摘　　要：接触轨系统是城市轨道交通常用的接触网方案,其最大挠度对靴轨系统受流质量影响较大。本文基于接触轨跨距情况、列车时速、靴轨作用力等不同条件分别对接触轨挠度进行分析研究,从而得出接触轨系统动、静挠度情况,为接触轨系统设计选型提供参考。Conductor rail system scheme is a common OHL scheme for urban rail transit. Its system deflection has a great influence on the current collection quality of collector shoe-rail system. The paper analyzes and studies the deflection of the conductor rail when it is under different conductor rail spans, train speeds and collector shoe-rail acting forces, obtains the status of dynamic and static deflections of conductor rail system, providing references for design and selection of conductor rail system.
