| 中文摘要: |
| 对铁路工程领域普遍存在的轮冲击振动现象进行了理论与试验研究。将车辆模拟为移动的多刚体振动系统，将轨道描述成离散点支承连续梁结构，应用快速数值 发方法编制了ＶＩＣＴ模拟软件，实现了轮轨冲击振动的快速数值模拟。 |
| 英文摘要: |
| This paper deals with the theoretical simulation and experimental measurement on the wheel/rail impact vibrations that widely occur in railway engineering. A vehicle/track interaction model is built, according to the theory of vehicle track coupling dynamics. The vehicle is modeled as a multibody dynamic system and the track is described as a discretely supported beam structure. A computer program, VICT, is designed to simulate numerical responses of the wheel/rail systems due to impact excitations. A full scale field experiment is performed on the wheel/rail impact vibrations at a rail joint. Good correlation is obtained between the experiment data and the simulation results. |
