摘　　要：磁悬浮轴承已在高速飞轮储能和旋转机械等重要领域得到广泛应用。系统研究了高速飞轮储能用永磁悬浮、电磁悬浮、超导悬浮和混合悬浮轴承的工作原理、结构型式和特点,分析了各种磁悬浮轴承的悬浮力、刚度,并介绍了国内外研究现状以及待解决的关键技术问题,阐述了未来发展趋势。Magnetic suspension bearings have been widely used in high - speed rotating flywheel energy storage, rotating machinery and other important fields. The principles, structure, and characteristics of different magnetic bearings, such as the permanent - magnetic bearings, electromagnetic bearings, superconducting magnetic bearings and magnetic beatings used in high - speed flywheel storage were discussed. In addition, the levitation force and rigidity of magnetic bearings were analyzed, the re- search status of magnetic bearings at home and abroad, key technical issues and direction of development were introduced.
