Abstract:

On-orbit maintainability is one of the most important methods to extend the lifecycle of the space station, as it ensures the safety of astronauts and minimizes operating costs. Based on this, maintainability verification plays an extremely significant role in on-orbit maintenance and can verify the correctness and validity of the on-orbit maintainability. By conducting a comparative analysis and reviewing best practices both at home and abroad, this paper embarks on the mission of the China manned space station, combined with the requirements of objects, test items, and environment that need to be verified. The authors propose a ground testing by-step classification methodology and a simplified zero-gravity simulation separated space platform to accommodate the validation of the entire process on the orbital replaceable units.
