| 摘要： | Due to the development of Rail Transit,the problem of characteristics of wheel/rail rolling contact is researched by domestic and foreign scholars.This article first introduces the theory of wheel/rail rolling contact based on the Hertz theory.Then through the combination of UM multi-body dynamics simulation software with the finite element software ABAQUS,characteristics of wheel/rail rolling contact are analyzed contrastingly from different wheel on the transverse quantity and different friction coefficient.Wheel/rail damage to overloaded railway mainly includes the wheel/rail contact fatigue and wear,the driving stability is also directly influenced by wheel/rail wear on high speed railway,and the research on rolling contact fatigue of wheel/rail and wheel/rail wear problems is based on data such as elastic-plastic stress and strain appear in the course of wheel/rail rolling contact,so the research on the characteristic of wheel/rail rolling contact has a certain significance.The results show that: the results obtained by finite element method based on the theory of elastic-plastic is more visualized and closer to real.;The transverse quantity mainly affects the normal characteristics of wheel-rail rolling contact;The maximum Mises stress and maximum normal contact stress appear in the working condition without transverse quantity;Attack Angle and friction coefficient mainly affects the tangential characteristics. |
