摘要
为确定环境对某型飞机寿命的影响,在分析了该飞机腐蚀疲劳典型部位的结构特点和腐蚀环境的基础上,编制了典型部位的局部环境谱,并根据当量加速原理,通过线性拟合与计算,确定了局部停放环境谱与试验室加速环境之间的折算关系,并应用于该型飞机定延寿工作中,对确定该型飞机寿命起到了重要作用,也为该飞机的使用维护提供了参考。
In order to verify the influence of environment on xx aircraft life, local environment spectrum of typical parts was developed based on the analysis of structural of typical corrosive fatigue components of XX aircraft and corrosive environment. Through the linear fitting and computation, the conversion relationship between the environment spectrum for local parking and the lab acceleration environment was established according to the equivalent acceleration principle, and has been successfully applied to the life extension of xx aircraft. It verified an important effect on aircraft life and supplied a reference on aircraft operation maintenance.
