Abstract:

A restraint and guidance system for testing vehicles has members on opposite sides of the vehicle which are secured to the vehicle, and a linkage member that permits the vehicle to move freely in the vertical, roll and pitch directions but which restrains movement in logitudinal direction of the vehicle. This permits the vehicle to move vertically freely, and to be rolled and pitched as guided by linkages that are completely decoupled from each other. The restraint system can be connected to actuators for controlling lateral loads. The kinematic paths of the linkage for reacting the loads are the same as if the vehicle body was inertially restrained, that is, acutaly moving in space during testing.
