Head concussion and neck injury are often induced by an accident even in a minor collision. In this study, a discrete model of masses, springs, and dampers are considered which represent the components of a vehicle-passenger system. The vehicle accounts for 5 degrees of freedom (DOF) whereas the passenger contributes an additional 5 DOF. Differential equations that express the dynamic forces and moments acting upon each mass are developed and then solved numerically using Runge-Kutta method. The results were used to validate the use of such a model to accurately represent real life crash situations. The primary responses of the model are the magnitudes of acceleration experienced by various sections of the model and their relative displacements in two-dimensional space. Analyses were conducted at varying crash velocities and also with different model configurations. It was found that the behavior of the model corresponds well to previous studies and also to what one would intuitively expect at actual collision scene.
