【Abstract】 By analyzing and comparing with some design schemes about structural lock of peripheral docking system, the efficient transmission mechanism for the screw of ball bearing is selected as the executive mechanism of structural lock. Its dynamic model is built and analyzed. The SIMULINK module is used to solve and analyze the dynamic model, and the dynamic characteristics of structure lock are obtained. The research indicates that design scheme presented is feasible.更多还原
