Research on the dynamic evolution of competitive and water-film-mediated wear mechanisms of the carbon strips in the pantograph-catenary system at low temperature

Abstract To investigate the evolution of wear mechanisms in carbon strips at low temperature, this study conducted comparative friction tests on copper-impregnated carbon strips at room temperature (25 °C) and low temperature (-20 °C). To replicate operating conditions, the exper...
