Comparison between rea l-world injury patterns and ATO (Anthropometric Test Devices) responses in regulated crash tests and FEM Simulations

The biofidelity of crash dummies and their injury prediction capability in a controlled collision environment has always been a matter of discussion. The comparison between ATD responses in a crash test and occupant injury severity in real-world accidents is not trivial. Modern crash dummies, such as THOR and World-SID, could help predicting injury in body regions and in load directions where previous dummies could not. However, the use of standardized ATDs prevents biomechanical variability of real vehicle occupants in terms of gender, weight, height and age from being considered when assessing crashworthiness. The aim is to develop a methodology to compare the injury severity at body region level in real -world crashes and the injury criteria for ATDs in standardized crash tests. Through this study it should be possible to identify and quantify the Reverso del Anexo A differences between injury patterns in the field and the dummy responses in standard crash tests when varying parameters such as the collision angle, the impact speed or the age of the occupant. The methodology should be developed for different crash configurations and different A TOs using real-world accident data, as well as crash-test and simulation data.
