Honeycombs are extensively utilized as energy absorber due to their stabilized mechanical properties. Therefore, we propose a novel symmetry-corrugate hierarchical design strategy to construct symmetry-corrugate hierarchical honeycombs (SCHH). Crashworthiness and mechanical properties of SCHH are investigated by experiments and numerical simulation. SCHH exhibits a stable and efficient mechanical property in the compression test. Furthermore, numerical simulations have been conducted to investigate the parametric design of SCHH. The results show the effects of different period coefficients φT and amplitude coefficients φA on deformation modes and crashworthiness. Specifically, as φT increases and φA decreases, the deformation changes from progressive deformation mode (P-mode) to mixed deformation mode (M-mode) to global bending deformation mode (G-mode). P-mode and M-mode have better crashworthiness. The effect of φT on the crashworthiness of SCHH is more significant than φA. In addition, SCHH provides the highest crashworthiness compared with other honeycombs. Specifically, the energy absorption capacity and crushing stability are improved by 53.8 % and 68.5 %, respectively, compared with conventional honeycomb. Eventually, a crashworthiness prediction model of SCHH is developed by machine learning algorithms, and the model is verified to have high accuracy. In this study, the proposed strategy and methods are expected to further improve the crashworthiness of honeycomb.
