Abstract

In order to improve the energy absorption characteristics of the honeycomb structure under axial compression, this paper combines the diamond origami tubes with the honeycomb structure, and a novel origami-based honeycomb structure with a tight arrangement and close bonding is proposed. By comparing connections of diamond polygonal origami honeycombs with different side numbers, a honeycomb structure consisting of diamond triangular origami tube (DTOT) units is established. Experiments and numerical simulations analyze its deformation mode and energy absorption properties under axial compression, and the parametric analysis is also carried out. Based on the classical folding theory, a prediction formula for the mean crushing force for DTOT honeycomb structures is obtained, and its inaccuracies are within 10 % of experiments and simulation findings. The results show that the DTOT honeycomb structure can effectively reduce the initial peak crushing force while maintaining the SEA, and has a good prospect for cushioning and energy absorption applications compared with conventional multicellular and honeycomb structures.

金刚石折纸管蜂窝结构轴向压缩性能研究

为了提高蜂窝结构在轴向压缩下的吸能特性，本文将金刚石折纸管与蜂窝结构相结合，提出了一种排列紧密、键合紧密的新型折纸蜂窝结构。通过比较不同边数的菱形折纸蜂窝的连接，建立了由菱形三角形折纸管（DTOT）单元组成的蜂窝结构。实验和数值模拟分析了其轴向压缩下的变形模式和能量吸收特性，并进行了参数化分析。基于经典折叠理论，得到了dot蜂窝结构平均破碎力的预测公式，其与实验和仿真结果的误差在10 %以内。结果表明，DTOT蜂窝结构在保持SEA的同时，能有效降低初始峰值破碎力，与传统的多蜂窝结构和蜂窝结构相比，在缓冲和吸能方面具有良好的应用前景。
