The invention relates to the technical field of automobile passive safety protection, in particular to a bionic hierarchical multi-cell pipe energy absorption structure which comprises a multi-cell circular pipe and bionic hierarchical structure units, the multi-cell circular pipe is composed of five partition plates and a circular pipe, and the multi-cell circular pipe with five cell elements is formed; each bionic hierarchical structure unit is composed of triangular hierarchical units, a triangle is formed by connecting the midpoints of two partition plates of each cell element and the midpoints of corresponding arcs, and the triangular hierarchical units are formed by parity of reasoning; the triangular hierarchical units are distributed in each cell element in a gradient mode from large to small in the radial direction, and the triangular hierarchical units of the adjacent cell elements are connected with each other. The bionic hierarchical multi-cell pipe energy absorption structure is stable in deformation in the collision compression process, the platform force fluctuation range is small, collision force can be effectively absorbed, and the safety of passengers is protected. According to the bionic hierarchical multi-cell tube energy absorption structure provided by the invention, under the condition that the structural quality is not changed, the energy absorption characteristic is increased along with the increase of hierarchical orders.

    本发明涉及汽车被动安全防护技术领域,具体为一种仿生层级多胞管吸能结构,包括多胞圆管和仿生层级结构单元,多胞圆管由五个隔板和一个圆管构成,形成具有五个胞元的多胞圆管;仿生层级结构单元由三角形层级单元构成,通过连接每个胞元两个隔板的中点及对应弧线的中点构成一个三角形,以此类推形成三角形层级单元;所述三角形层级单元沿径向由大到小呈梯度分布在每个胞元中,相邻胞元的三角形层级单元互相连接。本发明提供的仿生层级多胞管吸能结构在碰撞压缩过程中变形稳定,平台力波动幅度小,能够有效的吸收碰撞力,保护乘员安全。本发明提供的仿生层级多胞管吸能结构在保证结构质量不变的情况下,能量吸收特性随着层级阶次的增加而增加。
