中文摘要：

随着近年美、德、日等国研究小组的大容量高温超导飞轮储能系统（HTSFESS）样机的报道，具有控制简单、储能密度大、效率高、寿命长、应用范围广等优点的HTSFESS已经被广泛认可。综合主要研究小组的工作发现，采用高温超导磁悬浮轴承与永磁轴承配合的结构在保证飞轮转子轴向和径向都稳定的同时，具有成本低的优势。针对这种混合轴承布置方式，文中对超导飞轮储能用永磁轴承的承载能力进行了研究，通过有限元仿真分析提出了一种径向型永磁轴承的优化方案，相关结果可为后续样机研究提供一定的参考。

英文摘要：

With successive reports on the large - scale high temperature superconducting flywheel energy storage system （HTS FESS） prototypes, the advantages of simple control, high energy density, high efficiency, long service life, wide applica- tion range and so on have been widely acknowledged in recent years. By analyzing the prototype work of main groups in USA, Germany, Japan and South Korea, the hybrid beating system composed of superconducting magnetic bearing （SMB） and perma- nent magnetic bearing （PMB） is found to be able to keep the same stability as double SMB system in both radial and axial direc- tions but with lower costs. From this point we investigated the load capability of the PMB. Some key structure parameters were optimized by FEM simulation analysis. The results will provide some references for the following HTS FESS prototype research.
