Abstract
Modelling of human cervical spine and numerical simulations of dynamical internal forces in a situation corresponding to real car accident are presented in this paper. The human body behaviour, especially the head movement, have a significant influence on type and scale of spine injuries. In order to analyse correlation between head movement and physical phenomena in neck two dynamical non-linear models were created. The first two-dimensional model was created using professional system WorkingModel 2D and the second spatial model (as an author program) formed in MatLab system. Results of numerical simulations allowed to quantitatively estimate the most dangerous for passengers position of the head.
