Several bamboo features are responsible for its known mechanical performance and thus were applied on bionic thin-walled structures, still the particular geometry of individual vascular bundles remains unexplored mechanically. This research investigates the mechanical influence of that region in the design of thin-walled structures, comparing it with bamboo-inspired designs from the literature. X-ray microtomography was used to explore bamboo bundle's geometry, applying it as reinforcement. The proposed new design showed improvements in strength and energy absorption in axial, lateral, and flexural explicit Finite Element Analyses. The vascular bundle's geometry was revealed as an important characteristic of bamboo performance.

几个竹子特征是其已知的机械性能的原因，因此被应用于仿生薄壁结构上，但单个血管束的特殊几何形状仍未进行机械探索。这项研究调查了该区域在薄壁结构设计中的机械影响，并将其与文献中以竹为灵感的设计进行了比较。X射线显微照相术被用于探索竹束的几何形状，并将其用作增强材料。所提出的新设计在轴向，横向和弯曲的显式有限元分析中显示出强度和能量吸收方面的改进。血管束的几何形状被揭示为竹性能的重要特征。
