Abstract The wear occurring in the wheel-rail contact has a strong impact on the entire railway system consisting of the rolling stock and the infrastructure; essentially, the wear depends on the location of the contact area on the running surfaces and on the stresses acting in the contact area. Some combinations of wheel and rail profiles are known to be very sensitive even to small changes of the relative kinematics of wheel and rail which can be caused not only by displacements of the wheelset relative to the track, but also by structural deformations of wheelsets and rails. The paper presents a refined vehicle-track model in which flexible bodies representing the wheelsets and the rails are combined with a rather detailed wheel-rail contact model. It shows the modelling approaches, in particular the integration of the wheel-rail contact into the entire model, and explores the impact of structural deformations on the wheel-rail contact.

模拟轮对和轨道的结构柔性对轮轨接触和磨损的影响

摘要 轮轨接触处的磨损对包括机车车辆和基础设施在内的整个铁路系统产生强烈影响；基本上，磨损取决于运行表面上接触区域的位置以及作用在接触区域中的应力。众所周知，一些车轮和轨道轮廓的组合即使对车轮和轨道相对运动学的微小变化也非常敏感，这种变化不仅可以由轮对相对于轨道的位移引起，还可以由轮对和轨道的结构变形引起. 该论文提出了一个改进的车辆轨道模型，其中代表轮对和轨道的柔性体与相当详细的轮轨接触模型相结合。它显示了建模方法，
