Step to Step Approach to a Standardized Full Scale Pedestrian Test Methodology 830058

This report describes the steps to a standardized full scale test methodology, which is needed for the next step, namely the development of a simple and reproducible method to prove the performance of vehicle structures in pedestrian accidents, e.g. by body segment impactor tests. A first project consisted in a literature study by TNO+ which gave the main input data for the test method, as e.g. car shapes, standing positions of the pedestrian and impact speeds. Further on 7 cadaver tests were carried out by ONSER+ and 24 dummy tests were carried out with a Hybrid II adult dummy and a 6 years old child dummy at the BASt+. These tests were the data base for dummy improvements to get a better correspondence in dummy kinematics and loads. In a second project the adult pedestrian dummy was equipped in one case with a HSRI side impact thorax and in the other case with an APR (82) side impact thorax. 16 tests were performed with these dummies which had also modified knee joints allowing a lateral bending of the knees of 30°. The modified knees led to a more realistic bending of the legs around the car shape and to a longer wrap around distance of the dummies. Dummy specific kinematics are described and loads are compared.
