摘要
车架是重型载货汽车的重要组成部分,支撑和连接汽车的各总成和重要零部件,承受各种力和力矩,因此车架的强度对整车的安全性有着重要的影响。文章通过有限元分析软件建立车架的有限元模型,并对其进行强度和刚度的有限元极限工况分析计算,根据分析结果找到车架的薄弱环节,针对薄弱环节提出优化方案并改进。分析结果表明优化后车架的强度和抵抗变形的能力都有所增强。
The frame,an important part of a heavy-duty truck,supports the assembly and the important parts of a car and bearsall kinds of forces and torques.So,the strength of the frame has a great influence on the safety of the vehicle.Therefore,this paperwill firstly use the finite element analysis method to establish the finite element model of the frame and then analyze the strength ofthe frame in the extreme conditions in order to find its weakness.Finally,according to the analysis’results,the paper will propose anoptimization scheme to improve the frame.And the analysis shows that the optimized frame has a better capacity in the strength andthe resistance to deformation.
