A Study on Biofidelity of EEVC Adult Headform Impactor Using Human Head FE Model and Real World Injury Data

The present paper investigates the biofidelity of EEVC adult headform impactor using human head FE model and real world injury data. Eight real world car-pedestrian accident reconstructions were conducted for assessment of biofidelity of the EEVC headform impactor. The outputs including head linear acceleration and HIC value were compared between EEVC headform impactor and human head model simulations. The results showed that the EEVC adult headform impactor has an acceptable biofidelity for evaluation of vehicle safety performance. The human head model and in-depth accident investigation are valuable approaches for evaluation of the biofidelity of the headform impactor. The results from the present study could be used as background knowledge for improving the biofidelity of EEVC adult headform impactor.
