Mathematical Model of a Dummy Cranio-Cervical Complex in Frontal Impact Testing Device

Abstract:

Biomechanics is the science that uses mechanical equations in studying biological structures such as bones, muscles, ligaments, joints and other body structures. It is important in understanding the mechanism of injury to the cervical spine (C1-C7) and head bones. We developed a mathematical approach to mechanical behavior of cervical vertebrae and inter-vertebral discs, in terms of laboratory testing. The paper presents the mathematical model based on Lagrange equations for a frontal impact testing head-neck system. The steps for the solving these equations are exposed in the paper. These studies were combined with FEA and dynamic analysis for determination of constants,parameters, forces and functional relations. Results and conclusions were analyzed in the final of the paper.
