车辆脱轨的耦合动力学分析

Coupling Dynamic Andysis of Vehicle Derailment

本文应用车辆－轨道系统用合动力学理论，对车辆经过一段由缓－圆－缓组成的线路进行了车辆的脱轨稳定性分析。通过对车辆在耦合动力学模型与传统车辆动力学模型下脱轨稳定性之分析比较，指出了进行车辆脱软的耦合动力学分析的必要性。

In this paper the derailment of vehicle is analysed on the basis of vehicle/track coupling dynamics in the condition of negotiating curved tracks consisted of transition,circular curve and transition. Comparing the results obtained by using a coupling dynamics model with that by a traditional medel,it is considered that coupling dynamic analysls is necessary tu carry out vehicle derailment study.
