摘要

分析了抑制卫星飞轮振动的方法，提出了隔振为主、吸振为辅的联合减振方案。研究了会聚式隔振系统参数对其减振性能的影响；针对会聚式隔振系统存在的不足，提出了圆周分布式吸振方法和相应的吸振系统，分析表明会聚式隔振系统在4个方向的隔振效率达90%以上。根据会聚式隔振系统在

平动方向隔振效率较低的问题，建立了会聚式隔振和圆周分布式吸振的联合减振系统仿真模型。仿真结果表明，联合减振系统较单纯的隔振系统在

平动方向减振效率提高近50%，且不改变其他方向的减振性能。因此，联合减振设计方法合理可行，适用于卫星飞轮等主要振源的振动抑制，并为飞轮联合减振系统的工程化设计提供了理论支持。

Abstract

The methods to reduce the vibration of a satellite flywheel were analyzed

and a joint vibration reduction scheme was proposed by combined vibration isolation and vibration absorbing. The effect of the parameters of assembled isolators on its vibration reduction was researched. According to the shortcomings of the system

the circumferential distributed absorbing method and a corresponding system were proposed to reduce the vibration of the flywheel. The simulation shows that the vibration response of main structure subjected to external force dissipates by 90% in all directions except

direction. Then

circumferential distributed absorbers were designed to improve the performance of assembled isolators in

direction

and a simulation model of the joint vibration reduction was also established. Compared with unsophisticated isolators

the conclusion indicates that the performance of the joint vibration reduction is nearly improved 50% in

direction. Consequently

the joint vibration reduction scheme is suitable for reducing the vibration response of flywheel and is proved to be effective and practical in the vibration control for other vibration sources in satellites.
