Investigation on impact resistance of hierarchical lightweight lattice structure

Abstract This paper is majorly discussing the impact resistance of hierarchical lightweight lattice structure. Firstly, unit cells pyramidal structure and traditional single-stage hollow are designed. At same time, concept relative density introduced to better demonstrate In this paper, ABAQUS/Explicit software used simulate drop hammer simulation The result shows that than Meanwhile, samples prepared by 3D printing, then quasi-static compression experiment carried out. It concluded bearing performance has obvious improvement under both low-speed impact.
