万向磁悬浮动量轮研究

目前大部分空间飞行器三轴姿态控制采用的是飞轮系统，其精度较高，而采用磁悬浮轴承支承的动量轮比普通的滚珠轴承动量轮有更高的姿控性能。在此基础上发展的动量矩方向可改变的万向磁悬浮动量轮可以单独实现三轴较高精度的主动姿态控制，具有重要的实用价值。同时，万向磁悬浮动量轮的研究也为集成能源与姿态控制系统的研究提供了技术支持。文意介绍了万向磁悬浮动量轮在国际上研究和发展的情况，概括了其中的关键技术，并给出了一种初步的结构设计实例。

Study for Gimbal Magnetic Suspension Momentum Wheel

Fly wheel system is widely used in majority of spacecrafts to control three axes attitude recently. Its precision is higher than that of small thruster system. But the magnetic suspension momentum wheel has better performance than the conventional ball bearing momentum wheel in spacecraft attitude control. The gimbal magnetic suspension momentum wheel developed from the ordinary one can adjust the angular orientation of its spin axis and complete three axes attitude control in high precision separately, which has great value in practice. Simultaneously, the study for gimbal magnetic suspension momentum wheel can benefit the integrated power and attitude control system technologically. This paper describes the research status and development of the gimbal magnetic suspension momentum wheel in detail. Then the key technologies are analyzed. Finally the example of structure design is introduced.
