Study on choosinglocomotive wheel - rail rolling contact theory for the wheel wear simulation

Abstract

In the analysis of vehicle wheel wear, the extent of wheel wear is
directly dependent on the contact spot area, normal force, creepage force
and creepage rate etc. Different wheel and rail rolling contact theory will
give different results of the aforementioned parameters, thus the
accuracy of wheel abrasion simulation results also varies. This paper
presents the research results of calculated parameters in the contact spot
of wheel and rail. The precision of different contact theories is compared
and analyzed, which provides a basis for the selection of wheel and rail
rolling contact theory in wheel wear simulation.
