摘　　要：依据美机实用手册介绍的疲劳寿命S-N方程,对超差结构疲劳寿命推导出了一个量化评定方程。并应用该方程对一些典型结构超差形式具体地进行了疲劳寿命量化评定。实践证明,用本文介绍的方法对超差结构疲劳寿命进行定量评定,不仅简捷明快,而且结果可靠。In this article, a quantitative estimate equation is concluded about defected structure’ s fatigue life, which is based on both fatigue life S - N equation described in (America Aircraft Using Handbook) and the authors’ rich experiences deposited during longtime working. Using the equation, fatigue life quantitative estimates of some typical defected structures have been done in the article. Fulfill proves that the method introduced in the article is not only terse and brisk but also reliable.
