Abstract
A roadway simulator restraint system supports a vehicle at each of its wheels on simulated roadways which comprise endless belts suitably driven to cause wheel rotation. A plurality of passive links are provided for restraining the vehicle in longitudinal, lateral, and yaw degrees of freedom, while permitting free motion in roll and pitch moments, and vertical directions. Additionally, the linkages can provide inputs in aerodynamic force directions to simulate responses to vehicle dynamics during actual operation. The individual roadways that support the wheels can be independently controlled as to speed, and can be turned. Suitable force measurements are made in desired axes to provide for a complete controlled simulation of vehicle operation on an actual roadway.
