Abstract
The present study simulated the actual contact conditions between the catenary and pantograph of a metro line using high-speed ring block current that carried friction and wear testers, from which the uneven wear of the pantograph carbon strip under different working conditions was studied. The results show that the arc power, friction coefficient, and wear amount will change correspondingly with increasing current and normal load. Additionally, all carbon strips showed non-uniform wear after the test, and the edge erosion and wear depth of the carbon strip perpendicular to the moving direction were higher than those in the middle part. The ablation of the back end of the carbon strip running with the catenary was higher than that of the front end.
期刊介绍：
The Journal of Engineering Tribology publishes high-quality, peer-reviewed papers from academia and industry worldwide on the engineering science associated with tribology and its applications.
"I am proud to say that I have been part of the tribology research community for almost 20 years. That community has always seemed to me to be highly active, progressive, and closely knit. The conferences are well attended and are characterised by a warmth and friendliness that transcends national boundaries. I see Part J as being an important part of that community, giving us an outlet to publish and promote our scholarly activities. I very much look forward to my term of office as editor of your Journal. I hope you will continue to submit papers, help out with reviewing, and most importantly to read and talk about the work you will find there." Professor Rob Dwyer-Joyce, Sheffield University, UK
