收放载荷对某型飞机起落架安装结构耐久性影响分析

Analysis of the Influence of Retraction/Extension Load on the Durability of an Aircraft Landing Gear Mounting Structure

某型飞机起落架安装接头裂纹问题频发,通过对比耐久性分析中载荷谱是否考虑起落架收放载荷作用,发现该型飞机收放载荷引起的接头损伤占据较高的比例,需引起重视。

The mounting point of a certain type of aircraft cracks frequently.By comparing the load spectrum in the durability analysis for whether the landing gear retraction/extension load is considered,it is found that the damage of the mounting point caused by the retraction/extension load accounts for a higher proportion on this type of aircraft,which should be paid attention to.
