摘要

本文分别建立了简单接触网悬置架空接触导线的有限元模型和受电弓集总质量的非线性模型，并通过接触单元将两者结合起来，从而得到受电弓-接触网动力学系统。基于解析系统的动力学方程，采用Houbolt数值积分法对系统的接触特性进行了分析。针对单受电弓作用下的简单接触网悬挂系统，讨论了不同运行速度下接触网张力、结构高度和跨度长度对受电弓接触网接触力的影响。通过分析，得出了不同速度下受电弓接触丝设计参数对接触特性影响的普遍规律。

Study on influence of contact wire design parameters on contact characteristics of Pantograph-Catenary

Finite element model of overhead contact wire with simple catenary suspension and nonlinear model of pantograph lumped mass were established separately in this paper, these two were bonded through the contact element, and thus Pantograph-Catenary dynamic system was obtained. Based on the dynamic equation of analytic system, Houbolt numerical integration method was adopted to analyze contact characteristics of the system. Aimed at system with simple catenary suspension under single pantograph effect, influence of contact wire tension, structure height and span length on contact force of pantograph-catenary under different running speeds was discussed. Through analysis, the universal law of contact wire design parameters on contact characteristics of pantograph contact wire under different speeds was obtained.
