| Abstract |
To enhance the impact resistance and energy absorption capacity of traditional hexagonal
honeycomb (THH) structures, a novel bionic progressive gradient hierarchical (BPGH) honeycomb
structure is proposed herein through biomimetic design principles, while systematically considering
the influence of hierarchical factors on structural performance. The energy absorption characteristics
of the BPGH structure are systematically analyzed through finite element analysis and experimental
testing. The results demonstrate that compared with traditional hexagonal honeycomb (THH) structures, the BPGH configuration exhibits significant advantages in reducing peak crash forces and
enhancing energy absorption efficiency. Specifically, the BPGH structure demonstrates superior values in maximum crash force (MCF) and specific energy absorption (SEA) when benchmarked against
THH counterparts. Moreover, BPGH configurations with higher hierarchical levels exhibit lower peak
crash forces (PCF) and reduced load fluctuations, leading to a 23.6% improvement in energy absorption stability and a 17.4% increase in specific energy absorption capacity, thereby significantly enhancing overall energy absorption performance. |
