阐述有限元分析疲劳分析流程,试验数据作为有限元分析输入的边界条件,通过利用模态叠加进行瞬态响应分析,振动疲劳分析,对两种设计方案进行定性分析,为设计提供理论参考。
The finite element analysis fatigue analysis process is presented. The experimental data are used as the boundary conditions for the finite element analysis. The transient response analysis and the vibration fatigue analysis are carried out by modal superposition, and the qualitative analysis of the two design schemes is provided, providing a theoretical reference for the design.
