摘　　要：汽车动力总成悬置系统的设计应满足支撑作用,合理的悬置静刚度能够抵抗静载荷作用下的结构变形。为了研究悬置静刚度特性,利用Catia软件对某乘用车的悬置建立三维模型,通过Hypermesh对模型进行六面体网格划分,将网格文件导入Abaqus进行有限元分析后处理。基于橡胶静刚度求解公式,拟合支座反力与位移函数求得橡胶衬套在X、Y、Z三向的静刚度数值,为橡胶衬套结构设计与优化提供了数据参考。结果显示,前悬置橡胶衬套在Y向的静刚度数值最大。The design of automotive powertrain mounting system should meet the support function,reasonable static stiffness of mounting can resist the structural deformation under static load.In order to study the static stiffness characteristics of the suspension,Catia software was used to build a three-dimensional model of the suspension of a passenger car,and the model was divided into hexahedral mesh through Hypermesh.The mesh file was imported into Abaqus for finite element analysis and post-processing.Based on the solution formula of the rubber static stiffness,the static stiffness values of the rubber bushing in the X,Y and Z directions were obtained by fitting the reaction force and displacement function of the bearing,which provided a data reference for the structural design and optimization of the rubber bushing.The results show that the front mounted rubber bushing has the maximum static stiffness in the Y direction.
