Embodiment Construction
[0027] see Figure 1 to Figure 8 As shown, a thin-walled conical energy-absorbing box imitating a yak horn structure is composed of a bionic ribbed tube 1, a bionic inner tube 2, an inner and outer foamed aluminum layered tube 3, an outer layer of foamed aluminum 5, and an inner layer of foamed aluminum 6 Composed of connecting rib 4. The bionic ribbed tube 1 is designed based on the strip-shaped protrusions on the surface of the yak horn shell along the length direction, and the cross-sectional size gradually increases from top to bottom, which has a good step-by-step energy dissipation effect. The bionic inner tube 2, the outer layer of aluminum foam 5, the inner layer of aluminum foam 6 and the inner and outer layers of aluminum foam separating tube 3 are combined to form a bionic core body filled with foam aluminum, which is divided into high-density aluminum foam and low-density aluminum foam The two parts of foamed aluminum are designed to imitate the change of yak horn...
