In this thesis, a simplified FE system was modelled in order to reproduces a frontal full-width impact test of a mid-size sedan, according to EuroNCAP regulation. The FE environment simulates the interior of a 2012 Toyota Camry and can accommodate a driver Human Body Model (HBM). Staring from a full-scale vehicle model provided by CCSA, a modelling effort was performed in order to simulate an actual reverse-firing sled with detailed interiors. In particular, the pulse motion of the system was derived from the kinematics of the complete car, monitoring them over the crash test. The model was validate performing two comparison between the sled and full-scale model in different scenarios:​ with and without a human model in driver configuration. Before including the HBM into the simulation, several steps were performed in order to set properly the simulations. The human body was positioned in standard driver posture inside the vehicle, then, the sitting footprint was created on the seat and finally, the seatbelt was fitted to secure the driver occupant. In the first comparison, a high similarity in behaviour of model structures was found. The second comparison showed a good correspondence between models even if a slight difference in human motion is detected. Overall, the sled system behaves in a realistic way with respect to the complete vehicle model, making it a good tool for the evaluation of safety devices and the prediction of injuries and trauma on human body. Moreover, this model allows to reduce computational time of the simulation with respect to a full-scale model and allows to change set-up of the vehicle in easiest way.
