Abstract

In this paper, slip wear phenomenon of train was studied by traction force of acceleration and braking force of deceleration. First, the slip wear phenomenon on train operation mode was analyzed when powering, coasting and braking each and then rail wear was analyzed from the slip wear data. Especially, the data proved correlation between slip wear and deceleration rather than acceleration. Second, If velocity of a train is constant, even though the velocity is high, ATO logging data and measurement data proved that the rail wear is not serious. It will help for efficient braking force operation providing fundamental data to braking step control.
