abstract="In 2008, fatalities resulting from vehicle rollover events accounted for over one third of all fatalities resulting from motor vehicle crashes. This study describes the initial phase of a detailed computational study aimed at developing causal relationships between crash, occupant, and vehicle parameters and injury outcome using state-of-the-art computational methods. This initial phase examines the sensitivity of vehicle kinematics and structural deformation by isolating the roof-to-ground interaction phase of the rollover event using an LS-DYNA finite element full-vehicle model. Structural deformation is quantified by a measure of the maximum roof intrusion into the occupant space (average = 44 cm, range = 9?66 cm). Roll angle, pitch angle and drop height have a significant effect on structural deformation, while roll rate and yaw angle do not show significant effects. Drop height alone accounts for 70% of the variability in peak roof crush and vertical acceleration, metrics that are related to causal mechanisms for injury.<p />",
