| Abstract: | Taking the fatigue durability design of engine cylinder head as the research object, the fatigue tests of cylinder head materials under different temperatures are carried out, and the detailed material characteristic of high and low cycle fatigue are obtained. Combined with the CAE fatigue analysis method and theory, the temperature field simulation, high cycle fatigue analysis and low cycle fatigue life prediction of cylinder head metal are carried out. The results of the fatigue analysis method are reliable, which can effectively guide the fatigue durability design and optimization of cylinder head. |
