摘要
锚段关节是高速铁路接触网系统的重要组成部分，其动态行为直接影响高速运行工况下的弓网受流性能。目前，吊弦断裂等吊弦故障频繁出现在高速铁路接触网锚段区域，并对高速铁路弓网系统的运行稳定性产生了显著威胁。研究吊弦故障影响下的接触网锚段关节区域的动态行为对确保弓网系统受流性能有着重要意义。文章以某高速铁路接触网系统的锚段区域为研究对象，采用有限元方法建立了完整的三维锚段关节模型，并进一步搭建了包含锚段关节区间的“受电弓-接触网”耦合模型；基于该模型仿真分析了不同运行速度对弓网耦合接触力的影响，并进一步研究了锚段关节处吊弦故障影响下的锚段区域动态行为。由仿真计算结果可见，建立的锚段关节模型能够准确描述其动态行为，锚段关节处吊弦故障会显著恶化弓网受流性能和邻近区域的吊弦动力学行为，增加吊弦断裂风险，因此有必要在接触网巡检时对锚段关节处的吊弦状态进行仔细检查。
Abstract
Overlaps serve vital components of the overhead contact system (OCS) on high-speed railways
and their dynamic behaviors directly affect the current-collecting performance of the pantograph-catenary systems in the high-speed operational conditions of trains. Instances of dropper breakage and other failures have been prevalent in overlap sections along high-speed railways
directly threatening the operational stability of the pantograph-catenary systems. Studying the dynamic behaviors of overlap sections under the influence of dropper failures holds important significance in guaranteeing the current-collecting performance of the pantograph-catenary systems. This study focused on the overlap sections within the catenary system of a high-speed railway. Based on a three-dimensional overlap model created using the finite element method
a pantograph-catenary coupling model incorporating the overlap sections was established. This model was utilized to analyze the influence of various operating speeds on the pantograph-catenary coupling contact force
and to delve into the dynamic behaviors of the overlap sections under the influence of dropper failures. The results from simulation calculations indicate the efficacy of the established model in accurately representing the dynamic behaviors. Dropper failures at the overlaps significantly degrade the current-collecting performance and the dynamic behaviors of neighboring droppers
elevating the risk of dropper breakage. Therefore
assessing the condition of droppers at overlaps is necessitated during the OCS patrol inspections.
