“…Practical application results showed that the model can describe the typical behavior of a series of micro-vibration sources of an RWA, and predict the worst case accurately with only a limited number of devices considered. Based on the measured data of disturbing forces and torques in a certain frequency band, Hur and Kim [109] proposed a hybrid model. The accuracy of the proposed model was verified by comparing the predicted results with the measured PSD function of the RWA.…”

In this paper, the main excitation sources of micro vibration of spacecraft flywheel rotor systems (SFRSs) are briefly described, and then the research progress is systematically reviewed from four perspectives, including modeling methods, suppression means, vibration isolation techniques, and ground simulation tests. Finally, the existing problems of current research and the direction of further research are given to better serve the micro-vibration prediction and sensitivity analysis of existing models, and provide reference points for the micro-vibration suppression and isolation of the next generation of high-precision spacecraft.
