Simulation Analysis of the Rear Seat Female in Front Impact

The 2012 C-NCAP added the evaluation of the potential risks of injury of female occupant in the rear seats. A female dummy will be used in the C-NCAP test. The frontal impact model of the female dummy in the rear seats was established by MADYMO. Four different vehicles were analyzed respectively in the two conditions that whether the secondary crash occurred or not. And the effect of the three factors which included the vehicle acceleration, rear space and seatbelt on the female dummy injury was summarized. Experimental results showed that with the peak acceleration smaller and the rebound time later, the values of dummy injury on the head and neck would be smaller under the premise of the same vehicle, and appropriate seat belts load limiter could reduce the dummy injury.
