Abstract

A system for testing an impact of a vehicle includes a rail, a cable moveable along the rail, a shuttle fixed to the cable and slideably coupled to the rail, and a cart. The cart includes a connector horizontally spaced from the rail and a centerline parallel to and horizontally spaced from the rail. An arm is fixed to the shuttle and extends from the shuttle to the connector. The arm is releasably connectable to the connector.

First claim

What is claimed is:

1. A system, comprising:
a rail;
a cable moveable along the rail;
a shuttle fixed to the cable and slideably coupled to the rail;
a cart having a connector horizontally spaced from the rail and a centerline parallel to and horizontally spaced from the rail; and
an arm fixed to the shuttle and extending from the shuttle to the connector, the arm being releasably connectable to the connector;
wherein the rail is elongated along a longitudinal axis and includes a first side and a second side opposing each other about the longitudinal axis, the cable being moveable along the first side in a first direction and along the second side in a second direction opposite the first direction.

2. The system of claim 1 , wherein the cable is a continuous loop.

3. The system of claim 1 , wherein one of the connector and the arm includes a pin, and the other of the connector and the arm includes a socket, the pin being releasably connectable to the socket.

4. The system of claim 3 , wherein the socket is pivotally connected to the other of the connector and the arm.

5. The system of claim 1 , wherein the connector is on the centerline.

6. The system of claim 1 , wherein the arm includes a wheel and an end, the end being distal to the shuttle and the wheel being attached to the end.

7. The system of claim 1 , wherein the arm is configured to pull the cart.

8. The system of claim 1 , wherein the arm is removeably mounted to the shuttle.

9. The system of claim 1 , further comprising a shock absorber removeably mounted to the rail.

10. The system of claim 9 , wherein the shock absorber is positioned relative to the rail to be impacted by the shuttle as the shuttle slides along the rail.

11. The system of claim 9 , wherein the shock absorber includes a bracket adjacent the rail, and a fastener removeably mounting the bracket to the rail.

12. The system of claim 9 , wherein the shock absorber includes a dashpot elongated along the rail.

13. The system of claim 9 , wherein the shock absorber is a honeycomb structure.

14. The system of claim 1 , further comprising a second shuttle fixed to the cable and slideably coupled to the rail, the shuttle and the second shuttle slideable along the rail in a direction toward each other.

15. The system of claim 14 , wherein the second shuttle is connected to a vehicle.

16. The system of claim 15 , further comprising a ramp mounted on the rail, wherein the second shuttle is configured to slideably engage the ramp to disconnect from the vehicle on the ramp.

17. A method, comprising:
connecting a cart to a first section of a cable with a centerline of the cart offset from a centerline of a vehicle, the first section and a second section being on opposite sides of a pulley and parallel to the centerlines of the vehicle and cart;
connecting the vehicle to the second section of the cable; and
pulling the cable about the pulley to impact the vehicle and the cart while centerlines are offset.

18. The method as set forth in claim 17 , wherein the cable extends about a motor with the first and second sections on opposite sides of the motor, further comprising turning the motor to pull the cable about the pulley.

19. The method as set forth in claim 17 , further comprising releasing the vehicle from the cable prior to impacting the vehicle and the cart.

20. A system, comprising:
a rail;
a cable moveable along the rail;
a shuttle fixed to the cable and slideably coupled to the rail;
a cart having a connector horizontally spaced from the rail and a centerline parallel to and horizontally spaced from the rail;
an arm fixed to the shuttle and extending from the shuttle to the connector, the arm being releasably connectable to the connector; and
a second shuttle fixed to the cable and slideably coupled to the rail, the shuttle and the second shuttle slideable along the rail in a direction toward each other.
