which can adjust the operating force in real time, is less expensive than the hydraulic type, and has a higher simulation level than the friction plate type. The purpose is to gain.

[0008]

Means for Solving the Problems As means for solving the above-mentioned problems, an operation sensation generating device for a simulator according to the present invention includes an operation member, a position sensor for detecting a position of the operation member, and an operation member for the operation member. It is characterized by comprising an electromagnetic powder brake for giving a reaction force, and a calculation processing unit for calculating the operation reaction force of the operation member according to the position of the operation member from the position sensor.

[0009]

When the operation member is operated, the position sensor detects the position of the operation member, and calculates the breakout force and the friction force in the calculation processing device. The calculation result is converted into an electric signal and sent to an electromagnetic powder brake to generate an operation reaction force.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of an operation sensation generator for a simulator according to the present invention. FIG. 1 is a configuration diagram showing one embodiment. 11 is a lever as an operating member for operation, 12 is a position sensor that detects the position of the lever 11, 13 is a calculation processing unit that calculates the operation feeling according to the position and change in position of the lever 11, and converts it into an electric signal. Reference numeral 14 denotes an electromagnetic powder brake for generating an operation reaction force according to an electric signal, and reference numeral 15 denotes a gear.

When the operating lever 11 is operated, it rotates about a fulcrum 111 and this movement is transmitted through a member 112 to the gear 1.
5 is transmitted. The center of the gear 15 and the position sensor 12 are fixed, and the movement of the gear 15 is detected and sent to the calculation processing unit 13.

Based on the detected position signal, the calculation processing unit 13 calculates the operation reaction force corresponding to the position and the position change according to the flowchart of FIG. In step P1, a lever operation speed is calculated based on a change in the position of the lever 11. At this time, since the operating force varies depending on the position of the lever 11, it is determined in step P2 whether the lever 11 has exceeded a predetermined position. Then, in step P3, the frictional force F1 = K2 or F1 = K3 according to the position is calculated. Further, it is determined in Step P4 whether the change in the lever operation speed is within a predetermined value. Since the force required when the lever 11 starts to move from the stop is greater than the operating force that continues to move when the lever 11 is moving, if the determination in Step P4 is NO, the breakout force F2 = K5 in Step P5,
When the determination is YES, F2 = 0 is set. Hereinafter, in step P6, the current lever position PLEVER and lever speed VLEV
ER is updated as the previous PLEVER n-1 and VLEVER n-1, respectively. In step P7, the operation force is set as F = F1 + F2,
Give to the electromagnetic powder brake 14. The electromagnetic powder brake 14 changes the distribution of iron sand between the two shafts to be coupled by controlling the current flowing through the coil, thereby
Changes the friction between the book shafts. Therefore, the current flowing through the electromagnetic powder brake 14 can be immediately changed according to the operating force F given from the calculation processing unit 13, and the operating force can be adjusted in real time.

In the above example, only the simulation of the operational feeling has been described. However, when reproducing the other operating conditions, for example, the movement of the lever 11, it is necessary to drive the gear 15 by an external signal. K2, K explained in
3, If K5 is set to the minimum value and the operation reaction force is set to the minimum value,
It is possible to reduce the size and weight of the driving motor as compared with the case of using the friction plate of FIG. 3 described as a conventional technique.

[0014]

As described above, according to the present invention, since the operation sensation generating device for the simulator is configured as described above, the device can be inexpensive, and the operation force can be adjusted immediately.
A high simulation including the breakout force and the frictional force can be performed.
