Novel honeycomb structure and honeycomb energy absorption piece

Abstract

The invention belongs to the technical field of energy absorption materials, and provides a novel honeycomb structure. The novel honeycomb structure comprises a plurality of honeycomb units, a plurality of honeycomb units are arranged on the periphery of each honeycomb unit, each honeycomb unit comprises at least two hole grids and at least two connecting parts, the hole diameters of the at leasttwo hole grids are different, and the hole grid with the larger hole diameter sleeves the outer side of the hole grid with the smaller hole diameter. A gap is formed between every two mutually nestedhole grids, every two mutually nested hole grids are connected through two connecting parts, and the two connecting parts are respectively positioned on two opposite sides of the hole grid with the smaller hole diameter. The invention further provides a honeycomb energy absorption piece. The honeycomb energy absorption piece have the novel honeycomb structure. According to the novel honeycomb structure and the honeycomb energy absorption piece, the honeycomb units formed by nesting the at least two hole grids are adopted, so that the technical problem that the adjustable range of the strengthof the honeycomb structure is small is effectively solved, the grade of the adjustable strength of the honeycomb structure in actual engineering application is more refined, and the designability is higher.

Description

Technical field [0001] This application belongs to the technical field of energy absorbing materials, and more specifically, relates to a novel honeycomb structure and honeycomb energy absorbing member. Background technique [0002] With the rapid development of China's high-speed rail and urban rail, convenient and efficient rail transportation has become the first choice for many people to travel, and its safety protection is very important. As an important topic in the field of safety protection, collision buffering energy absorption has always attracted wide attention. The field has developed a wide variety of structural forms such as hydraulics, springs, metal cutting, and honeycombs. Among them, the honeycomb energy absorber is light and high-strength. Its advantages are widely used in fields such as automobiles and rail transit. The honeycomb manufacturing process is mainly divided into two types: stretching method and forming method. The stretching method refers to coati...

Problems solved by technology

For ordinary honeycombs, although honeycombs with different strengths can be obtained by adjusting the cell side length and wall thickness, due to the limitations of the thickness of aluminum foil on the market and the limitations of the corrugated sheet forming process, the adjustable range and adjustment distance of the honeycomb strength are very limited.
