摘要
通过计算方法来预测机械构件的疲劳寿命是多年来许多学者和工程技术人员追求的目标 ,但迄今为止还没有实际应用的、比较准确的疲劳寿命的纯计算法。文中详细论述了机械构件在窄带随机应力作用下疲劳寿命预测的计算方法。
Fatigue life prediction of machine parts by calculation has been an active area for many years. But so far, no such method applicable in engineering practice is reported. A calculation method used for fatigue life prediction of components under narrow band random loading is discussed in detail.
