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 determine the influence of environment on the life of a certain aircraft, a local environment spectrum of a typical part was compiled based on the analysis of the structural characteristics and corrosion environment of the typical parts of the aircraft. Based on the principle of equivalent acceleration, Calculated and determined the relationship between the partial parking environment spectrum and the accelerated environment of the laboratory, and applied it to the definite life extension work of the aircraft, played an important role in determining the life of the aircraft and also provided the use and maintenance of the aircraft reference.
