摘　　要：受静力和动力影响,电动叉车轮边减速器壳体易造成变形失效和振动疲劳失效等问题。因此,使用ANSYS有限元分析软件对减速器壳体分别进行静力学分析和动力学谐响应分析。研究发现,当满载工况条件下,壳体轴承内圈中下部发生明显变形,采用增加轴承壁厚方法对内圈中下部风险位置进行优化,能使壳体力学性能满足使用要求;当激励频率为2669.5 Hz时,壳体下群部力学性能较差,寿命较短,采用减少下群部预留孔数量的方法对下群部风险位置进行优化,能改进壳体力学性能,延长壳体的使用寿命。The wheel rim retarder housing of electric forklift is affected by static force and dynamic force,which causes the failures like housing deformation and vibration fatigue.Therefore,the static analysis and dynamic harmonic response analysis of the retarder housing are carried out by using ANSYS finite element analysis software.Study shows that the lower part of the inner ring of the housing bearing is obviously deformed under full load condition.The risky position in the lower part of the inner ring is optimized by increasing the thickness of the bearing wall.The mechanical properties of the housing after improvement meet the application requirements.When the excitation frequency reaches 2669.5 Hz,the mechanical properties and service life of the lower part of the housing are at a low level.The risky position in the lower part of the housing is optimized by reducing the number of reserved holes in the lower part,which can significantly improve the mechanical properties and service life of the housing.
