Abstract

To address the limitations in load-bearing and energy absorption of traditional lattice structures, a bio-inspired conical spiral lattice structure was designed based on the impact resistance of goat horns. Numerical simulations were employed to compare its quasi-static compressive properties with the BCC structure and investigate the effects of relative density (20%–50%). The results indicate that the initial peak stress and specific energy absorption of the bio-inspired structure increased by 205.7% and 171.2%, respectively, compared to the BCC structure. With the increase of relative density, the structural strength exhibits non-linear growth, while the failure mode transitions from ductile yielding to brittle collapse. Comprehensive analysis suggests that a relative density of 40% offers the optimal balance between strength and energy absorption stability.
