摘要
针对某车型垂直道路模拟疲劳试验报告里记录的车身焊点开裂问题,从结构、材料方面进行分析,并给出了解决措施,通过CAE仿真计算对比分析验证了改进方案的可行性。其接头处焊点开裂、悬架安装点处焊点开裂及焊接边过窄造成的焊点开裂都是车身设计中经常出现的共性问题,其分析、解决问题的方法具有为后续车身开发设计提供参考和指导作用。
For the problem record of car body spot craze in fatigue bench test report, this paper is presented the reason analysis from structure, material aspect, and presented the resolver measure. The feasibility of improvement scheme is validated on contrast analysis of CAE simulation computation. The spot craze of the joint, the suspension fixure, and the smallness jointing edge, those were often occurred, the common problem in course of car body designing. The method of analysis and resolve problem can provide reference and direction for latter car body design.
