Development, Optimization, and Design for Robustness of a Novel FMVSS 201U Energy Absorber

Abstract

Introduction: Significant opportunity to improve vehicle occupant safety. Reduce impact severity between occupant heads and vehicle interiors. Rigid body panels. Used plastic deformation of mild steel fins and cover sheet to absorb impact energy. It's possible to very efficiently optimize an energy. Conclusions: It's possible to very efficiently optimize an energy absorber design using the LS-DYNA explicit finite element code and the successive response surface method algorithm. Use of classic factorial techniques in combination with Kriging response surfaces can guide improvement of product robustness and offer insight into the nature of a product and its performance variability. An enlightened combination of these techniques enables, if nothing else, valuable and relatively inexpensive insight into the feasibility and behavior of various design concepts.
