摘　　要：传动轴是汽车传递系统的重要组成部分。凸缘叉是传动轴上的凸缘结构,用于连接和传递动力的传动装置,在传动轴中有着重要作用,因此有必要对汽车传动轴的凸缘叉进行结构、材料优化设计和分析。先根据实际需求设计凸缘叉,再通过SolidWorks软件建立三维模型,Ansys Workbench软件进行静力学分析,得到等效应力云图和变形量云图,通过云图判断凸缘叉薄弱点,判断模型的准确性。后对凸缘叉进行结构拓扑优化分析,根据分析结果对凸缘叉的结构形状进行尺寸优化,并对优化后的凸缘叉进行疲劳寿命分析,疲劳寿命云图显示拓扑优化后的凸缘叉符合标准,运用钛材作为材料能有效优化凸缘叉21.3%的最大应力,减轻凸缘叉40.9%的质量。研究结果可为传动轴中凸缘叉设计提供更多可能性。Transmission shaft is an important part of automobile transmission system.The flange fork is a flange structure on the transmission shaft,which is used to connect and transmit power.It plays an important role in the transmission shaft.Therefore,it is necessary to optimize the structure and material of the flange fork of the automobile transmission shaft.Design and analysis.Firstly,the flange fork is designed according to the actual demand,and then the three-dimensional model is established by SolidWorks software.The static analysis is carried out by Ansys Workbench software,and the equivalent stress cloud map and deformation cloud map are obtained.The weak points of the flange fork are judged by the cloud map,and the accuracy of the model is judged.Then,the structural topology optimization analysis of the flange fork is carried out.According to the analysis results,the structure shape of the flange fork is optimized,and the fatigue life analysis of the optimized flange fork is carried out.The fatigue life cloud diagram shows that the flange fork after topology optimization meets the standard.The use of titanium as a material can effectively optimize the maximum stress of the flange fork by 21.3%and reduce the mass of the flange fork by 40.9%.Through this study,more possibilities are provided for the design of the flange fork in the drive shaft.
