Research on multi-degree of freedom force loading system based on parallel mechanism

During the on orbit working process of space station, the docking mechanisms play a very important role. The docking mechanisms bear multi-degree of freedom directions force and torque on the long time on-orbit running. So the multi degree of freedom force and torque fatigue test experiment is necessary for the design and test of docking mechanisms. A multiple-degree of freedom force and torque loading system based on parallel mechanism was designed to accomplish the fatigue testing efforts.
