Corrugated energy absorption structure

Abstract

The invention provides a corrugated energy absorption structure which comprises a plurality of energy absorption columns, and each energy absorption column is formed by splicing a plurality of corrugated units pairwise. Each corrugated unit is formed by splicing two corrugated sheets; An angle is formed between the two corrugated sheets, and each corrugated sheet comprises straight line edges arranged on the upper side and the lower side; a corrugated curved surface is arranged between the two straight line edges, and the side view of the curved surface is a curve. By means of the technical scheme, the energy absorption structure can have high energy absorption capacity in the collision process.

Description

technical field [0001] The invention relates to the field of energy absorption, in particular to a corrugated energy absorption structure. Background technique [0002] In recent years, with the rapid development of the transportation industry, the density of urban networks and logistics networks and the speed of transportation are rapidly increasing. This has brought great challenges to the safety of personnel and objects. In the face of complex and high-speed conditions, the protective structure needs sufficient cushioning and energy absorption performance to protect the safety of occupants and objects. However, the current structures often have high cushioning capacity and low initial stiffness but are not ideal in terms of energy absorption, or are capable of absorbing energy during a collision but have high stiffness, resulting in a large overload at the moment of collision, and there is little protection. The structure can take into account the characteristics of both...

This has brought great challenges to the safety of personnel and objects. In the face of complex and high-speed conditions, the protective structure needs sufficient cushioning and energy absorption performance to protect the safety of occupants and objects.

However, the current structures often have high cushioning capacity and low initial stiffness but are not ideal for energy absorption, or have high stiffness that can absorb and capture energy during a collision, resulting in a large overload at the moment of collision, and there is little protection. The structure can take into account the characteristics of both
