Health Assessment Method for Urban Rail Transit Pantograph-Catenary System Based on Condition Monitoring
摘要
Abstract
In order to improve the safety and reliability of urban rail transit operation,a comprehensive health assessment system was constructed based on condition monitoring technology.Firstly,the mecha-nism of the pantograph-catenary system was elaborated in detail,the health assessment was intro-duced,and the characteristics of pantograph-catenary health were analyzed.Secondly,the key factors affecting the operation status of pantograph-catenary system were identified,and a pantograph-catena-ry health evaluation index system was established from two dimensions:monitoring parameter indica-tors and appearance status indicators.Then,the weights of each indicator were determined through the Analytic Hierarchy Process,and a 4-level health evaluation standard was constructed.Finally,to verify the effectiveness of the evaluation system,a case study was conducted on an urban rail transit line that had been in operation for over 5 years in Shenyang.The results showed that the health scores of each section ranged from 80.1 to 95.5,with a failure rate of 0.008%to 0.031%;the higher the health score,the lower the failure rate,and there was a clear negative correlation between the two.The research re-sults confirm the usability and effectiveness of the pantograph-catenary health evaluation index system in monitoring multidimensional data and reflecting potential risks of the system.The proposed evalua-tion method can comprehensively and accurately reveal the operating status of pantograph-catenary system,providing reliable basis for pantograph-catenary maintenance decisions.关键词
