摘要

随着科学技术的发展,飞机的应用越来越广泛,腐蚀性污染对飞机的运行造成了很大的障碍。本文提出了一种拟正态分布模型来计算腐蚀污染环境和飞机结构损伤,并进行了静张力、常规环境腐蚀和加速腐蚀三组实验。由于正态分布是一种自然分布,不受人类活动的影响,而大气环境是一种更符合正态分布的自然环境,因此本文提出了一种用于腐蚀预测计算的暂定正态分布模型。本文可以预测飞机结构在腐蚀和污染环境下的疲劳寿命,准确率达到95%以上。

Fatigue life of aircraft structure in corrosion and pollution environment
With the development of science and technology, the application of aircraft is more and more extensive, and corrosive pollution has caused great obstacles to the operation of aircraft. In this paper, a quasi-normal distribution model is proposed to calculate the corrosion pollution environment and aircraft structure damage, and three sets of experiments are carried out for static tension, conventional environment corrosion and accelerated corrosion. Because the normal distribution is a natural distribution and is not affected by human beings, and the atmospheric environment is a natural environment that can be more in line with the normal distribution, this paper proposes a tentative normal distribution model for corrosion prediction calculations. This paper can predict the fatigue life of aircraft structures in corrosive and polluted environments, with an accuracy rate of over 95%.
