Rollover collisions are very complex and the subject of significant interest. Roll-over collisions involving Sport Utility Vehicles (SUV) are of particular interest due to their high center of gravity (increased propensity for rollover) and recent surge in popularity. The following research examines SUV rollover collisions documented in the National Automotive Sampling System (NASS) Crashworthiness Data System (CDS) for the years 1998 through 2004. The NASS/CDS was initially screened for SUV rollover collisions, then screened to eliminate soft top vehicles, such as the Jeep Wrangler and Suzuki Samurai. The injury data was further limited to driving age teens and adults (age 16 and older) in the front outboard seating positions.

Vehicle Linear and Rotational Acceleration, Velocity and Displacement during Staged Rollover Collisions

Four full scale vehicle rollover tests, about the roll axis (X-axis), were staged using a sled attached to a large truck. Each vehicle was fitted with a nine-accelerometer array that approximated the center of gravity and two single axis accelerometers attached to the roof adjacent to the A-pillar/roof junction. The acceleration data was retrieved for three tests; however, the data recorder malfunctioned on the remaining test. Data was collected at 1000 hertz and processed to determine the linear and rotational acceleration with respect to each of the three vehicle coordinate axes. Rollover video and scene data were also collected to correlate vehicle rollover motion with the accelerometer data.
