Abstract
The invention discloses a sleeving type energy-absorption auxiliary component for a thin-wall pipe. The sleeving type energy-absorption auxiliary component for the thin-wall pipe comprises a plurality of layers of energy-absorption assemblies. The energy-absorption assembly on each layer is composed of energy-absorption elements. The energy-absorption assembly on the outermost layer is composed of one energy-absorption element. In every two adjacent layers of energy-absorption assemblies, the number of the energy-absorption elements of the energy-absorption assembly on the inner layer is double the number of the energy-absorption elements of the energy-absorption assembly on the outer layer; when the number of the energy-absorption elements of the energy-adsorption assembly on the same layer is two or more, the energy-adsorption elements are arranged in a spaced mode; the energy-absorption elements located on the outer layer are nested and adhere to every two adjacent energy-absorption elements on the inner layer; and the portions, bearing an impact load, of the thin-wall pipe are sleeved with the energy-absorption assemblies. Compared with the prior art, the sleeving type energy-absorption auxiliary component for the thin-wall pipe has the advantage that the space in the pipe and the circulating performance are not affected. Through the mutual transmission between the assemblies on all the layers, the external impact load is evenly distributed to the thin-wall pipe so as to be reduced by half, and thus the internal force exerted on the thin-wall pipe is remarkably reduced.
Description
Technical field
The present invention relates to collision prevention of vehicle structure, particularly relate to a kind of jacket-type thin-wall pipe
Energy-absorbing auxiliary.
Background technology
Thin-wall pipe is widely used in automobile, aviation and ship as a kind of main crashproof component
The fields such as oceangoing ship.Under normal direction Impact Load, thin-wall pipe will produce largely and
The bending ductility deformation of scope, with this impact kinetic energy that dissipates.But, excessive plasticity becomes
Shape can produce flat cross section, makes pipe fitting gradually lose bearing capacity, causes structure to collapse
Collapse.
Summary of the invention
The present invention is to solve above-mentioned deficiency, it is provided that a kind of jacket-type thin-wall pipe
Energy-absorbing auxiliary, reduces thin-wall pipe fasciation under normal direction percussion and cripling.
The above-mentioned purpose of the present invention is realized by following technical scheme: a kind of jacket-type
The energy-absorbing auxiliary of thin-wall pipe, if including dried layer energy-absorbing assembly, every layer of energy-absorbing assembly by
Power-absorbing is constituted, and outermost energy-absorbing assembly is made up of a power-absorbing；Every inside
In the energy-absorbing assembly of a layer, the number of power-absorbing is compared with the energy-absorbing of adjacent outward layer energy-absorbing assembly
Element doubles；Belong to the power-absorbing of same layer energy-absorbing assembly when being two or more,
Interval it is provided with between power-absorbing；It is located relatively at the power-absorbing nesting of outer layer and is bonded in
On two adjacent power-absorbings of internal layer；It is enclosed within suffered by thin-wall pipe outside described energy-absorbing assembly
At impact load.
Described power-absorbing is MULTILAYER COMPOSITE cylinder, for being easy to implement, and desirable and light-wall pipe
The material that part is identical.
Present invention advantage compared with prior art is: the jacket-type thin-walled that the present invention provides
The energy-absorbing auxiliary of pipe fitting, does not affect space and circulation in pipe.By between every layer assembly
Mutually transmission, external impact load in the way of reducing half, shares out equally thin-walled
On pipe fitting, the internal force on thin-wall pipe is made to significantly reduce.Improve unit mass light-wall pipe
The bearing capacity of part and ratio energy-absorbing rate, reduce uniform load property coefficient, decreases local and bends
Bent and destroy, make to be plastically deformed and be evenly distributed on more multi-section.This jacket-type simultaneously
The energy-absorbing auxiliary of thin-wall pipe is reliable and stable, can tackle the normal direction lotus in different parts and orientation
Carry, can be with stable failure mode and regulatable mode by irreversible for external impact kinetic energy
Ground dissipates to be plastically deformed.
