介绍了疲劳分析的理论基础和疲劳强度评定方法,利用ANSYS软件,建立了21t轴重米轨转向架摇枕的有限元模型,对其进行了疲劳强度评定,并用AAR标准载荷谱,对摇枕进行疲劳寿命预测。
The theoretical basis of fatigue analysis and fatigue strength assessment method are introduced. The finite element model of bolster for 21t axle weight bogie bogie is established by using ANSYS software. The fatigue strength of the bolster is evaluated with AAR standard load spectrum. Fatigue life prediction.
