Simulations of Rollover Tests

Abstract

The motion of an occupant during a rollover crash is often Violent and complicated. This motion needs to be studied so as to determine how best to protect an occupant during a rollover crash, and the best tool known is computer models which simulate the motion of an occupant. It was the Air Force's Articulated Total Body (ATB) model which was used. The accuracy of the simulations by this model has to be determined through a limited number of rollover crash tests. Five such tests were conducted under this program using a specially designed rollover test device, and the corresponding simulations of the motion of a dummy occupant are presented. The accuracy of the simulations obtained for these five tests with a rollover test device and the similar accuracy for one full-scale crash test conducted earlier on a different testing program provide confidence that an occupant's motion during a rollover crash, whether belted or unbelted, can be satisfactorily simulated by the Air Forces ATB.
