摘要：
Enlightened by horsetail plant, a bionic self-similar hierarchical honeycomb structure is proposed in this paper. Based on the finite element model verified by test, the crashworthiness performance of the novel and traditional honeycomb structures under multi-angle oblique collision conditions are comparatively analyzed, including deformation modes, stress-strain curves and energy absorption characteristics. The results show that the self-similar hierarchical honeycomb structure has stable deformation mode under both ideal frontal and oblique impact conditions, and stable and excellent energy absorption performance when the impact angle changes. © 2022, Society of Automotive Engineers of China.
