Experiment on Function is missed for the side curb that speed is 10Km/h and carries out real vehicle impact test, and intuitively acquisition is true, has
The data of effect are coincide very much with actual conditions, and compared with software is simulated, data precision is greatly improved.By using
Truly, effective data, it can well analyze and solve to work as vehicle in the case where turning the corner at full speed, a side impaction of vehicle
To curb, the problem of making to lead airbag-releasing, or even injure the generation of occupant's accident.Meanwhile the present invention can be by more convenient
Ground, accurately adjust three straight longerons 16 and collide the upper-lower position between wall 3 and more easily, accurately adjust whole firm
Property obstacle and collision wall 3 between upper-lower position, with adapt to the test vehicle side collision of different-diameter tire experiment collision
Need.
As shown in Figure 1, the entablature 14, sill 15 and spandrel girder 12 are the frame body of mesh font.This causes
Crossbeam 14, sill 15 and spandrel girder 12 it is relatively simple for structure, manufacture is easier and rigidity is higher.
As shown in Figure 2, the entablature 14 can be the frame body of day font.In fact, the entablature 14, sill
15 and spandrel girder 12 can also be day font frame body.This causes the structure of entablature 14, sill 15 and spandrel girder 12
Simpler, manufacture is easier and rigidity also disclosure satisfy that and use needs.
From the figure 3, it may be seen that the entablature 14 can also be the frame body of matrix pattern.In fact, the entablature 14, lower horizontal stroke
Beam 15 and spandrel girder 12 can also be the frame body of matrix pattern.This is again such that entablature 14, sill 15 and spandrel girder 12
Structure it is simpler, manufacture is easier and rigidity also disclosure satisfy that using needs.
The entablature 14, the width of sill 15 and spandrel girder 12 from front to back respectively not less than 30cm, 50cm and
The height of straight longeron 16 and oblique longeron 17 is no more than 100cm described in 120cm.Can either so ensure Inclination body 1 itself is firm
Degree, caused energy in experiment can be born and indeformable, raising service life, additionally it is possible to easily adjust whole rigid obstacle
Height, preferably meet experiment in different height test vehicle 5 experiment needs.Simultaneously, additionally it is possible to facilitate fork truck, driving etc.
Respectively to the carrying of entablature 14, sill 15 and spandrel girder 12.
As shown in Figure 5, each tiltedly oblique angle A between longeron 17 and entablature 14, sill 15 and spandrel girder 12
Angle is more than 45 °.It so can effectively prevent that test vehicle is turned on one's side in experiment collision, avoids unnecessary damage, and make
Test vehicle Reusability as far as possible, reduce experimentation cost.
As shown in Figure 1, present invention additionally comprises the mounting fixing parts 13 with the pairing connection of straight longeron 16, the straight longeron 16 are logical
Corresponding mounting fixing parts 13 are crossed to be connected with can adjust upper-lower position with collision wall 3.This make it that straight longeron 16 and collision wall 3 are adjustable
Connect whole upper-lower position it is relatively simple for structure, and adjust upper-lower position also it is more convenient easily.So as to make whole rigid walls
It is also fairly simple to hinder the structure being connected with can adjust upper-lower position with collision wall 3, and upper-lower position is also more convenient easy.
As shown in Figure 1, the mounting fixing parts 13 are the elongated plate suitable with the height of straight longeron 16, itself and straight longeron
16 connect and are stretched out by the side of straight longeron 16, and arranged with being from top to bottom provided with spacing on the part to stretch out
Longitudinal waist-shaped hole 130, the straight longeron 16 is by longitudinal waist-shaped hole 130 on fixture 13, using bolt（It is not drawn into, similarly hereinafter）
It is connected with can adjust upper-lower position with collision wall 3.This causes the knot that straight longeron 16 is connected in which can adjust upper-lower position with colliding wall 3
Structure is simpler, and it is more convenient easy to adjust upper-lower position.So as to make whole rigid obstacle adjustable up and down with collision wall 3
The structure connected to position is simpler, and it is more convenient easy to adjust upper-lower position.
As shown in Figure 1, it is provided with lambdoid tie-beam 19 in the spandrel girder 12.This causes the bearing capacity of spandrel girder 12
Higher, service life is also higher.
As shown in Figure 1, present invention additionally comprises two bolt groups 6, it is equipped with described two curbs 2 from its rear end to both sides
The installation portion 20 of extension, the installation portion 20 are provided with by the upper supreme installation screw each other away from ground arrangement（It is not drawn into, under
Together）, the spandrel girder 12, which is provided with, coordinates installation screw（It is not drawn into, similarly hereinafter）, described two curbs 2 are by installation screw and match somebody with somebody
Installation screw is closed, the left and right ends that one group of installation bolt group 6 is connected to the front end of spandrel girder 12 are respectively adopted.This causes two roads
The renewal of shoulder 2 is replaced more convenient easy.
The present invention is as follows using process；
Referring to Fig. 1 and Fig. 6, whole rigid obstacle is connected on collision wall 3 first, and according to different tire size
Vehicle is tested, adjusts the position upper up and down between whole rigid obstacle and collision wall 3, the height being allowed to required for Pass Test.
Then, whole rigid obstacle is fixedly connected with collision wall 3.Afterwards, ready test vehicle 5 is placed into experiment and used and flown
On row carpet device 4, and make the vehicle body longitudinal centre line of test vehicle 5 vertical with collision course, finally with 10Km/H speed
Tested.
