Research on Measurement Method of Mechanical Environment of Satellite-rocket Separation

The measuring method on launch vehicle flight′s mechanical environment with real-time, high-precision and low occupancy rate of resources is researched, especially under the complex mechanical environment of satellite-rocket separation, a novel presetting control method is proposed to realize the reuse of measurement resource on shock and noise. The traditional ground processing mode on shock and noise measuring is fully compared with our method and the difference is fully analyzed. The results show this novel method has good performance and provides valuable reference to the engineering application.
