摘要
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 foundation of fatigue analysis and the evaluation method of fatigue strength are described.With ANSYS software,the finite element model of the bolsters for meter-gauge bogies with the axle load of 21 t is set up,the fatigue strength evaluation of it is made,and with the AAR standard load spectrum,the fatigue life prediction is made for the bolsters.
