摘要

随着重载列车的不断发展,辐板的热-机疲劳成为车轮破坏的主要形式。基于Ansys有限元软件,对车轮辐板的制动热应力进行分析,利用单轴疲劳准则和Haigh-Goodman疲劳极限图对车轮辐板进行疲劳评估。分析了制动热应力对车轮辐板单轴疲劳的影响。结果发现:(1)未考虑制动热应力下,新制轮和磨耗轮辐板的各节点的抗疲劳性能均满足要求;制造态残余应力使辐板的疲劳薄弱位置发生了转移;最易发生疲劳的截面为0°、180°和40°～60°。(2)考虑制动热应力下,新制轮和磨耗轮辐板的各节点的抗疲劳性能均满足要求,但是在FPH和BPR处平均应力未能达到安全要求。

Abstract

With development of heavy load train,the thermomechanical fatigue is the main failure form of wheel plate. The thermal stress was analysisbased on ANSYS softwarein this thesis. Uniaxial fatigue criterion and fatigue limit diagram of HaighGoodman was used to evaluate wheel plate fatigue. The effect of thermal stress on uniaxial fatigue of wheel plate was analysis. The result show that（ 1） Without consider brake thermal stresses,the fatigue resistance of each node of the new and worn wheel are satisfactory,and the manufactured stresses cause the fatigue weak position to transfer. The sections most prone to fatigue are located in 0 °、180 °and 40° ～ 60 °.（ 2） Considering brake thermal stresses,the fatigue resistance of each node of the new and worn wheel are satisfactory. Nevertheless,the mean stress of FPH and BPR not meet safety requirements.
