Embodiment 1
[0049] This embodiment proposes a box segment docking assembly for different load levels, such as Figure 4 ~ Figure 8 As shown, the docking assembly is used in the box section test field of different load levels in the aircraft body, and the docking assembly includes:
[0050] A number of segmented corner boxes for connecting adjacent butt stringers;
[0051] One and several belt plates 13 that realize the double shear structure inside and outside the block-type corner box;
[0052] A number of angle pieces 16 for connecting the body box section spar 8 and the inside of the dummy box section spar 7; and,
[0053] A number of outer corner boxes 18 that realize a double-shear structure with the inside and outside of the corner piece 16 .
[0054] The block-type corner box is a U-shaped corner box 15 .
[0055] The butt joint stringer is obtained after the body box segment stringer 9 is docked with the dummy box segment stringer stringer.
[0056] Corresponding through holes f...
Embodiment 2
[0068] This embodiment provides the application of a box segment docking method for different load levels as described in Embodiment 1, and the box segment docking method is applied to box segment tests at different load levels, especially large load levels, to reduce assembly difficulty and Experimental risk.
