Research on the stamping residual stress of steel wheel disc and its effect on the fatigue life of wheel
Source abstract
Abstract
Abstract The steel wheel is an important safety component of a passenger car, which mainly consists of wheel disc and rim. The steel wheel disc is generally formed by the stamping process, and in this process the great residual stress is generated in the surface which may significantly affects the fatigue life of the wheel. In this paper, a method is proposed to introduce the stamping residual stress of steel wheel disc so as to predict the fatigue life of the wheel accurately. Firstly, the residual stress is obtained from the simulation of stamping process, and the experimental verification is conducted. Then the operating stress is simulated based on the cornering fatigue test. Finally, these two stresses are superposed to predict the fatigue life of the steel wheel. The results show that the predicted fatigue life using this method is closer to the experimental one than the fatigue life without considering the residual stress. The proposed method may provide an accurate and effective tool for predicting the fatigue life of the steel wheel in the cornering fatigue test.
