Development of the theory and methodology of controlling the local tribological contact thermomechanical loading

Abstract

Theoretical and experimental studies have been carried out, which confirmed the fact that the contact temperature is the most important factor affecting the entire complex of service properties of the contacting materials. The authors of the paper propose the control of the frictional interaction of the tribological contact by controlling the temperature by forced cooling, which will stabilize the coefficient of engagement of the wheel with the rail.
