摘　　要：针对联合工况下带加强肋的轮边减速器箱体,建立其有限元模型,分析其载荷边界条件,对其进行静力分析,并得到有限元分析结果.在此基础上,优化箱体上存在的应力集中以及加强肋的厚度和类型.优化后的箱体较原箱体减轻4.25%.观察优化后箱体的应力分布,发现这种轻量化设计方法合理且对带肋箱体的优化设计具有借鉴意义.Under combined working conditions,a finite element model is first established for ribbed wheelrim reducer cases.Then,the loading boundary conditions,together with static dynamics,are analyzed to obtain the finite element analysis results.Next,the case stress concentration,along with rib thickness and type,is optimized to reduce the case weight by 4.25%.Finally,it is found from observations on the optimized case stress concentration that the lightweight design method,which sets a reference to optimization design,is rationale.
