The aim of this work is to study the influence of head boundary conditions during real-world pedestrian head trauma simulation. Both Multi-Body System (MBS) and Finite Element (FE) models are used for pedestrian-versus-vehicle accident reconstructions. Four head boundary conditions are studied (from an isolated head to a head attached to the whole body). The effect of each configuration on head mechanical response parameters is computed. The responses include rigid-body kinematics responses as well as the intra-cerebral responses of a head FE model. It appears that head boundary conditions at neck level are significant, especially in terms of intra-cerebral response.
