摘要
在分析负重轮破坏机理的基础上 ,用断裂力学疲劳破坏的数学模型和疲劳寿命预估方法 ,对负重轮进行了疲劳寿命预估 ,并对结果进行了实验验证。验证表明 ,断裂力学的疲劳寿命预估方法用于负重轮的疲劳破坏有一定实用价值和理论参考价值。
On the basis of an analysis on the mechanism of breakage of road wheel, with the fatigue failure mathematical model and the fatigue life prediction method from fracture mechanics, road wheel's fatigue life is predicted The results of prediction are then verified with those from actual tests It is shown that the application of fracture mechanics and fatigue theory in the prediction of road wheel's fatigue life is practical and reliable
