Micro-vibration data processing method for large space payloads
摘要
Abstract
To address the challenge of multi-sensor data transformation and synthesis in ground-based micro-vibration testing of large space payloads,an algorithm for micro-vibration data processing was proposed based on the testing of the coronagraph payload of the Chinese Space Station Telescope(CSST).The algorithm used a simple coordinate transformation to convert multi-sensor measurement data at the interface between the coronagraph payload and the satellite from the sensor's local coordinate systems to a common reference frame.Utilizing the transformed sensor data as input,the algorithm then applied spatial force synthesis theory to calculate the six-component force and moment(Fx,Fy,Fz,Mx,My,Mz)at the payload's center of mass.To verify the effectiveness of the spatial force synthesis theory used in the algorithm,a simplified force measurement platform with four sensors was constructed and compared with a calibrated force measurement platform,both measuring the same vibration source.The results show that the relative root-mean-square(RMS)error of the three-axis forces is within 4%,and the RMS error of the three-axis moments is within 8%.This algorithm can be used for data processing in micro-vibration testing of large space payloads and serves as a tool for guiding and validating micro-vibration isolation design.关键词
