According to a design method of a split type energy absorption structure, the energy absorption structure can achieve adjustment of energy absorption and change of buffering force through difference of fiber winding, the number of layers, the wire diameter and the material of a composite material energy absorption pipe. Meanwhile, a protruding cut-off tool is arranged in the composite material energy absorption structure and used for cutting composite material fibers, so that compared with a metal planing energy absorption device, a metal pipe expansion energy absorption device and a metal pipe contraction energy absorption device, variable-force-value energy absorption can be achieved. The material is low in density and light in weight. The energy absorption structure has the advantages of being controllable in energy absorption and convenient in buffering force design.

    一种割裂式吸能结构的设计方法,该吸能结构能够通过复材吸能管纤维绕线、层数、线径和材料的不同,实现吸能量的调整和缓冲力变化。同时,该复材吸能结构内部具有凸起的切断刀,用于割裂复材纤维,因此与金属刨削吸能,金属胀管、缩管吸能器比,可以实现变力值吸能。材料密度小,质量轻。该吸能结构具有吸能量可控,缓冲力设计方便的特点。
