The complete Finite Element Model of vehicle with dummy inside is established.Through analyzing structure deformation and acceleration of the vehicle, the rule of energy absorption and dissipation is obtained, the dummy's respond and the collision capability criteria of the head, chest and thigh are achieved.A comprehensive and credible appraisement about the frontal crash process and crashworthiness is proposed by analyzing the effect of the main energy-absorbing components, the transmitted route of the energy and the safety of the vehicle and occupant injury criterions.
