Validation of a human FE lower limb model for a child pedestrian against accident data

Due to the lack of sufficient data for children, validation of the impact response of a child dummy or a child finite element (FE) model is a big challenge. This study used multi-body simulations along with optimization techniques for estimating impact conditions of a particular child pedestrian accident case selected from an in-depth pedestrian accident database. FE child model simulations with failure criteria were run using the estimated impact conditions, and the predicted and observed injuries were compared. The results of the comparison showed that the model can predict the lower limb injuries described in the accident data within the estimated bone material property variation.
