Other AbstractAn APM was consisted of two orthogonal joints.To test the performances of APMs, a hierarchical and simultaneous gravity unloading method was proposed, and a gravity unloading testbed was built based on this method.The gravity of two orthogonal joints were unloaded and the rotational degree of freedom for both joints was offered by the air bearing gravity unloading testbed.The testbed Was a two layers structure, and the combination of planar air bearing and air spindle was used to unload gravity, Which provided the two degrees of freedom to allow the rotation of APM.The payload test might truly show the performance of APMs, so the artificial payload was designed with the constraints of moment of inertia and frequency.This artificial payload was fixed on the gravity unloading testbed. The coupling problems of moment of inertia of both axes were solved and the frequency requirements were satisfied. The gravity unloading testbed was established and tested based on the analysis of gravity unloading method and design of the artificial payload. The testing results show the effectiveness of the hierarchical and simultaneous gravity unloading method.
