中文摘要：

首先介绍了受电弓和接触网的动态系统有限元模型的建模过程,利用建立的接触网有限元模型,对其进行模态分析得到了接触网的固有频率和模态,并讨论了跨距为65m时的频率变化情况;最后讨论了不同速度时接触网动态压力的变化情况,并与实测兰武线在速度V=80km/h进行对比,并对结果上的差距原因进行分析,说明了利用ANSYS进行仿真的可行性.

英文摘要：

This paper firstly introduces the finite element model of dynamic system of pantograph and catenary modeling process, and uses the established finite element model of the catenary.The modal analysis catenary of natural frequency and modal are obtained,then discussed frequency changes when the span is 65m.This paper discusses the different speed of catenary dynamic pressure changes.In line with the measured LanWu speed V=80 km/h,and the gap on the reason analysis to the result.It Illustrates the feasibility of using ANSYS simulation.
