摘要
机车与轨道、受电弓与接触网之间相互作用、相互影响，共同构成铁路大系统。本文通过建立受电弓－接触网动态相互作用模型，并运用机车－轨道耦合动力学理论分析方法，研究了机车－轨道系统对受电弓－接触网系统的振动影响问题。结果表明，列车在几何状态不良的线路上运行时，机车与轨道的耦合振动对弓网系统动态性能影响较大，特别是在较高行车速度状态下，这种影响更为明显，不容忽视。
The whole system of railways consists of the interactive systems of track,train, pantograph and catenary. The dynamic effect of the locomotive track system on the pantograph catenary system is investigated in the paper. A new interactive model of the pantograph and the catenary is developed. The vibrating responses of the roof of locomotive are regarded as the excitations to the pantograph catenary system, which are obtained with the theory of the locomotive track coupling dynamics. Results show that the effect of the locomotive track coupling vibrations is not negligible on the dynamic performance of the pantograph catenary system when the train runs on the track with bad geometric condition, especially in higher speed operation.
