Abstract

Numerical prediction plays a key role during the development of new car projects, and definition of dynamic-acoustic behaviour of sound proofing materials is a crucial task in this process, in order to optimize the final noise as well as the weight of the vehicle treatment. Inside the development of a new project, the well-known FSI (Fluid-Structure Interaction) technique, based on FEM models of both car body and cavity has been succesfully applied since the last ten years, but in this simulation system acoustic materials have been taken into account only as acoustic impedances, representing a boundary condition for the fluid-structure interaction.
