Abstract
A planar mathematical brain injury model was analyzed to find various system characteristics. The damped and undamped natural frequency was approximated by assuming the system behaves as a second order equation. Symmetry was found between the angle of impact superior and inferior to the transverse plane for maximum relative brain motion. A sensitivity analysis was preformed for various head impact scenarios and input locations. The model was found to be most sensitive to the brain moment of inertia followed by the brain mass and insensitive to the selected spring constants and damping coefficients for all impact scenarios.
