The invention discloses a test loading device, which is used for loading a fuselage structure test piece of an aircraft, and can enable the test loading condition of a curved frame to be closer to the real condition, thereby improving the test loading precision. The fuselage test piece comprises a curved-surface-shaped skin and a curved frame configured along the surface of the skin, the test loading device comprises normal loading pieces, and the normal loading pieces are configured to be symmetrically connected to the curved frame so as to load the curved frame in the first normal direction; the first normal direction is the normal direction of the part, connected with the curved frame, of the normal loading piece of the curved surface where the skin is located, the test loading device further comprises a first annular loading piece, and the first annular loading piece is constructed to be symmetrically connected with a pair of edge parts of the skin so as to load the skin in the first tangential direction; and the first tangential direction is a tangential direction of the curved surface where the skin is located and orthogonal to the edge portion of the skin.

    一种试验加载装置,用于对飞机的机身结构试验件进行加载,能够使曲框的试验加载条件更接近真实情况,从而提高试验加载的精度。机身试验件包括曲面形状的蒙皮和沿着蒙皮的表面配置的曲框,试验加载装置包括法向加载件,法向加载件构造成对称地连接于曲框,以沿着第一法线方向对曲框进行加载,第一法线方向是蒙皮所在的曲面的、法向加载件与曲框连接的部位处的法线方向,试验加载装置还包括第一环向加载件,第一环向加载件构造成对称地连接于蒙皮的一对边缘部,以沿着第一切线方向对蒙皮进行加载,第一切线方向是蒙皮所在的曲面的、与蒙皮的边缘部正交的切线方向。
