In the test of multi-angle car-to-car collision, because two cars travel relatively, the success of location and time to test of vehicle joint is particularly important.The deviation calculated, by causing the vehicle head-on collision deviation of position and the deviation of Duplication, more likely causes vehicle miss and security incident occurs, thus causes test failure.Be successfully completed in order to ensure test, and reliable accurate test data can be obtained, be therefore necessary to design a set of vehicle release moment determining device according to the feature of existing draw-off equipment.
Summary of the invention
In view of this, the utility model is intended to propose a kind of to crash test vehicle release moment determining device for vehicle, anticipation can be carried out before the test to cross position and the moment of vehicle, revised by the result of anticipation dispatch a car position and unhook position to vehicle, thus ensure the Pass Test requirement when final shock of two cars, obtain less shock side-play amount.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of vehicle that is used for crashes test vehicle release moment determining device, comprise extension pulley 1, drive the propulsion system of extension pulley 1, uncoupling rigging 7, power supply 2, aerosol producer 3, scotch 4 and trigger switch 5, described extension pulley 1 is 2, be separately positioned on corresponding traction track 8, described each extension pulley 1 is all connected with propulsion system, described each extension pulley 1 is all arranged power supply 2 and aerosol producer 3, described each extension pulley 1 front end all arranges trigger switch 5, described trigger switch 5 one end is electrically connected with power supply 2, the other end is electrically connected with aerosol producer 3, described every bar traction track 8 is equipped with successively the uncoupling rigging 7 and scotch 4 that disconnect for extension pulley 1 and propulsion system along extension pulley 1 travel direction, also comprise and act on the high-speed camera 6 of image for gathering aerosol producer 3 on two extension pulleys 1.
Further, described aerosol producer 3 is arranged on extension pulley 1 front portion.
Further, described extension pulley 1 is connected with propulsion system by cable wire.
Further, the distance between described uncoupling rigging 7 and scotch 4 is 10-20mm.
Further, described high-speed camera 6 is arranged on the side of traction track 8, described high-speed camera 6 and two equidistant settings of scotch 4.
Relative to prior art, one described in the utility model be used for vehicle crash test vehicle release moment determining device there is following advantage:
One described in the utility model be used for vehicle crash test vehicle release moment determining device, by analyzing the image caught, obtain two extension pulley collision times poor, and the position of dispatching a car needing to revise is calculated according to test speed, two head-on collision vehicles can be made to clash in the position of estimating and moment, thus obtain less shock side-play amount.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 for the one described in the utility model embodiment for vehicle crash test vehicle release moment determining device structural representation.
Description of reference numerals:
1-extension pulley, 2-power supply, 3-aerosol producer, 4-scotch, 5-trigger switch, 6-high-speed camera, 7-uncoupling rigging, 8-traction track.
Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Figure 1, a kind of vehicle that is used for crashes test vehicle release moment determining device, comprise extension pulley 1, drive the propulsion system (not shown) of extension pulley 1, uncoupling rigging 7, power supply 2, aerosol producer 3, scotch 4 and trigger switch 5, described extension pulley 1 is 2, be separately positioned on corresponding traction track 8, described each extension pulley 1 is all connected with propulsion system by cable wire (not shown), described each extension pulley 1 is all arranged power supply 2 and aerosol producer 3, it is anterior that aerosol producer 3 is arranged on extension pulley 1, described each extension pulley 1 front end all arranges trigger switch 5, described trigger switch 5 one end is electrically connected with power supply 2, the other end is electrically connected with aerosol producer 3, described every bar traction track 8 is equipped with successively the uncoupling rigging 7 and scotch 4 that disconnect for extension pulley 1 and propulsion system along extension pulley 1 travel direction, also comprise and act on the high-speed camera 6 of image for gathering aerosol producer 3 on two extension pulleys 1, described high-speed camera 6 is arranged on the side of traction track 8, equidistant setting between high-speed camera 6 and two scotch 4.
When car is to car multi-angle impact test, vehicle is connected by extension pulley with haulage cable and obtains and travels tractive force.Arrive before collision prediction place at vehicle, first extension pulley departs from haulage cable, and afterwards, extension pulley and testing vehicle depart from and clash into the coaster scotch fixed in orbit and stop, and are gone out by vehicle emissions.Extension pulley and vehicle disengaged position can reflect whether extension pulley and testing vehicle run according to the parameter preset.
Before car is to the official test of car multi-angle impact test, this device is utilized to carry out pretest.First, power supply 2, aerosol producer 3 and trigger switch 5 are arranged on the extension pulley 1 of corresponding traction track 8, secondly, the reference position of extension pulley 1 is systemic presupposition position, scotch 4 is positioned over the 20mm place after uncoupling rigging 7 position simultaneously, then, speed according to testing requirements is tested, two extension pulleys 1 are when contacting with respective scotch 4, power supply 1, the loop that aerosol producer 3 and trigger switch 5 are formed forms path, aerosol producer 3 is had an effect, to emerge white smoke, now, gather aerosol producer 3 on two extension pulleys 1 by high-speed camera 6 and act on image, the mistiming that two extension pulleys 1 arrive assigned address is obtained by image, high-speed camera 6 number of pictures per second is 1000 frames, can judge that two extension pulleys 1 arrive the millisecond number of assigned address phase difference by high-speed image, finally, can be revised the reference position of extension pulley 1 by mistiming and test speed, thus reach the target that vehicle arrives appointment position of collision simultaneously.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
