某轨道车辆车轮疲劳强度分析

Fatigue Strength Assessment of a Railway Vehicle Wheel

采用ABAQUS 2016软件对某轨道车辆车轮进行三维有限元分析,基于EN 13749及UIC 510-5标准计算了车轮在直线、曲线和道岔工况下,不同载荷加载平面下的应力,组合最大主应力投影准则与Crossland多轴疲劳准则对车轮辐板与辐板孔的疲劳强度进行了分析,计算结果说明,这种组合疲劳评定准则的评价结果可以较好的评估车轮抗疲劳性能。

In this dissertation,a rail vehicle wheel is chosen as the research subject.Based on the three-dimensional finite element method we analyze the wheel in Abaqus 2016.Based on three conditions of straight line,curve and turnout in EN 13749 and UIC 510-5 standard,calculate the stress of the wheel under different loading planes.Combined with the maximum principal stress projection criterion and the Crossland multi axle fatigue criterion,the fatigue strength is analyzed for both the wheel web and the web pin hole.The calculation results show that this combined fatigue evaluation criterion can evaluate the wheel fatigue performance very well.
