摘要

基于有限元Arbitrary Lagrangian Eulerian(ALE)方法和Archard磨损理论建立了CRH5型动车组车轮的磨损分析模型。通过静态以及稳态分析结合修型运算,获取了车轮在典型工况下的磨损规律,包括车轮踏面磨损程度和磨损量沿踏面分布的动态变化规律。基于以上工作,又对不同磨损程度的车轮进行了疲劳寿命分析,总结了在磨损过程中,车轮的疲劳损伤速率随磨损的动态规律。结果发现:车轮的疲劳损伤速率在初期时呈显著下降趋势,当磨损超过整个仿真磨损量的70%时趋于平稳。

Abstract

Apply Arbitrary Lagrangian Eulerian（ ALE） and Archard wear theory to establish wheel wear analysis model of CRH5,by finite element static and steady state analysis,combined with repair operations to obtain the wheel wear law under typical conditions,including dynamic distribution regularity along the surface of the wheel tread wear degree and wear volume.Fatigue life of the worn wheel was also studied based on steady state analysis to get the evolutional law of the fatigue damage rate of wheel changing with the amount of wear. The results show that the fatigue damage rate of the wheel is significantly decline initially however being steady when it’s over 70% of the whole simulation wear loss.
