Evaluation of Energy Absorption Characteristics of Multicellular Structures based on Tachi-Miura Polyhedron

Abstract

Origami structures have been paid attention to realize energy absorption structure with load uniformity. Among origami structures, Tachi-Miura polyhedron (TMP) based cellular structures have unique mechanical properties such as switchable load-bearing capability by transition between collapsible and load-bearing states. This paper investigates energy absorption performance of TMP based cellular structure. The cellular structures are designed to realize collapsible and load-bearing states and fabricated by 3D printer as specimen of impact testing. As a result of the testing, deformation behavior of the cellular structure corresponds to collapsible and load-bearing motions designed based on TMP, which leads to significant energy performance difference. Therefore, we can design the variety of energy absorption performance using TMP based the cellular structures.
