The invention belongs to the technical field of aircraft fuselage curved frame annular bending moment load loading design, and particularly relates to an aircraft fuselage curved frame annular bending moment load loading device and method. Annular bending moment loads are stably applied to the aircraft fuselage curved frame through the transmission beams and the loading beams, in the loading process, the two transmission beams are suspended and are in a free state, and the two loading beams can be driven to rotate, and due to the fact that the axes of the two loading beams connected to the edges of the two sides of the aircraft fuselage curved frame are located on the arc where the aircraft fuselage curved frame is located, the two loading beams can rotate. According to the method, the accuracy of loading the annular bending moment load of the aircraft fuselage curved frame can be guaranteed, and compared with a four-point bending loading mode, the situation that stress concentration is formed in a local area on the aircraft fuselage curved frame and consequently damage is caused in advance can be effectively avoided.

    本申请属于飞机机身曲框环向弯矩载荷加载设计技术领域,具体涉及一种飞机机身曲框环向弯矩载荷加载装置及其方法,利用位于飞机机身曲框内外两侧的加载作动筒伸缩的协同动作,通过传动梁、加载梁平稳的向飞机机身曲框施加环形弯矩载荷,在加载过程中,两个传动梁悬空,处于自由状态,可带动两个加载梁转动,由于连接在飞机机身曲框两侧边缘上两个加载梁的轴线处于飞机机身曲框所在圆弧上,可保证对飞机机身曲框环向弯矩载荷加载的准确性,且相对于四点弯曲加载的方式,可有效避免飞机机身曲框上局部区域形成应力集中发生提前破坏的情形。
