ABSTRACT:
A mechanical tire emulator for spindle coupled road simulators. It simulates the real case tire impedance characteristics, including wheel hop, between the servo actuator produced vertical road input motion and the vehicle spindle. By simulating the loading impedance of the tire using a fluid pressure actuator loading through a compressible fluid cushion and substituting this actuator device for the rigid vertical link on prior art spindle coupled road simulators, the overall mounting arrangement is simplified over that when a tire itself is mounted on a wheel for such testing.
