Embodiment Construction
[0043] Below by specific embodiment the present invention is described in further detail:
[0044] see figure 2 , which is a structural schematic diagram of the fuselage panel composite load strength test device of the present invention. The fuselage panel composite load strength test device is mainly composed of annular rubber pad 1, corner box 2, airtight end plate 3, hinge 5, ejector rod 6, keel 7, curved rubber plate 8, pressure joint 9, Nine parts such as the manhole cover plate and the fuselage wall plate 4 are assembled through bolt connection or adhesive connection.
[0045] Such as image 3 As shown, the fuselage panel refers to a fuselage structure selected from the fuselage cylinder including 5 to 9 stringers, 5 frames and a piece of skin.
[0046] The application of compound load means that one, two or three of internal pressure load, tension (or compression) load and shear load can be applied. Because the tensile load and the compressive load cannot be applie...
