A study on rear seat occupant injuries in side impact
Paper in proceeding, 2012

This paper described a study on the dynamic responses and injury risk of rear seat occupant in side impact. A PSM (Prescribed Structure Motion) model was created based on a passenger car model, which consists of car side structures, a SID-Ils dummy and rear seat in MADYMO environment. The structural responses of the vehicle body were obtained from the FE simulation of side impact. The kinematics of the vehicle body were imported into MADYMO PSM model as loading condition, consequently the kinematic responses of the dummy were acquired from the PSM simulation. It was noticed that the rear seat occupant subjected to a serious head injury, but pelvis force was much smaller than the specified value in C-NCAP (2012). A parametric study was implemented in three impact locations and two impact angles to investigate the risk of head injury. The results show that the head of rear occupant was most likely to be injured in side impact, and the HIC values were large under different form impact In addition, the HIC values of dummy head varied slightly with the different impact positions and angles. Therefore, it is representative that the HIC level of the rear dummy was analyzed through the simulation according to requirement in C-NCAP.
