Honeycomb energy absorption structure and preparation method of absorption structure

Abstract

The invention provides a honeycomb energy absorption structure and a preparation method of the absorption structure, and relates to an energy absorption structure and a preparation method of the absorption structure. The honeycomb energy absorption structure and the preparation method of the absorption structure aim at solving the problems that an existing simple energy absorption structure is confined to single direction design and cannot adapt to impact conditions with the direction change, and in a complex energy absorption structure, the difficulty of the process manufacturing flow is increased, and the energy absorption capacity in unit mass is reduced. The honeycomb energy absorption structure comprises multiple energy absorption assemblies. The multiple energy absorption assembliesare arranged side by side in parallel to form the honeycomb energy absorption structure. The method is achieved through the following steps that 1, aluminum alloy or stainless steel metal plates are cut through the linear cutting technology; 2, the plates cut in the step 1 and annular pipe bodies are sequentially cleaned, subjected to oil stain removal and subjected to rust removal; 3, cross plates are welded to the inner side walls of ring bodies, and the energy absorption assemblies are manufactured; and 4, the multiple energy absorption assemblies prepared in the step 3 are arranged rectangularly. The honeycomb energy absorption structure and the preparation method of the energy absorption structure are used in the field of energy absorption structures.

Description

technical field [0001] The invention relates to an energy absorbing structure and a preparation method of the absorbing structure, in particular to a honeycomb energy absorbing structure and a preparation method of the absorbing structure. Background technique [0002] The energy absorbing structure is a common safety protection device and is widely used in In large-scale industrial engineering fields such as aerospace, vehicle engineering, and ocean engineering, the occurrence of impact collision accidents has been avoided, and casualties and property losses have been reduced or reduced. At present, the structure of honeycomb energy absorbing unit cell has developed from simple quadrilateral, hexagonal and ring to complex rotational quadrilateral and chiral structure. Although these structures can control Poisson's ratio, they reduce the energy absorption capacity per unit mass. The complex energy-absorbing structure increases the difficulty of the manufacturing process. ...
