The docking dynamics test platform uses semi-physical simulation method to simulate docking dynamics processes of two space aerocrafts. Appling EASY5 and ADAMS this article has established the docking dynamics test platform simulation model. It includes machinery dynamics model, aerocrafts docking dynamics resolving, trajectory planning and motion simulator position posture counter-solution and hydraulic servo cylinder model. The combination initial deviation docking simulation result has confirmed that the test platform mathematical model is correct. The precision test simulation result has demonstrated the major effects of precision. As a simulation platform, this model has provided important reference for designing and debugging.
