The invention belongs to the field of aircraft structure design, and particularly relates to a stiffened wall plate butt joint structure and a design method. The structure comprises a first stiffened wall plate and a second stiffened wall plate, wherein the first stiffened wall plate comprises a first skin and first ribs arranged on the first skin; the second stiffened wall plate comprises a second skin and a second rib arranged on the second skin; wherein the first skin and the second skin are connected through bolts; the first rib and the second rib are connected through a butt joint assembly. The rib butt-joint areas and the skin butt-joint areas are arranged in a staggered mode, and the two rib butt-joint areas are located on the two sides of the skin butt-joint areas correspondingly. The multi-path force transmission butt joint mode is adopted, the skin and the ribs are in scattered butt joint, continuous structural rigidity and continuous load transmission are kept, large stress concentration and weight cost are avoided, and fatigue details at the butt joint position are facilitated.
本申请属于飞机结构设计领域,特别涉及一种加筋壁板对接结构及设计方法。结构包括:第一加筋壁板,所述第一加筋壁板包括第一蒙皮以及设置在所述第一蒙皮上的第一筋条;第二加筋壁板,所述第二加筋壁板包括第二蒙皮以及设置在所述第二蒙皮上的第二筋条;其中,所述第一蒙皮与所述第二蒙皮通过螺栓连接;所述第一筋条与所述第二筋条通过对接组件连接;筋条对接区与蒙皮对接区进行错位布置,两个所述筋条对接区分别位于所述蒙皮对接区的两侧。本申请采用多路传力对接形式,蒙皮、筋条分散对接,保持结构刚度连续、载荷传递连续,避免较大的应力集中和重量代价,且有利于对接处的疲劳细节。
