采用欧拉-伯努利梁结构的接触网和受电弓的二质量块模型建立了弓网垂直耦合动力学模型，通过拉格朗日方程推导出弓网系统运动微分方程组，并利用Newmark法编写数值仿真程序，在给定的条件下，讨论不同速度下弓网耦合系统的动态性能。采用MATLAB对高速受电弓与接触网的相互作用进行仿真并对结果进行分析，为研究不同速度下受电弓与接触网参数的优化奠定基础。

This paper uses the Euler-Bernoulli beam structure of catenary and two mass model of pantograph, es-tablishes the vertical coupling dynamics model of the pantograph catenary system, and derives pantograph-catena-ry system’s motion differential equations through the Lagrange equation. Using Newmark method, this paper also writes the simulation program, and in given conditions, discusses the dynamic properties of pantograph-catenary coupling system under different speeds. Using MATLAB, this paper simulates the interaction of high-speed panto-graph and catenary, analyzes the simulation results, and lays the foundation for pantograph and catenary's further parameters optimization under different high speeds.
