摘要

为提高蜂窝结构的吸能稳定性,基于星形蜂窝结构(SSH:star-shape honeycomb),采用箭头代替其水平壁,并引入与四个凹角接触的方形薄壁,构建了一种改进星形蜂窝结构(ISSH:improved star-shape honeycomb)。基于冲击波理论,确定了改进星形蜂窝的低、中、高压溃速度的范围。基于有限元仿真分析了不同冲击速度下的变形模式和吸能特性。结果表明,在不同的冲击载荷下,ISSH具有更高的比能量吸收。基于典型单元的变形特征,构建了理论分析模型,基于能量守恒与动量守恒得到了其在低速和高速加载下的平台应力,理论计算与数值模拟结果呈现出较好的一致性。结果表明:与SSH相比,箭头形和方形薄壁结构的引入提高了ISSH变形的稳定性,ISSH具有更强的吸能能力。研究结果有助于抗冲击防护结构设计。

Abstract

To improve the energy absorption stability of the honeycomb structure. Based on the star-shape honeycomb structure (SSH: star-shape honeycomb), an arrow was used to replace its horizontal wall, and a thin-walled square contacting four concave corners was introduced to construct an improved star-shape honeycomb (ISSH: improved star-shape honeycomb). Based on the one-dimensional shock wave theory, three different crushing velocities of the improved star-shaped honeycomb were determined. The deformation mode and energy absorption characteristics under different impact velocitys were analyzed by finite element simulation. Based on the deformation characteristics of typical elements, a theoretical calculation model was constructed, and the plateau stress under low-velocity and high-velocity loading was obtained according to the principle of energy conservation and momentum conservation, respectively. The theoretical calculation and numerical simulation results showed good agreement. The results showed that, compared with SSH, the addition of arrow-shaped and square structures greatly increased the stability of ISSH deformation. And ISSH had a stronger energy absorption capacity. The present results are significant for the design of impact protective structures.
