Abstract

Research purposes: With the increase of the operating mileage of electrified railway, the operation and maintenance pressure of catenary is increasing day by day. In order to ensure the continuous, safe and stable operation of the catenary system, it is urgent to develop an objective and accurate quality evaluation method that can reflect the dynamic and static parameters of the catenary, equipment quality, and mean time between failure. Research Conclusions: (1) In this paper, an evaluation method of catenary quality based on weighted rank sum ratio (WRSR) algorithm is proposed. This method adopts the non-integer rank evaluation method, which can bring the numerical difference between the corresponding evaluation indicators of the evaluation object into the entire evaluation algorithm to obtain more objective evaluation results. At the same time, the method adopts the two-level evaluation index of dynamic and static indicators, equipment quality indicators and mean time between failure and the WRSR method, which has strong operability, easier expert intervention and scientific and reliable results. From the theoretical analysis and experimental data, it can be seen that this method can scientifically and effectively evaluate the quality of rail transit catenary equipment in a certain period of time, and the analysis results have a high reference value for the scientific operation and maintenance of the catenary and the formulation of operation and maintenance strategies. (2) The research results are applicable to the professional field railway catenary.
