Abstract:

As the core of the entire spacecraft Prognostic and Health Management (PHM), the spacecraft ground PHM system mainly provides spacecraft technicians with services such as data analysis, diagnosis, and prediction in the process of spacecraft testing, operation and management. At present, due to the difficulty in obtaining the spacecraft failure mechanism, insufficient failure verification environment, and lack of unified verification methods and performance indicators, it is difficult to effectively verify and evaluate the research results of spacecraft PHM. A design idea of a spacecraft ground PHM system based on big data is proposed, and the index system of the PHM system verification and verification methods are studied. On this basis, the spacecraft ground PHM verification system based on simulation and experimental verification is designed and realized. The multiple spacecraft fault simulations and on-orbit historical data tests verified the effectiveness of the proposed ground PHM verification system design method, which can be effectively applied to the spacecraft ground health management process, and has strong practical significance in the field of the spacecraft engineering application..
