Abstract
This paper describes a bumper system design that satisfies both current FMVSS legislation as well as the European Enhanced Vehicle Safety Committee (EEVC) requirements for lower leg pedestrian impact protection. The dual performance solution is achieved through a combination of material properties and design. Using Computer Aided Engineering (CAE) modeling, the performance of an injection molded energy absorber (EA) was analyzed for pedestrian protection requirements of knee bending angle, knee shear displacement, and tibia acceleration, 4Kph pendulum and barrier impacts (ECE42, FMVSS), and 8Kph pendulum and barrier impacts (CMVSS, FMVSS).
The results demonstrate how an injection molded EA using polycarbonate/polybutyelene terephthalate (PC/PBT) resin (Figure 1) can meet both FMVSS and pedestrian safety requirements and can do so within a packaging space typical of today's vehicle styling.
