摘要: 

以紫铜/铬青铜摩擦副为研究对象模拟受电弓与导线的服役条件,在HST100型销盘式高速载流试验机上考察了该材料在动载荷(按正弦规律加载)条件下受流摩擦磨损性能。结果表明:在动载荷条件下,电流是影响其摩擦磨损性能的重要因素。摩擦系数、磨损率均随电流的增大递增,但随着电流的进一步增加其增大趋势减缓;粘着磨损、电弧侵蚀、塑性变形是其主要的磨损形式。

Abstract

The tribological characteristics of T2/QCr0.5 rubbing pairs under the load of sine shock pulse and in the electrical current of various intensities, which simulated working conditions of the pantograph-wire system used in electrical railway, were examined on the pin-on-disc friction and wear tester of HST100.The results show that the electrical current is the important effect factor on tribological properties with electrical current, friction coefficient and wear rate increase with current intensity whereas the tendency is slow up with the further increasing of electrical current. The most wear form is adhesive wear, arc erosion and plastic deformation.

Key wordsdynamic load    current-carrying    tribological characteristics    friction coefficient    wear rate    adhesive wear    arc erosion    plastic deformation
