摘　　要：车架是卡车的重要零部件,承载着汽车的大部分载荷,车架可靠性直接关系到整车性能。为解决载货车横梁连接板开裂问题,通过建立载货汽车车架有限元模型,利用有限元方法,计算分析车架刚度、强度,提出改进优化方案,有效解决横梁连接板开裂问题。Frame is the important parts of trucks,and It carries most of the load of the trucks.its reliability is associated with the vehicle product quality.Aiming at the connection plate cracking problem,a detail FEA is model of the truck frame is built,using finite element method analysis stiffness and stress of the frame,an improvemeng scheme was proposed,and finally the cracking problem is successfully solved.

关 键 词：车架 连接板 开裂 有限元法
