Effects of Arc Discharge on Friction and Wear Properties of Metal-impregnated Carbon Strip Sliding against Cu Trolley under Electric Current
电弧能量对浸金属碳滑板材料载流摩擦磨损性能的影响

Influence of arc discharge on the contact strip on the pantograph of electric railway vehicles was studied.The experiments were carried out on an HST-100 tribo-tester with metal-impregnated carbon strip under electric current,which simulated working conditions of the pantograph-wire system used in electric railway.Statistical correlation coefficient was applied to describe quantitatively the correlation between friction coefficient and arc discharge,and experiment data were processed through non-linear regr...
