为科学地确定飞机结构的日历寿命，文章认为飞机结构的损伤历程是地面停放环境和空中疲劳载荷协同作用的结果，并提出了以动态的S-N曲线为基础，采用传统的名义应力法和Miner累积损伤理论来估算结构日历寿命的方法。

For determining calendar life of aircraft structure, this paper thought that the damage of the aircraft structure resulted from the synergistic effect of ground parking environment and fatigue load. On the basis of dynamic S-N curve, traditional nominal stress-method and Miner theory, this paper put foreword the method that was applied to the estimation of calendar life of aircraft structure.
