Vehicle Linear and Rotational Acceleration, Velocity and Displacement during Staged Rollover Collisions 2007-01-0732

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.
