Experimental Development of Pedestrian Head Injury Tolerance Data

This paper presents the results of an experimental program in which the head induced damage from real world pedestrian accidents was reproduced with an impactor. An accident investigation study aimed at obtaining the necessary information for reconstructing pedestrian accidents is discussed. Results of preliminary impact tests in which the mass and velocity of the impactor were varied are presented. Impactor output from reconstructions of the head-induced damage from 24 pedestrian accidents is related to the head injury sustained by the pedestrian in the accident. The paper concludes that it is feasible to use a head form impactor for the development of pedestrian head injury tolerance data.
