摘要

摘要: 金属薄壁管作为吸能结构被广泛应用于汽车等运载工具中，提高薄壁管的吸能特性对于提升运载工具的被动安全具有重要意义。为此，提出了结合多角和多胞结构的单波纹多胞管和双波纹多胞管，采用数值模拟方法研究了波纹幅值和波纹峰数对吸能性能的影响。研究发现，相比传统方形多胞管，波纹多胞管的能量吸收得到显著提高。双波纹多胞管比单波纹多胞管具有更加稳定的变形和更高的能量吸收。选取吸能最优的结构，研究了加强筋位置和节点强化对吸能性能的影响。结果表明：边对边连接的双波纹多胞管的吸能特性最好；在加强筋处进行节点强化可以进一步提高双波纹多胞管的能量吸收。相比传统方形多胞管，节点强化的双波纹多胞管的能量吸收增加了88.17%，压溃力效率提高了65.91%。节点强化的双波纹多胞管比传统多胞管具有更加优异的吸能特性，作为耐撞性结构具有广阔的应用前景。

Abstract: Metal thin-walled tubes are widely used in vehicles as energy absorption structures. Improving the energy absorption characteristics of thin-walled tubes is of great significance for enhancing the passive safety of transportation vehicles. In this paper, a combination of multi-corner and multi-cell structures of single and double corrugated multi-cell tubes were proposed. The influence of corrugation amplitude and corrugation number on the energy absorption characteristics of the corrugated multi-cell tube were studied by numerical method. It was found that the energy absorption of the corrugated multi-cell tube is improved compared with that of traditional square multi-cell tube. In addition, the double corrugated multi-cell tube has a more stable deformation and a higher energy absorption than the single corrugated multi-cell tube. Finally, the optimal structure was selected to study the influence of rib position and node reinforcement. The results show that the edge-to-edge connection has the best energy absorption characteristics, and the node reinforcement at the rib could further improve the energy absorption of the double corrugated multi-cell tube. Compared to traditional square multi-cell tube, the energy absorption of node-strengthened double corrugated multi-cell tube increases by 88.17%, and the crushing force efficiency increases by 65.91%. The node-strengthened double corrugated multi-cell tube has better energy absorption characteristics than traditional square multi-cell tube, leading to broad application prospects as crashworthiness structures.
