Abstract
The invention relates to a real vehicle crash testing method, which comprises the following steps that firstly, a front towing vehicle is hung at the front end of a testing vehicle through two front towing hanging chains, a back towing vehicle is hung at the back end of the testing vehicle through two back towing hanging chains, then, a towing motive power mechanism is connected with the front towing vehicle through a towing rope so that the front towing hanging chains and the back towing hanging chains are tightened, next, the front towing vehicle drives the testing vehicle and the back towing vehicle to simultaneously move toward the collision counterguard direction through the driving of the towing motive power mechanism, the testing vehicle firstly moves to the release position of the front towing vehicle, the front towing vehicle is released, the testing vehicle moves to the release position of the back towing vehicle, the back towing vehicle is released, then, the testing vehicle freely slides to impact the collision counterguard, and cameras shoot deformation videos in the collision process. The method has the advantage that the smaller collision offset quantity is maintained on the premise of ensuring the image pickup effect.
Description
Technical field
The present invention relates to a kind of safety test method of vehicle, relate to specifically a kind of real vehicle collision test method.
Background technology
In real vehicle collision test, test vehicle is drawn to certain speed by the front haulage car by trailer system, bumps with obstacle afterwards, thereby finishes test.Exert an influence for fear of the collision of trailer system to test vehicle, at vehicle with before obstacle contacts, trailer system can be thrown off and being connected of test vehicle, make vehicle be in the art skating state, high-speed camera is laid in a lot of testing requirementss below collision area, with the deformation of vehicle bottom in the record process of the test.For guaranteeing good photographic effect, guarantee that vehicle bottom is not pulled car and blocks, usually at collision 3-5 rice, obstacle the place ahead, tractor is thrown off with test vehicle to be connected, this just means that test vehicle has the art skating distance of 3-5 rice, and in this segment distance, test vehicle is not subjected to the restriction of tractor, if the four-wheel location is not accurate enough, then can produce horizontal deviation.Yet in impact test, there is relatively strict requirement the position of Vehicular impact obstacle, particularly in positive 40% impact test, side-play amount must not be above 20 millimeters.The traction method that adopt present domestic real vehicle collision test chamber is single tractor front end traction, and in order to satisfy the less requirement of collision side-play amount, instruction carriage art skating distance is shorter.But for the high-speed camera of bottom, art skating short meaning in the video that records of distance, tractor can block the test vehicle bottom, affects shooting effect, does not reach the purpose of complete seizure vehicle bottom distortion.If obtain complete deformation of bottom video, just need to increase the art skating distance, and this can make the collision side-play amount increase, even can surpass the ultimate value of testing requirements, cause test failure.
Summary of the invention
The purpose of this invention is to provide a kind of real vehicle collision test method, it can under the prerequisite that guarantees photographic effect, keep less collision side-play amount.
To achieve these goals, technical solution of the present invention is: a kind of real vehicle collision test method, may further comprise the steps: 1) make the front haulage car hang over the test vehicle front end by two front haulage chainings, the rear haulage car hangs over the test vehicle rear end by two rear haulage chainings, article two, the front haulage chaining is vertically symmetrical with respect to the vehicle body of test vehicle, article two, the rear haulage chaining is vertically symmetrical with respect to the vehicle body of test vehicle, make again traction power mechanism connect the front haulage car by traction rope, 2) make the front haulage chaining, the rear haulage chaining is tightened, 3) under the drive of traction power mechanism, make front haulage car motoring ring test vehicle, in the same way impact walls barrier direction motion of rear haulage car one, move to first front haulage car off-position, the front haulage car is discharged, move to again rear haulage car off-position, the rear haulage car is discharged, then the test vehicle art skating hits the collision obstacle, and video camera takes anamorphic video in the collision process.
Real vehicle collision test method of the present invention, wherein, the front end of described rear haulage car is fixed with energy-absorbing material.
Real vehicle collision test method of the present invention, wherein, described energy-absorbing material is the honeycomb aluminium block.
Real vehicle collision test method of the present invention, wherein, described traction power mechanism is motor, described traction rope is wire rope.
After adopting such scheme, real vehicle collision test method of the present invention is because the test vehicle rear end hangs with the rear haulage car, and the front haulage car discharges prior to the rear haulage car, in the situation that the front haulage car makes things convenient for video camera to take, guarantee photographic effect after discharging, the rear haulage car plays the effect of limit assay vehicle rear wheel transverse shifting, reduces the collision side-play amount of test vehicle.
In addition, because rear haulage car front end is fixed with energy-absorbing material, prevent from damaging because colliding with the front haulage car after the rear haulage car from discharging.
Description of drawings
Fig. 1 is the schematic diagram of real vehicle collision test method of the present invention.
Embodiment
As shown in Figure 1, real vehicle collision test method of the present invention may further comprise the steps:
1) make front haulage car 01 hang over the front end of test vehicle 02 by two front haulage chainings 11, rear haulage car 03 hangs over the rear end of test vehicle 02 by two rear haulage chainings 31, before, rear haulage chaining 11,31 be connected to test vehicle 02 before, on the rear suspension, and two front haulage chaining 11 is vertically symmetrical with respect to the vehicle body of test vehicle 02, article two, rear haulage chaining 31 is vertically symmetrical with respect to the vehicle body of test vehicle 02, make traction power mechanism connect front haulage car 01 by haulage cable, the front end of rear haulage car 03 is fixed with energy-absorbing material 32, energy-absorbing material 32 can be selected the honeycomb aluminum piece
2) front haulage chaining 11, rear haulage chaining 31 are tightened,
3) under the drive of traction power mechanism, the in the same way impact walls barrier direction motion of front haulage car 01 motoring ring test vehicle 02, rear haulage car 03 1, move to first front haulage car off-position, front haulage car 01 is discharged, move to rear haulage car off-position again, rear haulage car 03 is discharged, then test vehicle 02 art skating hits the collision obstacle, video camera takes anamorphic video in the collision process, the optional motor of using of above-mentioned traction power mechanism.
The above embodiment is described preferred implementation of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that the common engineering technical personnel in this area make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
