▎ 摘  要

NOVELTY - The structure has a multi-layer annular structure provided with a polygonal structure (1). An adjacent layer is provided with the same configuration from top to bottom, where the adjacent layer includes a torsion angle (3) along a central axis along a clockwise direction of the adjacent layer. Multiple middle connecting rods (2) are connected with the polygonal structure in a front axis direction, where the middle connecting rods are oppositely arranged to a middle shaft line of the multilayer annular structure. The middle connecting rods are connected with a front multi-layer annular structure corresponding to a top point along central axis direction. USE - Pressure-induced torsion graphene-like lattice structure for use in automobile, ship, aerospace field, etc. ADVANTAGE - The structure has higher platform stress, which greatly improves the energy absorption and bearing capacity of the structure. The structure is shown as low poisson ratio characteristic in the compression motion process, so that the structure has good bearing capacity and energy absorption capability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a pressure-induced torsion graphene-like lattice structure three dimensional (3D) printing method. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a pressure-induced torsion graphene-like lattice structure. 1Polygonal structure 2Middle connecting rods 3Torsion angle
