摘　　要：实现减速器壳体轻量化设计是节约成本、减轻能耗的有效途径。文中通过对二级减速器壳体原始设计进行静力学有限元分析,发现减速器壳体的静强度和安全系数远远小于许用值,导致材料严重浪费。在此基础上基于机械优化设计理论,采用几何优化设计方法,以减速器壳体壁厚、加强筋厚度以及上下凸台的壁厚为设计变量,以减速器壳体质量最小为优化目标,利用UGNX仿真环境对减速器壳体进行优化仿真计算。经过优化后,减速器壳体质量减轻了24.54%。此研究结果为轻量化设计提供了理论参考。The lightweight design of reducer housing is an effective way to save cost and reduce energy consumption.In this paper,through the static finite element analysis on the original design of the secondary reducer shell,it is found that the static strength and safety factor of the reducer shell are far less than the allowable value,resulting in serious waste of materials.On this basis,based on the mechanical optimization design theory,the geometric optimization design method is adopted,and the UGNX simulation environment is used to carry out the optimum simulation calculation of the reducer shell.The wall thickness of the reducer shell,thickness of the stiffener and the wall thickness of the upper and lower bosses are taken as the design variables,and the minimum weight of the reducer shell is taken as the optimization objective;after optimization,the weight of the reducer housing is reduced by 24.54%.This research conclusion provides a theoretical reference for lightweight design.
