Abstract

This study presents rear-end collision simulations and analyses under various impact conditions by employing a validated biofidelic multi-body (MB) model of the whole human spine and a finite element (FE) model of the C2-C3 disc segment. FE model is used in conjunction with the MB model where predictions of the multi-body model under dynamic impact loading conditions are utilised as boundary conditions for the finite element model of the disc. The models successfully reproduce the characteristic motion of the head and neck when subjected to rear end crash scenarios. Head translations and rotations, maximum intervertebral angles in extension, and intervertebral disc forces and stresses are presented.
