摘要仿生结构/材料是近年来工程领域的研究热点。本文以海岸马尾为灵感，通过引入双箭头拉胀填料，提出了一种新型的夹层圆柱体。对夹层筒的吸能特性进行了全面分析，并与传统结构进行了比较，说明了夹层筒的优越性。讨论了几何参数对吸能特性的影响。研究发现，拉胀结构的层数、单元数、梁和薄壁管的厚度以及内管的半径对压溃力、能量吸收、初始峰值力和比能量吸收有很大的影响。设计后的夹层圆筒将是一种很好的吸能装置。
Abstract Bioinspired structure/material has attracted attentions in engineering fields. In this article, a novel sandwich cylinder inspired by shore horsetail is proposed by introducing the double-arrowed auxetic filler. The energy absorption characteristics of the sandwich cylinder are analysed comprehensively and compared to the conventional structure to show its superiority. The effects of the geometric parameters on the energy absorption characteristics are also discussed. It is found that the number of layers and cells for auxetic structures, thickness of beams and thin-walled tubes, and the radius of the inner tube have great effects on the crushing force, energy absorption, initial peak force and specific energy absorption. The sandwich cylinder will be a great energy absorber after designing.
