摘要
针对某车型发动机正时罩盖在道路试验中的断裂失效问题,采用有限元方法进行疲劳强度分析,发现疲劳结果与试验失效位置一致。根据分析结果,优化正时罩盖的结构设计,从而解决了失效问题。
Aiming at the fracture failure of engine timing cover during vehicle test,the finite element method was used to analyze the fatigue strength,the result was consistent with the test result.According to the analysis result,the structural design of the timing cover is optimized,and the failure risk are removed.
