摘要
随着轨道交通线路运营速度的不断提高,对弓网系统动态性能的要求越来越高。跨距是刚性接触网的一项关键参数,弓网之间的良好受流质量需要选取合理的跨距,因此有必要对不同速度等级下刚性接触网跨距的选取进行研究。本文通过建立刚性接触网模型与受电弓模型,分析不同型号受电弓以不同速度通过不同跨距刚性接触网的弓网动态性能参数,得出不同速度等级下与不同型号受电弓相适应的刚性接触网跨距,为受电弓及刚性接触网系统设计提供研究基础。
Along with the constant increase of servicing speed of urban rail transit lines,the requirements for the dynamic performance of the pantograph-catenary system are getting higher and higher.Reasonable selection of the span,which is a key parameter of rigid catenary,is able to ensure fine current collection between pantograph and catenary.Therefore,it is necessary to study the selection of rigid catenary spans under different speed levels.In this paper,by establishing rigid catenary model and pantograph model,and through analyzing the dynamic performance parameters of the rigid pantograph-catenary system when different types of pantographs passing through different spans at different speed levels,the rigid catenary spans,which are able to match different types of pantographs at different speed levels,are obtained,and these will be able to provide the basis of research for design of rigid catenary system.
