The invention belongs to the technical field of energy absorption devices, and discloses a novel biological inspiration DNA lattice structure lateral energy absorption device and application, the novel biological inspiration DNA lattice structure lateral energy absorption device comprises an upper layer flat plate, a lower layer flat plate and a middle layer located between the upper layer flat plate and the lower layer flat plate; the upper-layer flat plate and the lower-layer flat plate are both of a deformable shell type plate structure; the interlayer DNA lattice comprises a plurality of bionic DNAs, and the plurality of bionic DNAs are respectively arranged along the x direction and the z direction of the flat plate to form a 3 * 12 matrix lattice structure. As DNA lattices can absorb a large amount of energy in the stress deformation process, large peak force generated during collision is gradually decomposed by the DNA lattices in the deformation compression process, and the specific energy absorption of the structure is remarkably increased. Due to the fact that the upper panel and the lower panel are made of 45 # steel materials and have high yield strength, the upper panel and the lower panel do not crack in the compression process.
本发明属于能量吸收装置技术领域,公开了一种新的生物启发DNA晶格结构侧向能量吸收装置及应用,包括上层平板、下层平板以及位于上层平板和下层平板之间的中间层;所述上层平板和下平面板均为可变形壳型板结构;所述中间层DNA晶格包括若干仿生DNA,若干仿生DNA分别沿平板x方向和z方向排列放置,组成一3×12的矩阵晶格结构。由于DNA晶格在受力变形过程中可以吸收大量的能量,所以碰撞时产生的较大的峰值力被DNA晶格在变形压缩过程中逐渐分解掉,并且显著增加结构的比能量吸收。由于上下两个面板采用的45号钢材料,具有较高的屈服强度,所以在压缩过程中上下两个面板不会出现裂纹。
