Research of Influence of Pantograph-Catenary System Vibration on Irregular Wear of Carbon Contact Strip

In order to study the effect of carbon contact strip vibration on the irregular wear, a simplified pantograph-catenary coupled model is established to analyze its vibration response. It is found that the vibration of pantograph and rigid catenary mainly occur at low frequency and has little effect on irregular wear, whereas irregular wear of the carbon contact strip is from its the third vertical bending mode to its third lateral bending mode, which aggravate the mechanical wear in the middle of the carbon contact strip and the mechanical-electrical wear on both sides.
