Development of the methodology to reconstruct driver injury risks based on real accidents
The purpose of current paper is to present an injury risk reconstruction methodology by using computer simulation so as to investigate the occupant kinematics and the injury causation in a real accident. This reconstruction was made for the case of a driver injured in a real passenger-car-to-tree accident selected from GIDAS (Germany In-Depth Accident Study) database by using finite element method (FEM) and multi-body (MB) kinematics. First of all, the accident dynamics was reconstructed by PC-Crash according to the information from selected accident. Further the FE impact model was developed and used in conditions of PC-Crash results regarding initial impact velocity and impact angle. Three FE simulations were performed and results from one simulation that reproduced the best by comparing the vehicle body deformations, changes of velocity and energy was selected to further MADYMO simulation. In this simulation the effective impact pulse from FE simulation was employed as the input condition to reconstruct driver injury risk. The results show that the driver kinematics and injury risk in collisions can be well reconstructed by the methodology used in the study. This method can provide not only an effective way to evaluate and analyze the protection effect of vehicle in real accidents, but also can be used in research on risks of occupant injury.
