摘要:
[目的] 为保障城市轨道交通刚性接触网安全运行,需建立刚性接触网健康状态综合评价方法。[方法] 基于层次分析法,构建动态弓网关系指标、静态接触网性能指标、运营需求与运行状态的两级综合评价指标体系;采用功效系数法和统计标准化法,对检测指标进行量纲一化处理,并结合数据驱动建立判断矩阵,开展权重设计;采用相对标准化法对设备运行状态、运营需求进行分级评价,结合判断矩阵加权平均法和最大隶属度法开展评价。[结果及结论] 所提方法可全面评价刚性接触网系统多维度健康状态,精准反映其真实服役现状,有效识别接触网参数缺陷和存在问题,进而为城市轨道交通刚性接触网系统全流程闭环运维提供技术支撑。
Abstracts:
[Objective] To ensure the safe operation of urban rail transit rigid catenary systems, a comprehensive evaluation method for assessing their health status is proposed. [Method] A two-level comprehensive evaluation index system is established based on AHP (analytic hierarchy process), incorporating dynamic pantograph-catenary relation indicators, static catenary performance indicators, operational demands, and system operating status. The efficiency coefficient method and statistical standardization method are used to normalize the dimensions of the evaluation indicators, and a judgement matrix for weight assignment is constructed based on data-driven approach. A relative standardization method is applied to classify equipment operating conditions and operational demands. An evaluation is conducted using a combination of weighted average based on the judgement matrix and the maximum membership degree method. [Result Conclusion] The proposed method enables a comprehensive assessment of the multi-dimensional health status of rigid catenary systems, accurately reflecting their actual service condition and effectively identifying parameter defects and existing issues, thus providing technical support for the full-process closed-loop operation and maintenance of rigid catenary systems in urban rail transit.
