The work aims to study the influence of triangular honeycomb arrangement on the dynamic compression properties in the out-of-plane direction of triangular honeycomb. By means of Ansys/LS-DYNA, a finite element analysis model of triangular honeycomb's out-of-plane dynamic compression based on representative cells was established, and the influence of triangular honeycomb arrangement on the out-of-plane compression properties of triangular honeycomb was studied. Comparing the finite element analysis results of the triangular honeycomb whole cell array model with the theoretical values, it was proved that the finite element model of the triangular honeycomb was reliable. Then, the triangular whole cell array model was compared with the calculated results of the representative cell model used in this study. The results showed that, the calculated results of the two finite element calculation models were consistent, which proved that the selection of the representative cell structure and the establishment of the model in this study were reliable. Different arrangements have no effect on the dynamic peak stress and energy absorption per unit volume of triangular honeycomb in the out-of-plane direction.
