摘要:

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。

关键词: 腐蚀损伤, 设计使用环境谱, 当量环境谱

Abstract:

According to the damage equivalent principle, design service environment spectrum in typical areas is transformed into drawing up requirements and methods of equivalent environment spectrum; equivalent environment spectra of accelerating fatigue test for components and simulation structures are given. The method can be used to evaluate the service calendar time for fighter aircraft structures.

Key words: corrosion damage, design service environment spectrum, equivalent environment spectrum
