Abstract In this study, the software ANSYS ICEM CFD and HYPERMESH was used to develop a finite element (FE) model for 10 year old child head with detailed anatomical characteristics. The MADYMO models of crash dummies were used to simulate the dynamic responses of an injured child in a typical falling accident from three different heights, and the motion parameters of orientation and velocity of the child head at the moment of impact were calculated. These parameters were input into the 10 year old child head finite element model to simulate the head response during the fall impact and analyze the injuryrelated biomechanics parameters. Results showed that the location of maximum vonmises stress and maximum vonmises strain in the skull matched well with the impact site located on the right side of the occipital, but within their limits of tolerance. The intracranial pressure could accurately predict the injury level, while the vonmises stress could approximately recognize the traumatic location. The accident reconstruction results indicate that the constructed model has a good biofidelity and can be used for the further study of the child head injury mechanism.
