Influence of System Boundaries and Boundary C onditions on Pedestrian Protection Head Impact 2009-01-1208

The aim of this project was to determine the most important influences on head impact in pedestrian protection. This means to find out the parameter with the biggest effect on the results and the smallest possible sub system, which can represent the load case satisfying. Secondly strengths and weaknesses of the available development resources (simulation and hardware testing) should be identified respectively improved.
Therefore a series of tests on a vehicle with state-of-theart development for pedestrian protection was carried out. At first the tests were performed according to the regulation 2003/102/EC. Afterwards the velocities and impact angles were varied and the influence of the suspension was considered. Furthermore, tests on modified front hoods were accomplished. Based on the test results the simulation model of the same vehicle was validated using a new visualization method. This finite element model was used to investigate further parameter variations.
