Owing to the size in the second induction hole 111, induction hole 112 first is long, on the first absorption cell 11, plane is at the first induction hole 111
Defect is induced at hole 112 than more than second, causes the deformation of the first absorption cell 11 first to fold at the second induction hole 112
Deformation, offers generation folded deformation on position in the second induction hole 112 the most successively, and last Folding Deformation occurs first
On the position in induction hole 111.
The endergonic structure that the present invention provides utilizes the multiple induction holes arranged, and controls the first absorption cell 11 and the second absorption cell
The deformation pattern of 21, reduces the feature of impact force；Make energy absorption device have the second absorption cell 21 to occur from front to back to fold to become
Shape, there is folded deformation in the first absorption cell 11, during the energy-absorbing of the energy absorption device second level, dynamic force is steady from back to front.
It addition, the energy absorption device of the present invention is for body construction, there is independent function and version, permissible
Parts as track vehicle body structure carry out separately machined manufacture；Bedplate 3 provides group for whole energy absorption device
Attaching mouth, can assemble mode with bedplate 3 by bolt or welding etc., be assembled on the drivers' cab front wall 4 of body construction, when
When collision accident occurs, under impact load effect, first it is the compression controlled by energy absorption device order of occurrence, absorbs
Kinetic energy in collision, protection body construction will not occur serious structural plasticity to deform, when energy-absorbing dress compression completes, body construction
Part plastic deformation only can occur, and other structural regions are elastic deformation；Therefore, in collision process, energy absorption device has
Imitate protects body construction；After collision accident, fill by the energy-absorbing having occurred plastic deformation to lose function can be dismantled
Put, the energy absorption device more renewed, carry out rapid-maintenance vehicle.
Relative to the endergonic structure of prior art, the energy absorption device that the present invention provides has the advantage that
(1) energy absorption device of the present invention has the energy absorption ability of 0.8MJ, improves the impact resistant performance that improve CRH3；When
When train crashes, first it is mounted to the energy absorption device generation collapse-fold formula plastic deformation of drivers' cab front wall 4, inhales
Receive the kinetic energy in collision, effectively protect body construction.
(2) the energy absorption device version of the present invention is simple, manufacture processing simple, it is only necessary at day font extrudate
Top and bottom are offered and are suitably induced pore structure, by the first cover plate 12 arranged and the second cover plate 22 and mounting seat welding group
Dress, greatly reduces energy absorption device cost.
(3) replacing of energy absorption device is simply easy in installation, is effectively increased the practicality of this energy absorption device, beneficially market
Popularization and application.
Last it is noted that various embodiments above is only in order to illustrate technical scheme, it is not intended to limit；To the greatest extent
The present invention has been described in detail by pipe with reference to foregoing embodiments, it will be understood by those within the art that: it depends on
So the technical scheme described in foregoing embodiments can be modified, or the most some or all of technical characteristic is entered
Row equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from various embodiments of the present invention technology
The scope of scheme.
