Abstract

A primary cause of severe injury experienced by a pedestrian who is impacted by the front of a vehicle consists in the head impact on the hood during the loading phase of the accident. Impact speed and vehicle front geometry are the most important factors which govern the severity of this impact. The aim of the present study is to analyse the motion patterns occuring during impact, particularly those of the head, and to identify a favourable front geometry in view of a reduced injury hazard. The investigations are based on impact tests performed on a sled with a vehicle front having a variable front geometry and at different impact speeds. The surrogate was a modified 572 ATD (HUMANOID) equipped with 18 accelerometers and whose head trajectory during impact was determined by high-speed cine-photogrammetry.
