Ground Measurement and Signal Estimation for Micro-vibration of Quantum Science Experimental Satellite
摘要
Abstract
In this paper,micro-vibration measurement and signal estimation on the Quantum Science Experimental Satellite ground test is introduced.Based on the technology requirement of the satellite,the method of measurement is determined to detect the vibration of high-accuracy optical payloads when the oscillation source comes from on-board rotatable instruments,such as reaction wheel installed in the satellite body.The characteristics of vibration transfer from a vibration source to sensitive points are estimated,and vibration displacement and angular oscillation are approximated by applying an integration wavelet.The validation of the proposed method is confirmed by experimental test,and the result is of interest in ground test of micro-vibration for Quantum Science Experimental satellite with high accuracy payloads.关键词
