Nowadays, finite element analysis is used widely in crashes simulations in order to determine the deformation, stress and dynamic behavior of the vehicle during the impact. A finite element model of a chassis frame and frontal bumper is developed. The frontal crash simulation between the chassis frame is fully simulated using Radioss explicit integration solver. The proposed model is simulated under frontal collision with a rigid wall in the first case and in the second case with a rigid pole. In both cases the resultant deformations and stresses are determined for an initial velocity of 15m/s. The results of this simulation can be used to assess the damage of the observed model and to investigate new ways to optimize the frame design.
