摘　　要：为了研究双S型辐板车轮对钢轨波磨的影响,基于饱和蠕滑力引起轮轨系统摩擦自激振动从而导致钢轨波磨的理论,使用ABAQUS软件,分别建立小半径曲线正双S型辐板车轮和反双S型辐板车轮轮轨系统有限元模型,并用单S型辐板车轮进行模型的验证;采用复特征值分析法,研究双S型辐板弯曲方向、弯曲程度和辐板厚度对钢轨波磨的影响。结果表明:正双S型辐板车轮是一种无波磨车轮,且弯曲程度和辐板厚度对钢轨波磨无明显影响;而反双S型辐板车轮容易引起钢轨波磨,且辐板弯曲程度越大,越容易引起轮轨系统不稳定振动。In order to investigate the influence of double S plate wheel on rail corrugation, based on the theory that the saturated creep force induces the frictional self-excited vibration of the wheelset-track system and then causes rail corrugation, the finite element models of wheelset-track system of positive and negative double S plate wheels with small curve radius were established by ABAQUS software, and the single S plate wheel was used to validate the model.The complex eigenvalue method was used to study the effects of bending direction, bending degree and thickness of double S plate on rail corrugation.The results show that positive double S plate wheel is a non-corrugated wheel, and the bending degree and plate thickness have no obvious influence on rail corrugation.While negative double S plate wheel tends to cause rail corrugation, and the greater of the bending degree, the more likely it is to cause unstable vibration of the wheelset-track system.
