Experimental and theoretical investigation of adhesion based on analysis of wheel-rail noise

The efficiency of work for tractive railway rolling stock depends on the values of tractive forces for desired operating conditions. For a more exact prediction of the tractive force it is necessary to take into account the factors that have an influence on processes in wheel-rail contact. The main goal of research, described in this article, is to obtain preliminary results for the furtherdevelopment of a strategy that enables the prediction of adhesion conditions of rail-wheel contact based on noise analysis. This paper includes both experimental and theoretical research. Results from this study are presented and the effectiveness of this work is discussed.
