Abstract
Recently, several wheels for freight car in running had experienced the wheel failure due to fatigue crack, overheat braking and other factors. Severe heating of the wheel during tread braking was believed to be a contributing factor of derailment. It is necessary to evaluate the residual stress in wheel tread in order to manage the safety of wheel. In the present paper, the residual stress of wheel regarding to running distance using x-ray diffraction system is investigated. The result shows that the residual stress of wheel is depend on the running distance, wear rate of wheel and thermal gradient during brake application.
