Evolution of the spacecraft mechanical environment predication & test technology

The spacecraft mechanical environment is the response description of spacecraft subjected to various loads during the mission process. It is the key factor that directly affects the design of spacecraft and dominates the suceess /failure of the flight mission. The spacecraft mechanical environments mainly include the mechanical environment of the launching process and that on orbit acoording to phases of the mission. With the development of spacecraft engineering, the harsh requirements of the spacecraft payloads to the mechanical environment are becoming more and more urgent, its analysis and test technology has become the key factor restricting the development of spacecraft. In this paper, the research on the mechanical environment analysis technology of the launching process, the micro vibration environment on orbit, the mechanical environment test technology and the spacecraft vibration control technology are reviewed respectively in four apects, and their evolution and achievement are summarized and discussed. In the end, based on the actual requirements of space engineering and the development trend of the spacecraft, the future research directions of mechanical environment prediction and test technology are pointed out.
