During the course of the life estimation , if the experimental parameters can be carefully chosen , aircraft structure life estimation has a positive effect on the structure fatigue des ign
在寿命估算过程中，只要比较精确地选取各方法所需的经验参数，飞机结构所估算的最终结果对飞机结构抗疲劳设计和型号定寿有很大的指导意义。
We use the stressed fraction that is the most representational and sensitive to corroding to making experiment in combined type equivalent environment spectrum . we can calculate the velocity of corroding , protection period and basal body corroding expansion lifespan , first repair time and the interval of repair period
本文以模拟试验结果和使用中腐蚀损伤数据统计处理为主要依据，并同时满足安全性和经济性两方面的要求，在确定机体使用寿命时，以疲劳定寿结果为主、日历定寿为辅，综合给出飞机机体使用寿命。
