Multidirectional bearing honeycomb buffering combined energy absorption structure imitating footballene structure

Abstract

A multidirectional bearing honeycomb buffering combined energy absorption structure imitating a footballene structure comprises an energy absorption box and a honeycomb filling structure, and the honeycomb filling structure is installed in the energy absorption box. The honeycomb filling structure is formed by a plurality of single honeycomb cells similar to the footballene structure in an array attaching and transformation mode along the X axis, the Y axis and the Z axis, in the array process, the intersecting edges of every two adjacent honeycomb cells similar to the footballene structure completely coincide, and the honeycomb cells are obtained by connecting twelve pentagonal trusses and twenty hexagonal trusses and then imitating the footballene structure to form a sphere-like polyhedron array; the buffering performance of a buffer filling material is improved through the honeycomb cell structure, the bearing energy absorption capacity of the buffer filling structure in all directions is effectively enhanced, and compared with a traditional polygonal entity array buffering filling structure, the lightweight design is improved to some extent; and the designed buffering structure is combined with an existing buffering energy absorption box, and the combined energy absorption function is achieved.

Description

technical field [0001] The invention belongs to the technical field of buffer energy-absorbing structures, and in particular relates to a multi-directional load-carrying honeycomb buffer combined energy-absorbing structure imitating a soccer ballene structure. Background technique [0002] Unmanned vehicle technology is still in its infancy, and traffic accidents caused by unskilled unmanned driving technology are common. In order to reduce the damage of drivers and passengers due to impact in traffic accidents, the car body structure needs to be designed with cushioning and crashworthiness . [0003] At present, the buffering and energy absorption of automobiles mainly depends on the outer wall structure of the car body and the energy-absorbing box. Convert part of the energy absorbed into the internal energy of the structure. Among them, the honeycomb structure has been widely used in the field of cushioning and energy absorption due to its advantages of low density, low...
