铁路曲线轨道上轮轨系统相互作用问题随着列车速度的提高显得更加突出,因此对轮轨动力学性能的匹配提出了更高的要求。本文基于车辆—轨道耦合动力学理论,针对提速和高速铁路,开展曲线轨道轮轨动态相互作用性能匹配的研究。主要研究内容如下。(1)基于车辆—轨道耦合动力学理论,提出了曲线轨道轮轨动态相互作用性能匹配的分析方法。 The interaction between the wheel-rail system and the rail curve track becomes more prominent as the train speed increases. Therefore, the matching requirements of the wheel-rail dynamic performance are set higher. In this paper, based on the theory of vehicle-track coupling dynamics, the research on the dynamic performance matching of curved track and wheel orbit for speed-increasing and high-speed railway is carried out. The main research contents are as follows. (1) Based on the theory of vehicle-rail coupling dynamics, an analysis method of dynamic interaction between curved rails and rail is proposed.
