Abstract: A Finite Element (FE) model of the Chalmers-Autoliv pedestrian dummy was developed and validated. The dummy model was used to: investigate the difference in the assessment of head injury risks by the dummy model and by an EEVC adult headform model; to develop and optimise a pedestrian airbag system. The study showed that the head impact conditions and the calculated head injury parameters of the dummy model were different from those of the EEVC headform model. A properly designed airbag system can effectively reduce head injury risks in a pedestrian accident.

Keywords: FEM; finite element method; modelling; pedestrian dummy; headform test; head protection; pedestrian airbags; vehicle safety; pedestrian safety; head injury risks; head injuries; head impact; vehicle accidents; pedestrian accidents.
