构架式主起落架连接结构是当前民用飞机选用的一种主要主起落架连接结构形式。由于主起落架通常承受着较大的地面载荷工况,这些载荷工况对外翼主翼盒的设计影响较大。本文通过分析主起落架载荷的传力情况,根据主翼盒设计特点,研究分析构架式主起连接结构对主翼盒结构的设计影响,以用于指导起落架结构设计。
The structure main landing gear connection structure is one of the main main landing gear connection structures used in civil aircraft. Since the main landing gear usually suffers from large ground load conditions, these load conditions have a greater impact on the design of the outer wing main wing box. Based on the design features of the main wing box, this paper analyzes the design load of the main landing gear and analyzes the design influence of the main frame connecting structure on the structure of the main wing box so as to guide the design of the landing gear structure.
