Dynamic analysis using finite elements to calculate the critical wear section of the contact wire in suburban railway overhead conductor rails [PDF]
, 2008 The purpose of this study is to determine the critical wear levels of the contact wire of the catenary on metropolitan lines. The study has focussed on the zones of contact wire where localised wear is produced, normally associated with the appearance of

Analysis of Dropper Stress in a Catenary System for a High‐Speed Railway
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 When the pantograph slides over the contact wire at a high speed, there are cyclic stresses acting on droppers. The cyclic stresses are related with the fatigue life and fracture of the dropper. Thus, the stress calculation of the dropper is particularly important to ensure the safe operation of a train. In this paper, a simple model based on a span of

Pantograph Catenary Performance Detection of Energy High‐Speed Train Based on Machine Vision
Mathematical Problems in Engineering, Volume 2022, Issue 1, 2022., 2022 With the rapid development of high‐speed rail in China, addressing the issue of safety assurance during the operation of the train is very important. A very important part of a train’s power supply system is the pantograph and catenary system, which consists of a pantograph and a catenary. Failure of the pantograph‐catenary system can cause significant
