摘要
基于卫星飞轮的静动不平衡原理,对飞轮的静动不平衡进行了建模。根据建立的整星动力学模型进行了仿真分析。结果表明:飞轮的静不平衡对整星的扰动较动不平衡大2个量级,是主要的颤振激励源。
The models of static and dynamic unbalance of flywheel were established based on the principle of the static and dynamic unbalance of satellite in this paper. The simulation was made according to the models set up. The results showed that the static unhalance was 2 orders more than the dynamic unbalance for the flywheel, which was the major jitter source.
