Design and Simulation Analysis of Docking Interface of Linked In-Orbit Replacement Module

On-orbit service for spacecraft relies heavily on on-orbit docking with the orbital replacement unit interface. Foreign research interface of orbit replaceable has been in-depth, while domestic work is still limited. Currently, most design axial feed manipulator, which may result in insufficient mating force under specific conditions. In view above problems, it requires a linear plug-in locking unit, and scheme tapered rod guide linkage parts needs to be determined. Optimization mechanism completed by finite element simulation. The effect clearance taper rod, effective points friction coefficient have analyzed means dynamics modelling during processes. also verified rationality linkage. A processing path verification prototype made as well. This introduces idea self-plugging process. It lays foundation development control strategy unit.
