Abstract: 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.
