摘要
原型飞机进行改型设计后,由于飞机的重量、重心变化,必将导致改型飞机起落架的载荷发生变化。应用细节疲劳额定值基本方法,利用原型飞机起落架的疲劳试验数据对改型飞机起落架的疲劳强度进行分析,称为起落架细节疲劳额定值方法。该方法较为简单、可靠、实用。
After a modified version design according to the original aircraft, due to the changes of weight and cen- ter of gravity, it can lead to the changes of load on remodeled aircraft landing gear. This paper presents landing gear detail fatigue rating （LGDFR） method to finish the fatigue strength analysis of military aircraft landing gear, used the fatigue test data based on the landing gear detail fatigue rating. The method is simple, reliable and practical.
