探讨了按损伤等效原则，将典型服役环境区设计使用环境谱，转换为当量环境谱的编制要求和方法；给出了可供元件与模拟件开展加速疲劳试验选用的当量环境谱，可供新型军用飞机结构开展服役日历年限评定使用。
In this paper, the preparation requirements and methods of using environmental spectrum in the design and processing of environmental service area for environmental degradation were discussed based on the principle of damage equivalence. The equivalent environment spectrum for accelerating fatigue test of components and parts for simulation was given. New military aircraft to carry out the service life of the calendar evaluation use.
