Abstract
This paper discusses the modeling of vehicle rollover collisions and resulting occupant motions. MADYMO is used to model a completely instrumented NHTSA dolly rollover collision of a Bronco II. Animated modeled motions are compared to actual video footage of the rollover. Measured acceleration pulses from the test are compared with the computed accelerations of the vehicle center of gravity, and driver head and chest accelerations. Also the vehicle roll velocity test data are compared to the computed values. It was found that there was good agreement between the modeled and test results.
From the results, we discuss the capability to determine the injury of the occupant from the computed results.
