Description
Technical field
This utility model relates to a kind of to a device；Particularly relate to a kind of for pedestrian protection test to a device.
Background technology
Along with the development day by day of automotive safety regulation, the test that automotive crash safety is relevant increasingly comes into one's own.How
By carrying out automotive crash safety test accurately, improve the collision safety performance of automobile, it appears particularly important.The row of automobile
People's protection test is now to require the highest shock safety test.Pedestrian protection test effectively simulates hitting of dummy and automobile
Hit, optimize body structure by shock, reduce automobile with this and pedestrian crashes is injured.At present, pedestrian protection test Europe,
Japan and much his country are all one of mandatory rules of law of must being fulfilled for.So, how pedestrian could be passed through more accurately
Protection test, improves pedestrian protection test result accuracy, for me company car export abroad, satisfied following domestic market
The scoring of regulation and raising NCAP seems the most crucial.
Pedestrian protection test, is to make tentative module with the state of free flight, goes to clash into the testing site preset.In order to make examination
Test module and can strike default testing site, first, looked for for tentative module by the dial gauge being arranged on discharger
Default rum point to test；Secondly, the system input of analysis is preset test rum point, the test parameter such as angle, test speed；
Again, by analysis system, the test shape of exemplar, the position of assay device and gravity factor etc. are compensated calculating；?
After, under the boosting of discharger, tentative module first moves along one section of fixed route, after hit default with free flight state
Testing site.
In above-mentioned pedestrian protection test, dial gauge is to be fixed by floating holder, so fixing dial gauge, can because
The precision of floating holder is the highest, and causes there is range difference between simulating impact point and the default rum point that dial gauge end looks for,
Its range difference can be at about 5mm.The laws and regulations requirement of test, clashing into error in whole process of the test should be within 10mm.And it is right
In point process, default rum point and default rum point the most i.e. have the error of about 5mm so that in bump test, in advance
If the error between rum point and actual rum point can be more than 10mm.Therefore, simulating impact point and default rum point how are reduced
Between error, be a problem demanding prompt solution.
Summary of the invention
