摘要
目前中国地铁动态检测行业发展迅速,接触网动态检测作为检测弓网关系状态的重要项目,多采用对接触网检测参数进行阈值管理的方式,用以发现局部接触网参数异常、弓网关系优劣的状况并复查整改消除隐患。为填补地铁行业内刚性接触网综合评价的空白,克服传统方法对接触网整体质量量化的不足,采用标准差的计算方法对接触网静态参数进行计算,运用Topsis的评价方法对弓网运行动态参数进行计算,从而充分发挥每个接触网动静态检测数据的作用,从静态、动态两方面对刚性接触网质量状况进行综合评价。根据郑州地铁日常运营检测数据,参考轨道质量指数TQI评价体系,建立刚性接触网质量指数CQI评价体系,对刚性接触网质量状况进行区段性的评价,对基础设备设施管理、合理分配检修维护资源、实现状态修具有指导意义。
Dynamic metro detection industry is developing rapidly in our country.As an important item to detect the state of the pantograph-catenary relationship,threshold management is often adopted in dynamic catenary detection to identify the abnormal parameters of the local catenary and the status of the pantograph-catenary relationship,and to check,rectify,and eliminate hidden dangers.In order to comprehensively evaluate the rigid catenary in the metro industry and overcome the deficiencies of traditional methods in quantifying the overall quality of the catenary,the static parameters of the catenary are calculated using the standard deviation,and the dynamic parameters of the pantograph and catenary are calculated by the Topsis evaluation method.This method gives full play to the role of the dynamic and static detection data of each catenaryand the quality of the rigid catenary is evaluated in an all-round way.According to the daily operation test data of Zhengzhou Metro and referring to the TQI evaluation system of the track quality index,a CQI(Rigid Catenary Quality Index)evaluation system of the rigid catenary quality index is established to evaluate the quality status of the rigid catenary in sections.This study has significance for the management of infrastructure facilities and the rational allocation of maintenance resources to achieve condition-based maintenance.
