Beetles have developed the elytra that are interesting and impressive strategy for thriving in their native environments. The elytra, although formed from simple biopolymer constituents, take on many effective designs. In present work, internal structure of elytra is discussed and three bionic structures named as the bio-inspired honeycomb column thin-walled structure (BHTS) are proposed. Then the crushing behavior and energy absorption characteristics of the BHTS under axial impact loading are investigated by numerical simulation. This study reveals not only the relationship between the adding mode and energy absorption characteristics, but also the influence of column diameter on the BHTS. The findings show that the BHTS represents a significant improvement over honeycomb structures and show potential applications in the field of protective equipment.

甲虫开发了elytra，这是在其原生环境中蓬勃发展的有趣且令人印象深刻的策略。鞘翅目虽然由简单的生物聚合物成分形成，但却具有许多有效的设计。在目前的工作中，elytra的内部结构进行了讨论，并提出了三种仿生结构，称为生物启发蜂窝柱薄壁结构（BHTS）。然后通过数值模拟研究了BHTS在轴向冲击载荷下的破碎行为和能量吸收特性。这项研究不仅揭示了添加方式与能量吸收特性之间的关系，还揭示了色谱柱直径对BHTS的影响。
