Abstract:

In order to understand an occupants often violent and complicated motion during rollover accidents, the motion of an anthropomorphic dummy was predicted dynamically using the Articulated Total Body model, a human body gross motion simulation program. The accuracy of the predicted motion was established by its favorable comparison to that recorded on high speed film during a 60 mph crash in which the vehicle rolled over four times. This vehicle motion was then modified to six other rollover crash situations for computer simulation. Significant changes in the predicted occupant motion were readily observed. Differences were also observed in occupant accelerations and impact and belt forces. Keywords Computer simulation, Modeling, Biodynamics.
