To improve the impact resistance of metal honeycomb structures, three new types of impact protection structures, namely, closed bent honeycomb, concave filled honeycomb, and star-shaped curved honeycomb, were proposed and analyzed via finite element simulations using ANSYS/LS-DYNA. The deformation patterns and energy absorption capacities were evaluated at different impact velocities. Results showed that deformation patterns were related to the cell element structure and impact velocity. The closed bent honeycomb exhibited superior nominal stress and energy absorption efficiency compared to the other structures. Geometric parameters of honeycomb cell elements do not affect the trend of the nominal stress-strain curves. Increasing the bending angle of the closed bent honeycomb increased platform stress and decreased dense strain. Under medium-velocity impact, the platform stress of the 60° closed bent honeycomb structure increased by 19.5% compared to the 45°structure. Increasing relative density significantly improved energy absorption efficiency; the specific energy absorption of the high-density 60°closed bent honeycomb structure increased by 207.6% compared to the low-density structure.
