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.
