| 摘 要： | 介绍了一种采用疲劳有限元分析软件MSC．FATIGUE来对结构件进行疲劳寿命预测的方法。以一阶梯轴为研究对象，在指定的载荷工况下，用有限元法分析了轴上的应力分布情况，并估算危险点处的疲劳寿命。该方法对设计制造过程中机械零部件的疲劳强度分析具有一定的参考价值。

| Abstract: | A new method,which is based on finite element method(FEM) and fatigue life software MSC.FATIGUE,is introduced in this paper to predict fatigue life of structures.A multidiameter shaft is taken as an example,the static elastic stress distribution of the shaft is demonstrated by finite element analysis,and the life of interesting elements or nodes is estimated by MSC.FATIGUE in the specified load case that can cause severe damage.This method can provide a quick and efficient way of fatigue strength analysis o... |
