Damage Evaluation of Wheel Surface for Railway Vehicle Based on Contact Positions

초록

The defect and the result of the crack propagation may cause the damage of the railway vehicle or even derailment. Therefore, it is important to evaluate the damage patterns of the wheel tread based on contact positions between wheel and rail. In the present paper, characteristics of wheel tread based on contact positions, running distance and brake pattern are evaluated. The result shows that the damaged of wheel tread is remarkably depended on the contact positions between wheel and rail
