Spacecraft docking technology play an important role in the aerospace technology. Due to the spacecraft with variable attitude, so the docking process is complex and variable. Therefore, a comprehensive and systematic study of the spacecraft docking process is very necessary. This paper proposed the equivalent-mass principle and the test platform of spacecraft docking is established based on the equivalent-mass principle through the analysis of environmental characteristics of thermal vacuum. Furthermore, dynamic simulation on the test platform and the results data of simulation is obtained. These studies will facilitate the understanding of the spacecraft docking process and provide solid theoretical foundation for further study.
