Big Data Analysis and Calculation on Occupant Protection Based on Intelligent Sled Test System in Passenger Car

GB 11552-2009 is one of the important standards for testing the interior fittings of the passenger car, while its judgment method is only to verify whether the dummy’s head is in contact with the instrument panel, and other parts of the dummy are not examined. In order to further improve the GB 11552 and better protect the occupants, dummy injury of 60 tests for 20 vehicle models is studied and analyzed based on the sled test method in this paper. Test results show that the occupant’s head, trunk and lower limbs are damaged to different degrees. Therefore, it is suggested that the injury of the dummy other parts should be taken into account in the later revision of GB 11552.
