Development of a modelization of human being in lateral impact, to mitigate the insufficiencies of actual side i mpact dummies

In previous publications, the biofidelity of EUROSID and SID dummies was evaluated in lateral impacts, according to ISO human reference data. The main conclusions of these evaluations was that both dummies display a rather poor biofidelity, and so they are inappropriate for use to improve lateral protection of occupants. More, their conception is very different from that of human beings and it is shown in particular that the first five ribs of the 50th percentile human being do not have any equivalent on both dummies; the mechanical characteristics of the thorax and abdomen have no similarity with those of the corresponding body areas in the human being. For these reasons it is necessary to have recourse directly to the human beings.

After performing special tests with human subjects, in order to obtain the necessary data which do not exist in bibliography, a modelization of the human being was developed by the LPB-APR, to be integrated in the CCMC.CTP. The validation of this model was checked out by using results of biomechanical tests with human subjects, selected as being the best available references. These data were then integrated for the human representation in the CTP and the first results obtained are promising.
