摘要:

在民用飞机机身上通常布置较多舱门开口,导致机身结构刚度发生急剧变化。为了保证飞机结构刚度以及载荷的传递,本文对机身开口结构的刚度及强度进行了深入研究,明确了开口结构刚度的影响因素,并对开口角度大小及加强结构尺寸进行了优化。以上研究对机身开口结构设计及加强提供了方向和方法,可以用于飞机机身开口结构初步设计阶段。

关键词: 机身, 刚度, 开口区角度, 优化分析

Abstract:

The cabin door openings are usually arranged in the fuselage for civil aircraft, resulting in fuselage stiffness discontinuity. In view of the structural stiffness and the transmission of the load, the paper studies the opening structure of the fuselage: clarifying the factors affecting the stiffness of the opening structure and optimizing the opening angle and the size of the reinforcing structure. The above research shows the direction and the method of the design and the reinforcement of the opening structure in the preliminary design stage of the opening structure of the aircraft fuselage.

Key words: fuselage, stiffness, opening angle, optimization analysis
