Description
Technical field
The utility model belongs to guideway vehicle passive security technical field, relates to the passive safety feature of train head.
Background technology
Energy absorption device is the important component part of train passive security technical field, raising train passive security performance plays irreplaceable effect, its groundwork is generally install power-absorbing at car end, irreversible plastic deformation occurs or destroys to absorb collision energy by power-absorbing in collision process, the deformation pattern that dissimilar power-absorbing adopts is general also different.Current widely used collapsible (or claiming crushing type) energy absorption device is that the folding plastic deformation by making structure be similar to " accordion " formula in collision process absorbs collision energy, reaches the object reducing car body deformation extent and protection passenger inside the vehicle safety.Chinese Patent Application No. 201110424043.9 discloses in Tangshan passenger vehicle Company Limited by Shares patent of invention " troubleshooting energy absorption device and motor train unit head car " and relates to a kind of pilot with energy-absorbing, in troubleshooting beam rear end, energy absorbing tube and energy-absorbing bearing are installed, in collision process, energy absorbing tube is through bearing generation crimp, reaches endergonic object.
Common are following several at present: one, based on the collapsible energy absorption device of folded deformation, the energy absorption device such as conquassation pipe, energy-absorption box conventional is at present all based on this deformation pattern.Bend plastic deformation to absorb collision energy mainly through structure in collision process.Due to the previous stage bent, bending stiffness is larger, so resistance increases gradually along with compression process, when being deformed to a certain degree, tube wall there occurs plastic bending (deformation process is similar to the unstability of Euler flexing a bit), resistance is caused sharply to decline, after reaching stabilized conditions, other positions of tube wall continue to produce flexural deformation, then unstability, and so forth, make the resistance fluctuation of pressing-crack energy absorption device in endergonic process comparatively large, this is disadvantageous to the safety of passenger.
Two, based on the energy absorbent block of honeycomb structure conquassation, refer in collision process by honeycomb structure progressively conquassation absorb collision energy, although this kind of structure resistance is comparatively mild, there is absorbing energy capacity little, the defects such as design absorbing energy capacity is wayward.
Three, based on the energy absorbing tube of turnup distortion, the distortion of continuous turnup inwardly or is outwards there is and absorbs collision energy in this energy absorption device mainly through pipe, the resistance in its later stage is comparatively mild, but phase when distortion (namely trigger) there will be a larger peak value before being deformed, and this peak value also can cause harmful effect to passenger safety.
According to l-G simulation test, because flexing unstability distinctive in collapsible energy absorption device deformation process can cause the resistance passing to car body to have larger fluctuation, this is disadvantageous to the personal safety of passenger.In view of the above deficiency that prior art exists, devise a kind of energy absorption device based on " crimp " and be necessary.
Utility model content
The purpose of this utility model is to provide a kind of squash type energy absorption device, and it can solve resistance when train is collided effectively the problem of larger fluctuation.
The purpose of this utility model is achieved through the following technical solutions: a kind of squash type energy absorption device, comprise the energy absorbing tube fixed vertical with adapter plate, adapter plate is provided with upper and lower two row's circular mounting hole, energy absorbing tube is the pipe with uniform wall thickness, one end of pipe is variable diameters open end, and the other end is equal diameter closed end; The open end of energy absorbing tube is fixed by butt flange is vertical with adapter plate; The external diameter of butt flange is provided with step, and internal diameter is diameter bore, the open end external diameter interference fit of this diameter bore and energy absorbing tube, and one end of butt flange embeds mounting hole, and described step end face and adapter plate are by being welded and fixed.
Described adapter plate is provided with two, lower four liang of row's circular mounting hole.
Described adapter plate is provided with bolt hole.
Wherein, described butt flange is circular flange.The inner diameter bore of described butt flange and energy absorbing tube open end external diameter coincide, and be dimensioned slightly smaller than energy absorbing tube open end external diameter, described energy absorbing tube open end is embedded diameter bore and is fixed on butt flange by interference fit.
Squash type energy absorption device described above, wherein, described adapter plate has circular mounting hole, and described butt flange is embedded mounting hole and fixed on a mounting board by welding manner.Described adapter plate has bolt hole, by bolt, whole energy absorption device is connected on car body.
In collision process, through the diameter bore of butt flange, there is crimp to absorb collision energy under becoming the induction of inner diameter through-hole at butt flange in energy absorbing tube under the promotion of impact.This kind of energy absorption device has resistance and changes mild advantage, compensate for the deficiency existing for traditional collapsible energy absorption device, can protect the safety of driver and passenger inside the vehicle better.
The utility model effect compared with prior art and advantage are: described squash type energy absorption device is mild in the change of collision process middle impedance power, peak value is little, without big ups and downs, and resistance, energy-absorbing stroke are directly related with energy absorbing tube geometric parameter, and absorbing energy capacity design is convenient.It is a kind of more satisfactory energy-absorbing modes.
