Development of a Head Impact Test Procedure for Pedestrian Protection
Published November 04, 1991 by National Highway Traffic Safety Administration in United States
An analysis of the literature yielded a zone of possible head impact points for pedestrians involved in accidents (children and adults) involving head/bonnet impact. For the vehicle impact velocity of 40 km/h specified in the award of this project, it was possible to obtain impact velocities and dent patterns for cadaver tests using full-scale tests.
One head impactor each for child and adult were designed and built, and calibration requirements deduced. Satisfactory results were obtained in a comparison of impactor tests and full-scale cadaver tests. Basic tests were performed on the influence of impactor weight, shape, the necessity of an outer skin, min. bonnet deformation, etc.
