Abstract

The invention relates to a novel cell honeycomb buffering device capable of improving multidirectional bearing and energy absorbing efficiency. The novel cell honeycomb buffering device comprises a shell and a honeycomb structure plate, wherein the honeycomb structure plate is arranged in the shell and is connected with the shell. The shell comprises side plates, an upper skin and a lower skin. The edges of the upper skin are connected with the edges of the upper portions of the side plates, and the edges of the lower skin are connected with the edge of the lower portion of the side plates. The honeycomb structure plate is of an array structure composed of multiple honeycomb cell structures. Each honeycomb cell structure comprises a hollow regular hexahedron aluminum sheet, a first hollowrectangular trihedron aluminum sheet, a second hollow rectangular trihedron aluminum sheet and a transverse reinforcing rib, wherein the right outer contour of the honeycomb cell structure is formed by the hollow regular hexahedron aluminum sheet, and the first hollow rectangular trihedron aluminum sheet and the second hollow rectangular trihedron aluminum sheet abut against each other to be combined into the left outer contour of the honeycomb cell structure in a cementing manner. The honeycomb cell structures are connected together in an interweaving manner, orthogonal three axis stress canbe borne, and the bearing and energy absorbing capability is achieved at any angle in multiple directions.

Description

technical field [0001] The invention relates to the technical field of buffering and energy absorption, in particular to a cellular honeycomb buffering device that improves the energy-absorbing efficiency of multi-directional bearings. Background technique [0002] Honeycomb structure is a good cushioning material with high specific strength, high specific stiffness and superior specific energy absorption, and is widely used in flight landers, bridge protection devices and passive protection devices for rail vehicles. However, the current traditional configuration of honeycomb aluminum has low specific mass energy absorption, and the working state of buffer energy absorption is only suitable for a single direction. [0003] The load-bearing and energy-absorbing direction of the traditional honeycomb aluminum structure is often in the direction of its different plane, and the array layout of the honeycomb is designed according to the load-bearing direction of the different pl...
