Induction hole 111 and second induces hole 112 to be provided with certain size and installation position, causes to induce hole 111 and the according to first
Two induction 112 structure sizes of hole, position effectively to control deformation sequence and the fold position of the first absorption cell 11；Specifically,
Since the second induction hole 112 first induces the size in hole 111 long, plane is at the first induction hole 111 on the first absorption cell 11
Defect ratio is more than at the second induction hole 112, and the deformation of the first absorption cell 11 is caused to be folded from the second induction hole 112 first
Then deformation opens up successively in the second induction hole 112 and folded deformation occurs on position, the last one Folding Deformation is happened at first
On the position for inducing hole 111.
Endergonic structure provided by the invention controls the first absorption cell 11 and the second absorption cell using multiple induction holes of setting
The characteristics of 21 deformation pattern, reduction impact force；So that there is energy absorption device the second absorption cell 21 to occur to fold change from front to back
Folded deformation occurs from back to front for shape, the first absorption cell 11, and dynamic force is steady when the energy-absorbing of the energy absorption device second level.
In addition, the energy absorption device of the present invention for body construction, has independent function and structure form, it can be with
A component as track vehicle body structure carries out separately machined manufacture；Base board 3 provides group for entire energy absorption device
Attaching mouth can be assembled in base board 3 by assembly methods such as bolts or welding on the drivers' cab front wall 4 of body construction, when
Under impact load effect, absorbed by the controllable compressive deformation of energy absorption device order of occurrence first when collision accident occurs
Kinetic energy in collision, serious structural plasticity deformation will not occur for protection body construction, when energy-absorbing dress compression is completed, body construction
Part plastic deformation can only occur, other structures region is flexible deformation；Therefore, in collision process, energy absorption device has
Effect protects body construction；After collision accident, by the way that the energy-absorbing dress that plastic deformation has occurred and has lost function can be dismantled
It sets, the energy absorption device more renewed, carries out rapid-maintenance vehicle.
Endergonic structure compared with the existing technology, energy absorption device provided by the invention have the following advantages：
(1) energy absorption device of the invention has the energy absorption ability of 0.8MJ, improves the crash worthiness energy for improving CRH3；When
When train crashes, collapse-fold formula plastic deformation occurs for the energy absorption device for being mounted to drivers' cab front wall 4 first, inhales
Receive the kinetic energy in collision, effective protection body construction.
(2) energy absorption device structure type of the invention is simple, and manufacture processing is simple, it is only necessary in stud extrudate
Top and bottom open up suitable induction pore structure, pass through the first cover board 12 of setting and the second cover board 22 and mounting seat welding group
Dress greatly reduces energy absorption device cost.
(3) replacement of energy absorption device is simply convenient in installation, effectively increases the practicability of the energy absorption device, is conducive to market
Popularization and application.
Finally it should be noted that：The above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Present invention has been described in detail with reference to the aforementioned embodiments for pipe, it will be understood by those of ordinary skill in the art that：Its according to
So can with technical scheme described in the above embodiments is modified, either to which part or all technical features into
Row equivalent replacement；And these modifications or replacements, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
The range of scheme.
