摘要:

为研究具有径向与轴向磁路的混合式永磁调速器导体转子对混合式永磁调速器振动影响,首先,建立混合式永磁调速器转子仿真模型,分析混合式永磁调速器振动原因;其次,以Donnell壳体理论为基础建立了混合式永磁调速器导体转子模型;最后,采用有限元软件完成对永磁调速导体转子的振动仿真分析。研究结果表明:轴向与径向导体转子的厚度差值越大,导体转子振动效果越差;径向导体转子对轴向导体转子具有抑制振动的作用;导体转子振动效果与其厚径比成正比,与长径比成反比。

Abstract:

In order to study the effect of the conductor rotor of a hybrid PMG with radial and axial magnetic circuits on the vibration of the hybrid PMG, firstly, a rotor simulation model of the hybrid permanent magnet governor was established and the vibration reasons of the hybrid permanent magnet governor were analyzed. Secondly, based on Donnell's shell theory, a hybrid PMG conductor rotor model was established. Finally, finite element software was used to complete the vibration simulation analysis of the PMG conductor rotor. The results show that the higher the thickness difference between the axial and radial conductor rotors, the worse the vibration effect of the conductor rotors. The radial conductor rotor can suppress the vibration of the axial conductor rotor. The vibration effect of the conductor rotor is proportional to the thick-diameter ratio and inversely proportional to the length-diameter ratio.

Key words: hybrid permanent magnet governor, finite element modal analysis, Donnell shell theory
