为了研究受电弓滑板和接触导线的摩擦磨损性能,研制了一台高性能滑动电接触磨耗试验机;其可以实现导线和滑板的均匀磨耗,可在一定范围内实现电流、载荷和速度等方面的单、多因素控制,实现对接触导线与滑板摩擦系数、滑板往复移动次数、接触导线与滑板磨耗量等的实时在线测量和数据储存,同时设计了基于LabVIEW的监测界面和数据处理系统.通过实验,分析了强电流对浸铜碳滑板摩擦磨损的影响,得出摩擦系数和磨耗率随电流的增大而增大的结论.

In order to research the pantograph strip and contact wire friction and wear properties, developed a high-performance electro -contact sliding wear testing machine. It can achieve uniform wear between pantograph strip and contact wire. In a certain range , it can realize current, load, speed, single-and multi-factors control , to implement real-time online surveying of contact wire and slide friction oefficient, the number of pantograph contact strips reciprocating mobile , wear volume of contact wire and pantograph contact strips and so on. Simultaneously realizes the data preservation. Based on the LabVIEW designed monitor screen and the data processing system .Through experiments, the strong current effect on the copper impregnation carbon pantograph strips is analyzed, and get a conclusion , coefficient of friction and wear rate increased with the current increased.
