Technology of Satellite Segment Vibration Test
摘要
Abstract
Vibration test technology of satellite segments was studied. Based on minimizing the accumulative relative errors of the amplitudes of the acceleration response at the testing points between entire satellite vibration test and segment vibration test, the algorithm for solving the input acceleration spectrum for the satellite segment vibration test was derived. Vibration tests were carried out for the entire satellite and its segments with this algorithm. The results show a good coinci-dence between the tests and the theoretical computation. It is concluded that the response difference between the entire satel-lite test and the segment test depends on their dynamical characteristics. The presented algorithm can ensure that the segment response is the best approximation of the entirety response of the satellite.关键词
