摘要
Since spacecraft faces complicated mechanical environment which poses a great threat to the structure and sensitive equipment during flight missions, vibration measurement is always a focus for spacecraft design. In the recent remote sensing and space experimental missions, vibration environment during the launch period and micro-vibration environment while spacecraft operating in-orbit was measured and analyzed massively. A lot of flight data has been acquired. In this work, constructions, functions and technical index of monitoring and measurement systems installed on spacecraft are introduced. Applications of measured data during launch and in-orbit period are discussed respectively. Measured data during the launch period can be used to optimize mechanical testing conditions. Difference of the measured micro-acceleration between on ground and in-orbit is found. The measured data helps a lot at modification of mechanical testing conditions, adjustment of mechanical model and monitoring of micro-vibration environment. Future development of the measurement system is proposed in the end of this paper.
