To enhance the impact resistance of honeycomb structures, this article proposes a novel self-similar nested structure (SNHRH) by incorporating ribs within framework. Finite element simulations and experimental validations were conducted using Abaqus software. The results from out-of-plane crushing tests demonstrate that SNHRH exhibits superior energy absorption capabilities compared to conventional hierarchical multifunctional chiral metamaterials, spider-web honeycombs. Furthermore, enhanced characteristics SNHRH-1 are not merely attributable incorporation internal cytokinetic elements; rather, they arise interactions among these components, which result in more pronounced plastic deformation at intersections. further elucidate geometric parameters on crashworthiness proposed structure, study analyzes significant effects relative density, rib angle, thickness ratio distribution. accuracy finite simulation was verified through compression tests. findings indicate density is positively correlated with absorption, specific initial peak crash force, force efficiency. An increase corresponds higher while maintaining constant wall thickness. Notably, same type orders exhibit improved performance. Specifically, SNHRH-4 found be 88.63% greater than SNHRH-1.
