The openable frame beam reinforcing structure comprises a long cross beam A (1) and a long cross beam B (2) which are arranged in the course direction, a longitudinal beam A (3), a longitudinal beam B (4) and a longitudinal beam C (5) are sequentially arranged between the long cross beam A and the long cross beam B in parallel, and a short cross beam A (6), a short cross beam B (7) and a short cross beam C (8) are sequentially arranged between the longitudinal beam B and the longitudinal beam C in parallel. While the weight of the aircraft structure is reduced, the strength and rigidity requirements of the opening structure are met, and a new thought is provided for aviation structure design and optimization.
本发明公开了一种可打开式的框梁加强结构及飞机开口结构,包括一对沿航向设置的长横梁A(1)和长横梁B(2),长横梁A、B间依次平行布置有纵梁A(3)、纵梁B(4)和纵梁C(5),纵梁B、C间依次平行布置有短横梁A(6)、短横梁B(7)和短横梁C(8)。本发明能够在减轻飞机结构重量的同时,满足开口结构的强度和刚度要求,为航空结构设计与优化提供了一种新思路。
