Design and Verification of Rotating Avoiding Type Locking-Releasing Mechanism

Given the resistance environment and rotation requirements of the satellite payload module, a horseshoe-shaped compression slider bearing method and a double-layer structure shear resistance method are proposed. A rotating avoiding type locking-releasing mechanism is designed, which has a large bearing capacity and reliable locking, and can leave a sufficient rotation avoidance gap for the payload module after release. Then, the analysis and design process of preload is given, and the axial tensile and transverse shear tests are carried out to verify the reasonableness and feasibility of the designing scheme, which solved the technical problem of rotating operation of the 2-ton payload module after enduring the harsh mechanical environment effectively, and can be applied to the task of locking and releasing the same kind of rotating type payload in the resistance environment.
