Abstract

The aim of this research is to analyse real accidents involving a pedestrian or a cyclist from three different approaches: in-depth investigation, numerical simulation with multibody model and experimental reconstitution with PMHS subject. Real accidents chosen from an in-depth investigation are modelled using a multibody approach. Effects of many parameters (car velocity, victim position at impact, etc) are numerically studied in order to find the closest configuration to the presumed real accident conditions. This configuration is then reproduced experimentally by crash-test using cadavers. Finally, the three approaches are compared in terms of impact points on the car, injuries and kinematics. For the covering abstract see ITRD E141569.
