“…In the processing and assembly of the rotor, there are inevitable error factors, which make the rotor imbalanced. Although the rotor will be dynamically balanced before space application, the imbalanced mass cannot be completely eliminated [20]. Therefore, the imbalance disturbance excitation appears along with the high-speed rotation of the rotor.…”

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.
