A coupling bionic anti-explosion energy-absorbing board and human body protection device or auto parts

Abstract

The invention discloses a coupled bionic anti-explosion energy-absorbing board, which comprises multi-layer substrates sequentially arranged at intervals along the thickness direction of the energy-absorbing board, a plurality of energy-absorbing unit cells arranged between every two adjacent layers of substrates, and Filling in the cavity formed between the energy-absorbing unit cell and two adjacent substrates, each energy-absorbing unit cell includes a first contour line and a second contour line, and each energy-absorbing unit cell has In the central plane, the first contour line is arranged symmetrically with respect to the central plane, and the second contour lines are arranged symmetrically on opposite sides of the central plane, and the energy-absorbing unit cell also includes the second contour line and the first contour line respectively connected on both sides The transition curve between the ends of the line, the first contour line satisfies the curve equation y = -0.021x 2 +0.113x+25.31, the second contour line satisfies the curve equation y=‑2.315x 2 +3.722x+6.398. The coupled bionic anti-explosion energy-absorbing plate has a simple structure, and the cross-sectional profile of the energy-absorbing unit cell is similar to the shape of a pine cone, and has a good buffering and energy-absorbing effect, thereby ensuring the safety of the protected vehicle, equipment inside the vehicle and occupants.

Description

technical field [0001] The invention relates to the technical field of explosion impact protection, in particular to a coupled bionic anti-explosion energy-absorbing plate and a human body protection device or an automobile part. Background technique [0002] Since the outbreak of the Iraq War in 2003, the war mode has changed from armored group confrontation to small-scale, low-intensity asymmetric operations. Anti-US armed forces have used improvised explosives to cause a large number of casualties to the US military. The loss of military vehicles caused by the explosion accounted for about 20% of the total, and in some campaigns this proportion was close to 40%. At present, the second- and third-generation military vehicles developed by our country have not considered explosion-proof capabilities at present. At the same time, due to the shock response caused by the explosion, there are more and more cases of secondary injuries. In these cases, the shock effect produced b...

AI Technical Summary

Problems solved by technology

At present, the second-generation and third-generation military vehicles developed by my country have not considered explosion-proof capabilities, and the structural characteristics of explosion-proof armored vehicles and the protection of personnel in the vehicles are also in the initial stage.

At the same time, due to the shock response caused by the explosion, there are more and more cases of secondary injuries. In these cases, the shock effect generated by the explosion will cause various irreversible damage to personnel and equipment.

[0003] At present, although various protective seats, headrests and other devices have appeared in China, most of them adopt traditional design ideas, such as complex mechanical linkage mechanisms, spring mechanisms, hydraulic mechanisms, and slide rail mechanisms, which are not only costly, but also occupy a large area. Disadvantages such as large space and heavy weight
