车-路垂向耦合系统的动力分析

Dynamic analysis on vehicle-subgrade model of vertical coupled system

针对列车走行的实际情况 ,将轨道 -路基作为参振子结构纳入车辆计算模型 ,建立了车辆 -路基系统的垂向耦合动力分析模型。从系统的观念和体系匹配的角度研究了路基尤其是高速铁路路基设计参数与车辆运行品质的相互关系。

In connection with the train running, the track subgrade being regarded as a part of the vibration structure of vehicle model, a vehicle subgrade model of vertical coupled system has been established. This paper studies the interactions between the vehicle running character and the subgrade (special high speed railway subgrade) design parameters from the system's concept and the viewpoint of the system's mate.
