Residual Stress of Wheel Tread for Freight Car
초록
Recently, several wheel 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 the present paper, the residual stress of wheel using x-ray diffraction system is investigated. the result shows that the residual stress of wheel is depend on the running distance and wear rate of wheel.
