The steepness of the rising branch of adhesive characteristics between wheel and rail

Abstract

The article describes the limiting parameters of the rising branch of adhesive characteristics. Attention is paid to the actual results of experimental research conducted by the authors. A summary of the obtained knowledge is made. In addition, a test stand of tram wheels driven by the synchronous motor and the carried out experiments are described. A comparison of the achieved results is drawn.
