Summary:

The worldwide involvement in global technical regulation (GTR)discussion shows the increasing importance of pedestrian safety asa global concern. In the US, bumper systems are designed for thePart 581 bumper standard and IIHS (Insurance Institute of HighwaySafety) bumper structural test protocols. There has also beendiscussion in the North American automotive industry about themerits of incorporating some measure of pedestrian protection intotheir systems as well. Compliance with the potential pedestrian legrequirements creates a design conflict with current bumperdamageability standards and possibly CAFÉ laws. The difficulties ofdesigning a bumper system that is rigid enough to protect thevehicle in low speed crashes and, at the same time, compliantenough to protect a pedestrian raise questions as to whether theseideas are compatible.This paper presents reasonable means by which to manage lowerleg impact, Part 581 bumper standards and IIHS bumper damageabilityassessment criteria in a styling and cost structure way, which istypical of today's automotive industry. The proposed approachis validated over a generic vehicle platform through extensivecomputer-aided engineering (CAE) and subsystem level testing
