This study introduce an innovation okra biomimetic corrugated multi-cellular Taper tube (OBCMT) designed for the energy absorption, drawing inspiration from the okra, which comprises a Fourier curve wall and X-shaped ribs. Validation is accomplished through quasi-static crushing experiments, ensuring the accuracy of the finite element simulation model. Numerical simulations investigate the influence of critical interaction structural parameters on the performance of the OBCMT, and a theoretical model based on the super folding theory is deduced to predict the mean crushing force of the OBCMT. The result show that the specific energy absorption() exhibited the heightened sensitivity to the variation of under the same _, approximately reached 8.36 kJ/kg which increased by 43.2 % compared to the minimum value in the identical group. Simultaneously, the structure parameters of height coefficient() and radiu coefficient() have the most significant impact on the deformation mode of OBCMT. Comparative analysis demonstrates that the OBCMT exhibits the extraordinal crashworthiness compared to the contemporary typical energy absorption structures under identical mass, with the reaching 21.8 kJ/kg. This represents approximately 290.7 %, 205.7 %, 187.9 %, 189.6 %, and 174.4 % relative to the six-cell hexagonal tube (SHT), quadruple-cell circular tube (QCT), multi-cell bicircular tube (MBT), five-cell square tube (FST), and quadruple-cell square tube II (QST_Ⅱ), respectively. This research significantly advances the development of high-performance bionic energy-absorbing structures for crash applications and enhances our comprehension of the biomimetic engineering.

黄秋葵仿生波纹多细胞结构耐撞性分析


本研究介绍了一种创新的秋葵仿生波纹多细胞锥形管（OBCMT），其设计用于能量吸收，从秋葵中汲取灵感，它包括傅里叶曲线壁和X形肋。通过准静态破碎实验完成验证，保证了有限元仿真模型的准确性。数值模拟研究了关键相互作用结构参数对OBCMT性能的影响，并推导了基于超折叠理论的理论模型来预测OBCMT的平均压溃力。结果表明，比能量吸收()对相同_下的变化表现出较高的敏感性，约达到8.36 kJ/kg，比同组中的最小值增加了43.2%。同时，高度系数()和半径系数()等结构参数对OBCMT的变形模式影响最为显着。对比分析表明，在相同质量下，OBCMT与当代典型吸能结构相比表现出非凡的耐撞性，达到21.8 kJ/kg。相对于六单元六角形管 (SHT)、四单元圆形管 (QCT)、多单元双圆形管 (MBT)、五单元，这表示大约 290.7%、205.7%、187.9%、189.6% 和 174.4%。分别为单元方管（FST）和四单元方管II（QST_Ⅱ）。这项研究极大地推进了用于碰撞应用的高性能仿生能量吸收结构的开发，并增强了我们对仿生工程的理解。
