Abstract
To demonstrate the Articulated Total Body (ATB) model's capability to predict complex rollover accidents, a rollover accident was selected from the National Accident Sampling System (NASS) and simulated. This paper focuses on the simulation of the vehicle's dynamics which can in turn be used to specify the vehicle motion for occupant simulations. The selected accident case involved a pickup truck, crashing at high speed and completing three rolls. The simulation results compared well with the accident description and diagrams in the NASS report. The study demonstrates that the ATB model can be used to provide a reasonable prediction of the vehicle's motion during a rollover accident using the data available in the NASS report.
