摘　　要：在建立三维装配实体的基础上,建立了三环减速器齿环部件的有限元模型,采用Lanczos法对齿环部件进行了动特性分析。在建模中对实际约束条件进行合理简化,并对关键零件的接触问题做了处理。动态分析得到了其固有频率和振型,显示了齿环部件的弯曲、扭转及其耦合振动特性。结果表明三环减速器齿环部件的模态密集,频率范围很宽,振型复杂,为三环减速器的结构改进及整机的动态响应分析提供了理论依据。The FEM model of three - ring gear reducer is built based on the established 3D assembly model. The dynamic characteristic analysis is carried out by using the Lanczos method. The actual restrictions and contact areas of key parts is reasonable simplification in model construct. The problem of key component is processed. Through the dy- namic analysis, the natural frequency and vibration are obtained, the bend, torsion and coupling vibration characteristics of the ring plate component are showed. The result indicates that the system has dense modal, wide frequency rang and complex vibration modes.
