概要
It is very important to ensure the reliability of ground environmental test facilities for spacecraft in testing, because non-conformances of those facilities can have a serious impact on the cost for spacecraft developments due to schedule delay. Ground environmental test facilities of JAXA have been provided with preventive maintenance to eliminate the risks of non-conformances during tests. Meanwhile, recent facility maintenance technology is now becoming more efficient with the application of risk-based maintenance, including a condition monitoring maintenance based on IoT technology which has been attracting much attention. In this paper, the results of quantitative assessment on the Weibull analysis for the maintenance of ground environmental test facilities and the issues specific to the maintenance of those facilities will be reported.
