Abstract

A test buck, a test buck system and related method are disclosed. The test buck system may comprise a controller and a test buck. The test buck may include a portable bed, a seat module mounted to the bed, and a first OIM disposed on the bed. At least a portion of the first OIM may be selectively moveable in at least four degrees of freedom, up to six degrees of freedom. The controller may be electrically connected to a first Operator Interface Module (OIM). The controller may be configured to selectively move at least a portion of the first OIM in at least four to six degrees of freedom.

Claims

1. A test buck system comprising:

a test buck, the test buck including;

a portable bed;

a seat module mounted to the bed; and

a first OIM disposed on the bed, at least a portion of the first OIM selectively moveable in four degrees of freedom; and

a controller electrically connected to the first OIM of the test buck, the controller configured to selectively move at least a portion of the first OIM in four degrees of freedom.

2. The test buck system of claim 1, wherein the bed is configured to be removeably mounted to a platform of a dynamic ride simulator.

3. The test buck system of claim 2, further including a dynamic ride simulator having a platform upon which the test buck is mounted.

4. The test buck system of claim 3, wherein the first OIM is an upper control module, the upper control module including a joystick.

5. The test buck system of claim 1, further comprising a second OIM mounted to the bed, the second OIM different from the first OIM.

6. The test buck system of claim 1, wherein the first OIM is a foot control module, the foot control module including a floor mounted pedal.

7. The test buck system of claim 1, further comprising a tower secured to the bed, wherein the first OIM is a foot control module including a suspended pedal mounted to the tower.

8. The test buck system of claim 7, in which the foot control module further includes a foot peg.

9. The test buck system of claim 1, wherein the first OIM is a steering module.

10. The test buck system of claim 1, wherein the first OIM is a display module.

11. The test buck system of claim 1, wherein at least a portion of the first OIM is selectively moveable in six degrees of freedom.

12. A test buck system comprising:

a bed configured to be removeably mounted to a test floor of a dynamic ride simulator;

a seat module mounted to the bed;

an OIM mounted to the bed, the OIM having a first portion;

a controller electrically connected to the OIM, the controller configured to selectively move at least the first portion of the OIM in the range of four to six degrees of freedom.

13. The test buck system of claim 12, wherein the controller is configured to receive a move command to move the first portion of the OIM and to transmit a movement signal to the OIM based on the move command.

14. The test buck system of claim 13, further comprising a remote operator interface, wherein the move command is received by the controller from the remote operator interface.

15. The test buck system of claim 14, wherein the move command is based on input into the remote operator interface, the input designating incremental movement of the first portion of the OIM.

16. The test buck system of claim 14, wherein the seat module has an SIP and the move command is based on input into the remote operator interface, the input designating a position relative to the SIP.

17. The test buck system of claim 13, further comprising a user interface disposed on the bed, wherein the move command is received by the controller from the user interface.

18. A method of determining a desired operational position of at least one OIM, the method comprising:

simulating a machine operation while one of a plurality of operators is disposed in a seat module mounted to a bed and is operating a first OIM mounted to the bed and disposed in a home position;

moving the first OIM to a final position in response to input from the operator;

generating a set of final test positions for the OIM by performing the simulating and moving steps for each of the plurality of operators; and

defining a desired operational range of adjustability and a desired operational position for the OIM based on the set of final test positions, wherein at least one final test position in the set of final test positions is different from the home position by four degrees of freedom.

19. The method claim 18, wherein the first OIM includes a joystick.

20. A method of claim 18, further comprising:

providing a second OIM mounted to the bed and disposed in a second home position; and

moving a second OIM to a second final position in response to input from the operator, wherein the second final position is different from the second home position by four degrees of freedom.
