摘要
针对国内城市轨道交通近年来频繁出现的弓网系统异常磨耗现象,从接触副结构特征、故障现象及其时空属性、处理措施等方面梳理了近10条地铁线路弓网接触副异常磨耗事件。分析当前国内外关于法向载荷、电流、电弧等因素影响弓网系统磨耗的主要研究成果;论述弓网系统磨损机制的研究进展;介绍国外研究团队关于弓网系统磨损模型的研究历程。基于工程和科研现状分析结果,参考弓网系统磨损模型制定了弓网系统异常磨耗现象的根因分析方法;从地面试验、线路试验和仿真分析、数据处理技术等角度梳理异常磨耗致因的验证和确认手段,并介绍刚性接触网关节和跨内数据分割处理方法,同时针对异常磨耗的关注热点,利用仿真分析技术实现了滑板凹槽磨耗和接触线拉出值布置影响系统性能的量化评估;结合弓网系统相关标准的梳理,介绍抑制异常磨耗相关的运用维保措施。最终提出包括异常磨耗定义和评估、根因分析、验证与确认、维保控制四个阶段的弓网接触副异常磨耗问题应对方案。并基于调研分析结果和异常磨耗问题防治框架,展望了科学和工程问题的潜在探索空间。研究结果可为城市轨道交通相关单位应对弓网系统异常磨耗事件提供技术和管理参考。
Aiming at the frequent abnormal wear phenomenon of pantograph-catenary systems in domestic urban rail transit in recent years,the anomaly of pantograph-catenary contact behaviour from nearly 10 subway lines are sorted out from the perspectives of structural characteristics,temporal and spatial attributes of fault phenomena,and treatment measures.The main research results regarding the influence of contact force,current,arc,and other factors on the wear of pantograph and catenary system are analysed;The researches on the wear mechanism of pantograph and catenary system are discussed;A wear model of the pantograph-catenary system proposed by foreign research teams is introduced.Based on the current status analysis of engineering and scientific research,the root cause analysis method of the abnormal wear of pantograph and catenary system is formulated from the wear model;From the perspectives of the ground test,line test,and simulation analysis,data processing technology,etc.,the methods available for verifying and validating the cause of abnormal wear are sorted out,together with introducing the method of segmenting operating data between rigid conductor overlaps and sections.Aiming at the hot topics of abnormal wear,the quantitative evaluation of system performance affected by wear groove on pantograph strip and rigid conductor stagger arrangement is realized by using simulation technology.Referring to the standards analysis of pantograph and catenary system,the application and maintenance measures to inhibit abnormal wear are introduced.Finally,a framework dealing with the abnormal wear of pantograph-catenary contact pairs is proposed,which includes four stages:abnormal wear definition and evaluation,root cause analysis,causes verification and validation,and maintaining control.Based on the status analysis results and the proposed framework,the future exploration content of scientific and engineering problems has been prospected.The results of the study would provide technical and management references for the re
