DEVELOPMENT OF A PLASTIC FRAME MOUNTED BUMPER THAT MEETS THE REQUIREMENTS FOR PEDESTRIAN SAFETY PERFORMANCE

摘要

This paper presents the design and development of a chassis mounted pick-up truck front bumper for the 2018 Ranger Raptor which meets pedestrian safety performance.Truck bumpers are traditionally made of steel to meet customer expectations of a durable vehicle capable of suitable crash protection performance,firmness of feel and rugged styling.Pedestrian safety performance is increasingly becoming a regulation for the sale of vehicles in selected markets around the world.A traditionally mounted steel bumper does not have suitable energy absorption to meet this regulatory requirement.The bumper developed by Ford of Australia uses sandwich plastic bumper fascia with a steel support structure to meet the conflicting requirements of a soft front for pedestrian protection and a solid substructure to meet low speed crash requirements including static and dynamic stiffness for durability.
