Contact point lateral speed effects on contact strip wear in pantograph – catenary interaction for railway operations under 15 kV 16.67 Hz AC systems

The design of a railway catenary is subject to multiple decisions regarding the geometry system. In particular, horizontal contact wire determines evolution wear and strip over time. obtained through stagger, lateral displacement at supports. value length span, curvature track, train speed within span determine which point between pantograph moves from side side. A wider stagger corresponds larger area distribution strip. However, also important due sliding contact. Thus, affects point. this paper, study effects on presented. findings include model effect recommendation for lower limit 330 mm/s. • Wear models are needed overcome uncertainties lack field measurements. Dependence speed, force current has been studied extensively. known influence wear. dependence studied. updated consider new findings.
