In order to validate a Hybrid III dummy analytical simulation data set, a sled impact test was simulated in which both a Part 572 dummy and a Hybrid III dummy were used. Each dummy was restrained with a three-point belt system during the 32G sled test. The Crash Victim Simulator (CVS )/Articulated Total Body (ATB) model simulations were set up to reflect the same conditions as in the test and the previously developed standard Part 572 and the newly developed Hybrid III dummy body data sets were used. Graphics of the dummies' motion from the simulation are compared with films of the sled test. Accelerometer and load cell data from both the test and simulations are also used to demonstrate the validity of the CVS/ATB model for simulating the Hybrid III dummy dynamics.

In order to understand an occupant's often violent and complicated motion during rollover accidents, the motion of an anthropomorphic dummy was predicted dynamically using 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.
