摘要
阐述了多种车辆与轨道垂向耦合振动简化模型的求解原理，提出一种采用Ｔｉｍｏｓｈｅｎｋｏ梁的简化模型和仿真方法，并给出运用这类模型模拟现场试验的结果。模型可为研究高速重载条件下的机车车辆转向架和轨道零部件的中低频响应以及结构参数优化提供某种途径。
Thls paper describes several simplified models of track related to the vertical coupling vibration with railway vehicles,The theoretically analytlcal methods for tbe track models are also shown,In order to compare with the experimental data,such as rail dynamic strain from field test,anw simple model of vehicle/track using Timoshenko Beam Elenlent with elastic foundation and a computer dynamic simulation method are developed,The model can be used to predict dynamic wheel/rail loads below 100 Hz and to investigate the responses of components in trucks and track,It can also be used to optimize the parameters of suspension of vehicles and track.
