Abstract

A 3D model of the thorax including shoulders and abdomen was developed. The model was designed to predict human responses and kinematics under all crash conditions (frontal, oblique and lateral). The geometry chosen is that of the 50th percentile adult male in a seated posture. The anatomy is represented by 6000 spring, shell, membrane and brick elements. 22 validation test configurations were carefully selected and 50 validation corridors were established. There is good agreement between model results and experimental data so the model is already in use for several applications such as the development of cadaver experiment protocols.
