Abstract

In the assembly missions of spacecraft, the cabins docking are the final part of the product assembly to form the probe into a whole, which is one of the most critical parts of the assembly task. The spacecraft of Insertion and Containment in cabin docking faces difficulties such as eccentricity of mass, small safety spacing, and non-visibility. In this paper, interference detection method based on reverse engineering non-contact virtual assembly and precision docking process method with tiny spacing of cabin eccentricity were proposed, and a large eccentric inline cabin docking device was developed to solve the problem of inline cabin precision docking. The above-mentioned method was applied to achieve nearly 100 successful dockings during the AIT process, which ensured the success of the spacecraft mission.
