Dynamic biofidelity of the Part 572 and Hybrid III anthropomorphic test dummy heads

Ward, Carley

Two anthropomorphic test dummy (ATD) heads are evaluated for biodynamic fidelity in a combined experimental and analytical study. In the experimental investigation, a Part 572 head, a Hybrid III head, and a series of cadaver heads were subjected to the same impacts. Blows were delivered by a padded, pneumatically powered impactor to three locations on the head. The area over the frontal and mandible bones were impacted in the midsagittal plane. The side of the head (parietal bone region) was impacted in the lateral direction. Head response measures are compared for impact velocities between 16 and 27.4 km/h. Limitations on the use of ATD head accelerations as human injury predictors are examined. Intracranial pressures are calculated from the head accelerations using a finite element brain model.
