摘要为了实现板式电涡流阻尼器的精确、高效和优化设计，首先以某一电涡流调谐质量阻尼器为计算模型，验证了采用三维电磁场有限元稳态分析方法计算板式电涡流阻尼器阻尼系数的准确性。然后利用三维磁场有限元稳态分析方法，分析了板式电涡流阻尼器的各设计参数对阻尼比的影响。结果表明，三维磁场有限元稳态分析方法能够准确计算板式电涡流阻尼器的阻尼系数；导体板厚度、导磁钢板厚度、永磁体间距、空气间隙和永磁体的排列方式对板式电涡流阻尼器的阻尼性能影响显著，在设计中应综合考虑。

Abstract：To achieve the precise, effective and optimal design, an eddy current TMD is selected as the calculation model. The accuracy of the 3D static electromagnetic finite element analysis method in calculating the damping ratio of a planar eddy current damper is verified. Then the effect on the damping ratio of each design parameter of a planar eddy current damper is analyzed, using this method. The result shows, that the 3D static electromagnetic finite element analysis method can accurately calculate the damping ratio of a planar eddy current damper. Some parameters have great effects on the damping capacity of a planar eddy current damper, such as the thickness of conduct plates, the thickness of steel plates, the distance between magnets, the distance between magnets and conduct plates and the orientation of magnets. These parameters should be fully considered during the design.

Key words： eddy current damping electromagnetic field parameter analysis finite element method (FEM) permanent magnets
