Embodiment 1
[0026] Referring to Fig. 2(a), the vulnerable area 1 such as sudden change in stiffness of the cylindrical shell structure is the action area of the concentrated force condition. With this area as the center of symmetry, gradient distributed reinforcement 3 is arranged on the skin 2 along the circumferential direction. The reinforced section shape is rectangular and the material property is composite. The gradient distribution description method followed by the reinforcement is an exponential function, that is, the size of the i-th reinforcement compared to the i-1-th reinforcement (including variables such as web height and web thickness) and layout information (i.e. The distance between the strip and the reference rib) shows an exponential function change trend, where i=1,2,...,N.
Embodiment 2
[0028] Referring to Fig. 3(a), the vulnerable area 1 such as sudden change in rigidity of the cylindrical shell structure is a weld seam, and with this area as the center of symmetry, gradient distributed reinforcement 3 is arranged on the skin 2 along the circumferential direction. The reinforced section shape is T-shaped, and the material property is metal aluminum alloy. The gradient distribution description method followed by the reinforcement is a sine function, and the size of the i-th reinforcement compared to the i-1th reinforcement (including web height, web thickness, flange width, flange thickness, etc. variable) and the layout information (that is, the distance between the rib and the reference rib) have a sinusoidal function variation trend, where i=1, 2,...,N.
Embodiment 3
[0030] Referring to Fig. 4(a), the vulnerable area 1 such as the abrupt change in rigidity of the cylindrical shell structure is a weakening groove, and with this area as the center of symmetry, gradient distributed reinforcement 3 is arranged on the skin 2 along the axial direction. The shape of the reinforced section is rectangular, and the material property is metal aluminum alloy. The gradient distribution description method followed by the reinforcement is a linear function, that is, the size of the i-th reinforcement compared to the i-1-th reinforcement (including variables such as web height and web thickness) and layout information (i.e. The distance between the strip and the reference rib) shows a linear function change trend, where i=1, 2,...,N.
