摘要

研究目的:研究建立无砟轨道结构动力学性能评估的方法和手段。
研究方法:应用车辆一轨道藕合动力学理论，建立列车-无砟轨道空间耦振动模型，从而导出弹性地基 上轨道板的运动方程;应用开发的无昨轨道动力学仿真软件THACKDYNA，系统地研究评估遂渝线综合试验 段无作轨道及其过渡段的动力学性能。
研究结果:快速客车、重载货车以及普通货车通过路基上板式轨道时，轮轨垂向力、轮轨横向力、脱轨系 数、轮重减载率,CA砂浆动应力、路基面动应力等动力学指标均小于容许值。
研究结论:遂渝线无砟轨道结构动力学性能满足设计姿求，过渡段结构设计方案是合理的;对于双块式轨 道过渡段，适当降低2种轨道连接点处双块式轨道前几个扣结点的软下胶垫刚度，可改善过渡段的动力学 性能。

Abstract

Research purposes: The purposes are to establish the methods and means of making evaluation of the dynamic performance of ballastless track.
Research methods: Based on the coupling dynamics theory o# vehicle and track, the spatial dynamic model of train and ballastless track and the movement equations of slab laid on the elastic base had been set up. With the developed dynamic simulation software TRACKDYNA, the dynamic performances of the ballastless track in Suining-Chongqing Railway had been studied systematically.
Research results: When the high-speed passenger train，heavy-haul freight train and ordinary train pass, the wheel/ rail vertical force, wheel/rail horizontal force，derailment coefficient, reduction rate of wheel load，dynamic stresses of CA mortar, dynamic stresses of subgrade surface etc. are less than their allowances.
Research conclusions: The dynamics performance of the ballastless track of Suining-Chongqing Railway can meet the design requirement and the structure of track in transition area is rational. For the transition area of double slab ballast track，to reduce the stiffness of rubber cushion under rail of fastening joint at two kinds of track joints in front of double slab can improve the dynamic performance in transition area.
