In order to investigate injury mechanisms to the pedestrian pelvis and lower limb, the authors have developed a finite element (FE) human model for the pedestrian pelvis and lower limb in their previous studies. Quasi-static and dynamic responses of the pelvis and lower limb components were individually validated against recently published experiments. However, the pelvis and lower limb models have not been validated at the assembly level under impact conditions that better represent an actual car-pedestrian impact situation. In this study, the pelvis and lower limb models were assembled in a standing position, and an upper body model with rigid body segments connected by mechanical joints was integrated into the FE pelvis and lower limb model assembly to create a full-body pedestrian model. The model was subjected to car impacts at 40 km/h to represent published car-to-pedestrian impact experiments using human subjects.
