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.
