Abstract: The design method of the vacuum leak testing management system for spacecraft components is discussed in this paper. The vacuum leak testing management system for spacecraft components is an essential subsystem of the special environment test management system for spacecraft components. According to the requirements of the vacuum leak testing management system for spacecraft components and the software development process, the test processes are analyzed and the overall structure and various functionality modules are designed. The testing management system is divided into three mutually supporting levels: the user service tier, the business logic tier and the data resources tier. There are seven functional modules in the spacecraft component vacuum leak testing management system, including the test task management, the personal task management, the test data management, the test file management, the test resource management, the configuration management and the system management. This system would be helpful to a more efficient and reasonable management of vacuum leak testing for spacecraft components.
