摘　　要：对轨道交通行业转向架构件的两种疲劳校核计算方法及步骤进行了介绍,提出一般疲劳极限线图校核步骤存在的影响因数。对有限元分析的载荷谱、后处理采用的疲劳评估失效准则、疲劳极限线图选取等进行分析,探讨了各因数的正确使用条件,最后通过一个实例演示了整个计算方法。In this paper,firstly,two processes of bogie designing against fatigue in rail industry is introduced,and several relevant factors such as load spectra for finite element analysis,fatigue failure criterion for post- processing,and the determinations of fatigue limit graph are mentioned. Writer states a overlooking of these uncertain factors may lead to a mistake,and unveils the way for correctly choosing options from these uncertain factors. A fatigue verifying instance is shown in the end.
