Metamaterial energy absorption structure based on Boolean operation

Abstract

The invention provides a Boolean operation-based metamaterial energy absorption structure, which comprises an energy absorption box, and is characterized in that the energy absorption box consists of a plurality of metamaterial structures; the metamaterial structure is composed of a plurality of metamaterial monomers; a thin spherical shell is arranged in a regular polygon prism, and the vertical distance between the center of the regular polygon prism and each side face and the bottom face of the regular polygon prism is smaller than the radius of the thin spherical shell. Then Boolean operation is carried out on the thin spherical shell and the regular polygon prism in a manner that: the part, which is arranged in the regular polygon prism and overflows out of each side surface and the bottom surface of the regular polygon prism, of the thin spherical shell is an overflow part, and the overflow part of the thin spherical shell is removed to obtain the metamaterial monomer. By applying the technical scheme, lightweight protection and efficient energy absorption of the energy absorption box can be achieved.

Description

technical field [0001] The invention relates to the field of energy-absorbing boxes, in particular to a metamaterial energy-absorbing structure based on Boolean operations. Background technique [0002] In the past ten years, the industrial scale of the transportation industry has gradually expanded, and the transportation mileage, speed and efficiency have been greatly improved, but it has brought considerable challenges to transportation safety and transportation quality. Faced with the continuous improvement of protective safety performance, many protective structures and energy-absorbing results are widely used in various aspects of the transportation industry, so that the protective measures have been effectively guaranteed. However, in the face of complex or extreme environments, such as the complex shape of the protected structure and the working conditions of high-speed collisions, the current protective structure cannot efficiently complete the task of buffering and...
