GREATER USE OF ALUMINIUM IN PASSENGER CARS. POSSIBLE CONSEQUENCES FOR ROAD SAFETY

MEER GEBRUIK VAN ALUMINIUM IN PERSONENAUTO'S. MOGELIJKE CONSEQUENTIES VOOR DE VERKEERSVEILIGHEID

The aim of this study is to investigate the consequences of applying a greater aluminium proportion to passenger cars. The study investigated the following: (1) the weight reduction influence on the vehicle dynamics; and (2) how this would affect the safety of both occupant and collision partner, in the event of a collision. Based on mechanical principles, it was shown that the maximum acceleration and deceleration which can be attained by a vehicle are not dependent on its weight. The material used for the panelling of cars influences the collision outcome for vulnerable road users such as pedestrians and cyclists. The material properties of aluminium are in this respect more favourable than those of steel. The considerable energy-absorbing capacity of aluminium also has a positive effect on the occupant safety. The studies into vehicle weight reduction influence on road safety by using statistics were carried out in the United States. The study briefly describes the role of the Dutch national and European government in applying aluminium in vehicles. The predicted weight reduction is 10%, if more aluminium is incorporated in motor vehicles. It is anticipated that this reduction will not have any negative consequences for road safety, provided that the vehicle mass distribution does not increase.
