ABSTRACT:
A test system for testing axles and wheel spindles directly in place on vehicles such as automobiles, which simplifies the loading to obtain the necessary information for testing axles and spindles using two sets of actuators, each set comprising a pair of actuators each operating to control loads on the spindle along two different orthogonal components of normal movement of the vehicle. The actuator arrangement saves space, permits testing without removing automotive sheet metal and simplifies the compensation factors necessary for controlling such systems.
