The Development of Experimental Head Impact Procedures for Simulating Pedestrian Head Injury

This paper describes the procedures and methodologies used to reconstruct cadaver test head impacts and pedestrian accident cases, respectively. Head impact dent depth and its relationship to impact energy was found to be useful in determining the effective head mass upon impact in the cadaver test reconstructions. Good correlation between impactor response and the cadaver head accelerations was achieved. Good correlation was also achieved between pedestrian accident case injuries and the reconstruction results using three different head injury criterion, HIC, Mean Strain Criterion (MSC), and Normalized G's.
