Abstract

Prasad and Mertz published head injury risk curves for skull fracture and for Abbreviated Injury Scale (AIS) ${\geq}4$ brain injury due to forehead impacts based on the 15 ms HIC criterion. KNCAP adopted the HIC36 criterion for the male dummy and the HIC15 criterion for the female dummy. In this paper, it was studied that which of the HIC15 and HIC36 was more effective for the male dummy head injury evaluation. The frontal US-NCAP data for the 7 vehicles from the NHTSA test database were used to evaluate the head injuries. In the case of using the HIC15 and evaluation range 250~700, the discrimination of the rating for the occupant head injury was increased.
