摘要

The tribological performance of metro rigid overhead lines against pantograph sliders was experimentally studied. The test parameters from actual metro lines were adopted. During testing, the friction force, wear volume, temperature, vibration of the pantograph slider, voltage drop, and current correlating with arc ablation were collected. The worn topography of the slider and wire was observed. Experimental results illustrate that the direct current (DC) and vibration of the slider can largely affect the tribological performance of the rigid overhead line against the pantograph slider. Main wear mechanisms are the arc ablation, plowing wear and adhesive wear. The abnormal joint between two slider blocks can bring about severe plowing wear of the overhead line.
