Abstract

The invention belongs to the field of passive safety protection, and relates to a thin-wall pipe, in particular to a folded paper type thin-wall pipe. The problems of irregular deformation and poor force stability of a common thin-wall pipe during compression are solved. The folded paper type thin-wall pipe comprises a plurality of single-layer folded paper circular rings, wherein the plurality ofsingle-layer folded paper circular rings are sequentially connected along the axial direction to form a pipe body.

Description

technical field [0001] The invention relates to a thin-walled tube, in particular to an origami-type thin-walled tube, which belongs to the field of passive safety protection. Background technique [0002] With the rapid development of China's high-speed rail and urban rail, convenient and efficient rail transit has become the first choice for many people, and its safety protection is very important. Buffer energy-absorbing devices in the field of rail trains mainly include honeycomb, expanding tubes, shrinking tubes, planing tubes, and thin-walled structures. The thin-walled structure has been widely used due to its advantages of high specific strength, light weight, simple manufacture, and low cost. Thin-walled tubes mainly bear axial loads in the buffer energy-absorbing system. The thin-walled tube will undergo large plastic deformation under the action of axial impact, and convert the impact kinetic energy into plastic deformation energy of the metal and dissipate it, ...
