Abstract

This paper proposes a 2D dynamical model for evaluating parameters affecting whiplash. In fact a four segment dynamical model is developed in the sagittal plane for the analysis. The model response is validated using the existing experimental data and is shown to simulate the "S-Shape" and "initial upward ramping" kinematics of the cervical spine and the resulting dynamics observed in human and cadaver experiments. The model is then used to evaluate the effects of parameters such as velocity change between rear vehicle and the target vehicle (), head/head restraint separation (backset) and the awareness of occupant on the whiplash injuries. It is shown that the proposed model can simulate whiplash phenomena very well; therefore it is a suitable alternative for other existing models.
