Abstract
The paper presents the studies made on a similar biomechanical system composed by neck, head and thorax bones. The models were defined in a CAD environment which includes Adams algorithm for dynamic simulations. The virtual models were obtained starting with tomographic images made on a living human subject. The main movement analyzed were: axial rotation (left-right), lateral bending (left-right) and flexion-extension movement. After simulation was obtained the entire mechanical behavior based on data tables or diagrams. That virtual model composed by neck and head can be included in complex system (as a car system) and supposed to impact simulations (virtual crash tests).
