摘　　要：在冷热冲击试验过程中,某发动机第五主轴承盖发生断裂失效.针对该问题,基于Abaqus对主轴承盖组件进行有限元分析,结果表明其断裂处疲劳安全因数低于经验值;对主轴承盖进行优化设计,并运用同样的仿真方法得到疲劳分析结果.经过反复验证,得到主轴承盖最优设计方案,并通过试验验证解决该主轴承盖断裂问题.The fifth main bearing cap of an engine is fractured during the thermal shock test. So the finite element analysis of the main bearing cap is performed by Abaqus. The result shows that the safety factor is less than the limit value. After optimizing the main bearing cap structure time and again, the best project is tested, which could solve the fracture problem.
