摘要：建立Halbach永磁电磁阻尼器和表面径向永磁电磁阻尼器的有限元分析模型，对这两种结构形式的电磁阻尼器的磁场特性、力矩特性和涡流损耗进行了有限元仿真,得到了Halbach永磁电磁阻尼器和表面径向永磁电磁阻尼器的磁场分布、力矩时间曲线、涡流损耗时间曲线等关键特性曲线。对比分析结果表明，Halbach永磁电磁阻尼器和表贴径向永磁电磁阻尼器，在磁路特性和力矩特性上存在较大差异，并得出了相关结论，为电磁阻尼器的设计提供参考依据。

Abstract: The finite element model of Halbach permanent magnet electromagnetic damping machine with radial structure permanent magnet electromagnetic damping machine were built based on ansoft Maxwell .The magnet field, torque, eddy current loss were analysed.The analysis show that there were some difference in Halbach permanent magnet electromagnetic damping machine with radial structure permanent magnet electromagnetic damping machine .The analysis result also provided a reference for electromagnetic damping machine.
Key words: damping machine; arrangement of Halbach magnet ;surface permanent magnet
