Abstract

The aim of this paper is to estimate the damage of railway carriage wheels\ncaused by lock-up braking. First, we investigate the typical characteristics of\nwheel-rail contact including the parameters of contact patch, longitudinal\ncreep and coefficient of adhesion. Then we show the current requirements\nconcerning the wheel-slide protection systems and determine the points which\nshould be reviewed. To predict the effect of the sliding phenomenon, material\nproperties are needed, as well. Afterwards, a simplified thermal simulation is\nbuilt to estimate where martensite formation may occur.\n
