【摘要】：针对某车型副车架在台架试验过程中出现开裂问题,采用有限元分析软件Hypermesh建立副车架有限元模型,分析了其强度和模态,结果发现疲劳试验时车架开裂的位置与有限元分析的基本相同,并提出结构改进措施,改进后的副车架有限元分析应力明显降低且通过了疲劳台架试验。
[Abstract]:In view of the cracking problem of the subframe of a vehicle model during the bench test, the finite element model of the sub-frame is established by using the finite element analysis software HyperMesh, and its strength and mode are analyzed. The results show that the crack position of frame in fatigue test is basically the same as that of finite element analysis, and the structural improvement measures are put forward. The stress of the improved finite element analysis of the sub-frame is obviously reduced and the fatigue test is carried out.
