Study on Wear of Wheel Steel under High Speed Working Condition

Abstract: according to Hertz contact theory, the experimental study and micro-morphology analysis on the fatigue wear of 2 different kinds of wheel materials were conducted by using JD-1 wheel/rail simulation testing machine, to provide a basis for the selection of wheels used on high speed railway. The result shows that the degree of wear of the wheel steel mainly depended on the hardness, the two materials displayed a certain oxidation and stripping and their stripping morphologies were different obviously.
