摘要
对局部应力 -应变方法估算机械疲劳寿命的计算思路和具体步骤进行了阐述 ,并通过试验和计算实例进一步加以说明 .该方法在解决低周随机载荷下的疲劳寿命预计问题方面具有相当的优势 。
In recent years the local stress-strain method was proved to be a useful method in prediction of machine's fatigue life.In this paper the steps of calculation are described in details,and a real testing example is given.After that we come to the conclusion that we can take the advantage of the local stress-strain method to solve the machine's fatigue life prediction problem.
