镁合金车轮动态特性分析及弯曲疲劳寿命预测Dynamic Characteristic Analysis and Prediction of Bending Fatigue Life of Magnesium Alloy Wheels

Abstract: In this paper, bending fatigue simulation analysis was carried out on the magnesium alloy wheels using the software ANSYS workbench of finite element analysis. For the wheels studied, the stress of dangerous points and the corresponding stress values were obtained. Moreover, the fatigue life of the wheel has been predicted based on the nominal stress method, and the results predicted were compared with the results through the analysis of the software. Other dynamic characteristics of wheels were also analyzed, and then compared with the analysis results of aluminum wheels. The results indicate a design development direction for wheels.
