A kind of honeycomb energy absorbing structure and the preparation method of absorbing structure

Abstract

A honeycomb energy absorption structure and a preparation method of the absorption structure, the present invention relates to an energy absorption structure and a preparation method of the absorption structure, in order to solve the problem that the existing simple energy absorption structure is limited to a single direction design, cannot adapt to the impact conditions of the direction change, and is complex. The energy absorbing structure increases the difficulty of the manufacturing process and reduces the energy absorbing capacity per unit mass. It includes a plurality of energy absorbing components, and the plurality of energy absorbing components are arranged side by side and parallel to form a honeycomb energy absorbing structure. The method is realized according to the following steps. Step 1: Cut the aluminum alloy or stainless steel metal plate by wire cutting technology; Step 2: Clean, remove oil stains and rust from the plate and annular pipe body cut in Step 1; Step 3: Cut the 'ten' The '-shaped cross plate is welded on the inner side wall of the annular body to obtain the energy absorbing assembly; Step 4: Arrange the plurality of energy absorbing assemblies obtained in the third step in a rectangular arrangement, and the present invention is used in the field of energy absorbing 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. ...
