Abstract: The research on the injury during head-and-hood collision is important in determining the safety factors during the collision of pedestrians and cars. The problem is simplified in this paper to the collision of a flexible ball and an elastic plate with large deflection. With FEM, the dynamic response during head-and-hood collision is analyzed, based on which the influences of different factors on collision response are obtained. Finally, some guidance is put forward for designing the hood, which may have the function of protecting pedestrians.

Key words: flexible ball, big deflection elastic plate, FEM, dynamic response
