This research was performed under two separate phases. The Phase I objective was to evaluate new head designs for the three-year-old child test dummy. Six different heads were fabricated with various density materials for the skulls in an effort to find a design which would indicate higher impact stiffness properties than current heads when tested under impact conditions. A new accelerometer mount was also evaluated. Head drop tests and standard head calibration tests were performed according to the Part 572, Subpart C Regulations. The head final design, which showed superior performance, was a fiberglass skull model containing a 0.5 inch thick vinyl skin. The Phase II work involved the dynamic sled testing of the final fiberglass head design. The new head, which was mated with a standard three-year-old child dummy torso, was tested beside a standard child dummy on the sled. Tests were performed with both Century Love seats and Ford Tot-Guard child restraints at 30 mph. The new fiberglass head indicated performance levels that were within approximately 4.6% of the standard head measurements.
