摘要

本研究采用高速环块电流承载摩擦磨损试验机，模拟地铁线路接触网与受电弓的实际接触情况，研究受电弓碳带在不同工况下的不均匀磨损。结果表明，电弧功率、摩擦系数和磨损量随电流和正常负载的增大而发生相应的变化。此外，试验后所有碳带均表现出不均匀磨损，且垂直于运动方向的碳带边缘侵蚀和磨损深度均高于中间部分。随接触网运行的碳带后端烧蚀率高于前端烧蚀率。

Experimental research on the non-uniform wear of the carbon strip of the metro pantograph

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."
