Theoretical study of a motor vehicle-pole impact

This paper presents a theoretical model investigating a car impact with a timber light pole. A theoretical model, even one greatly simplified, that identifies the significant parameters and can be used for routine pole design is a useful tool. The model proposed in this paper, compares its predictions with those of a commercial dynamic analysis package and presents the results of a parameter study that identifies the important pole parameters and quantifies their effect. The parameter study highlights the fact that the act of simply making a pole frangible will not, of its own, reduce vehicle decelerations to levels where car occupants are likely to survive. Pole mass also plays a significant role.
