Description

Automobile RCAR and front and back end low speed collision experimental rig

Technical field

Vehicle performance testing equipment field is the utility model is related to, especially a kind of automobile RCAR and front and back end low speed collision Experimental rig.

Background technology

With the improvement of living standards, requirement of the people for the security performance of vehicle is also higher and higher.In life, vapour Often there is a situation where low speed front end crash, rear impact collision etc. in city for car.Insurance can be produced after vehicle low speed collision Situations such as damage of the correlated parts such as thick stick, collision prevention girders and lamps and lanterns, this can be related to the vehicle maintenance after accident and part replacement, So as to produce maintenance cost.According to regulation now, which is often undertaken by insurance company.Therefore either consumer Or insurance company is required to the performances such as the damage resistance of the performance to automobile in low speed collision, maintenanceability and carries out certain wind Danger assessment, based on the above situation, in the design and production of automobile, each automobile production manufacturer and laboratory are both needed to carry out automobile Impact test.

Mainly there are European Union RCAR (Research on the evaluation method of vehicle low speed collision damage resistance and maintenanceability at present Council for Automobile Repairs) low speed collision code, China GB17354《Automobile front and back end protective device》With And front and back end low speed collision is tested as defined in Europe superscript ECER42 and American Standard FMVSS Part 581Bumper Standard.

The automobile industry of China is developing rapidly, and more and more automobile industries have walked out the gateway of a country, and therefore, Chinese automobile exists Design is tested with often carrying out the low speed collision of multiple standards during production.

In four kinds of above-mentioned codes, European Union RCAR low speed rear impacts testing regulations regulation, the driver of test vehicle Place the dummy of a predetermined weight for side, and the mobile obstacle of rigidity is collided with certain quality, impact velocity, certain collision angle Onto the defined point of impingement of test vehicle afterbody, wherein the road clearance for moving obstacle lower end is 200mm.The experiment can also By first impinger for being fixed with the test determination (to distinguish Chinese GB17354 and American Standard FMVSS Part 581 In impinger) pendulum carry out the equivalent quality and height for replacing mobile armband, but needing accurate control pendulum, to reach and move The consistent collision effect of swing arm chapter.

Chinese GB17354《Automobile front and back end protective device》It is completely the same with Europe superscript ECER42, in above-mentioned standard, when into A front and back end, longitudinal direction and car corner impact drive a vehicle when testing, it is necessary to collision test device by the second impinger as defined in the standard (to distinguish the impinger in the impinger in Europe superscript RCAR and American Standard FMVSS Part 581) is fixed on pendulum and with one Fixed quality, impact velocity, certain collision angle are collided as defined in instruction carriage on the point of impingement, wherein China GB17354 with The terrain clearance of the datum line of the impinger of Europe superscript ECER42 is 445mm, and lower end terrain clearance is 140mm, in addition, in China In GB17354 and Europe superscript ECER42, impact velocity is also different with European Union RCAR low speed rear impact testing regulations.

American Standard FMVSS Part 581Bumper Standard and the regulation of China GB17354 are essentially identical, its difference It is in the 3rd impinger as defined in the standard is different from the shape of the second impinger of China GB17354, is touched compared to second Device is hit, the 3rd impinger needs to increase an additional facet on the second impinger.But the liftoff height of the datum line of the 3rd impinger The terrain clearance of degree and lower end is identical with the defined regulation of Chinese GB17354.

In impact test, it is necessary first to the height of pendulum is adjusted, the terrain clearance of impinger is met the needs of experiment, Then device is drawn high by pendulum again and pendulum is pulled up to certain altitude, at the time of making pendulum with test vehicle collision, pendulum Speed disclosure satisfy that the needs of experiment, and test vehicle then is positioned over specific position according to the needs of experiment, is finally discharged Pendulum, hits vehicle by pendulum, then draws the performances such as damage resistance, the maintenanceability of performance of the automobile in low speed collision. In collision, in order to the precision of guarantee test, it is also necessary to hit the speed of instantaneous vehicle to pendulum by pendulum velocity measurement mechanisms Degree measures.Pendulum secondary collision is influenced caused by experiment in order to prevent, it is also necessary to by pendulum arrestment mechanism to hitting Pendulum after automobile is braked.But in test, the terrain clearance to pendulum, pendulum draw high height and pendulum tachometer Relative position between structure, pendulum arrestment mechanism and pendulum, there is very high required precision.

The standard of above-mentioned three types can be as the performance to automobile in low speed collision damage resistance, maintenanceability Assessed etc. performance, but in test, the shape of each impinger, the terrain clearance of pendulum, the height of pendulum velocity measurement mechanisms, pendulum The height that the height and pendulum of hammer arrestment mechanism are drawn high differs.Since the complicated of collision test device, entirety are larger, The debugging of parts is highly difficult in equipment, and the precision of test requirements document is very high, therefore in the prior art, go back neither one collision examination Experiment device while guarantee test efficiency and test accuracy, can at the same time be suitable for the examination of above-mentioned three types standard Test.
