摘　　要：利用有限元法对轴向电磁轴承的磁场分布进行了数值模拟分析,并通过对某一实际电磁轴承的轴向轴承磁场分布及电磁力的分析计算,得出了轴向电磁轴承的承载力工作范围和静态刚度曲线,所得结果可作为轴向电磁轴承实际设计的准则。The numerical simulation analysis on magnetic field distribution of axial electromagnetic bearing has been made using finite element method. According to the analysis results of electromagnetic field distribution and calculation of electromagnetic forces for an practical axial electromagnetic bearing, the main parameters such as load - carrying capacity range and stiffness curve of the electromagnetic bearing are obtained. The results provide a guide to the design of the axial electromagnetic bearing.
