FINITE ELEMENT MODELLING AND ANALYSIS OF THORAX/RESTRAINT SYSTEM INTERACTION

Various modelling techniques are playing an increasingly important role as a cost effective means of supplementing crashworthiness data for gaining a better understanding of the injury mechanisms associated with automotive crashes. The interaction of a geometrically accurate (50th percentile male) finite element model (FEM) of the human thorax, and FEMs of a seat belt restraint system and an airbag are examined. Optimization of the thorax model under frontal impact conditions and the development of an improved shoulder structure are discussed. Using the LSDYNA3D three-dimensional FE structural analysis code, stress fields within the thorax model are examined. The results, using each restraint system in a comparable impact environment, are presented. (A) For the covering abstract of the conference see IRRD 894848.
