摘　　要：为解决飞轮系统中因轴承摩擦导致的能量损耗问题,设计了一种可以应用于飞轮系统的径向永磁轴承。分别利用Yonnet简化数学模型和有限元分析软件ANSYS Workbench,对轴承中的磁环进行了承载能力的计算和分析。结果表明,磁环所受径向力随磁环厚度、径向偏移量增加而增加,但其增加关系有所不同;另外,随着轴向偏移的增大,径向力逐渐减小、轴向力迅速增大。In order to solve the energy - loss problem in flywheel system caused by bearings＇ friction, this article introduces a design of radial permanent magnetic bearings using in flywheel system. And with the help of the Yonnet simplified mathematical model and CAE software ANSYS Workbench, we calculate and analyze the carrying capacity of magnetic rings in the bearings. The re- sult shows that the radial force increases with the increase of thickness and radial offset of the mag- netic rings in different manners. Moreover, the ra- dial force decreases fast with the axial offset^s in- crease of the rings while the axial force increases with it.
