Abstract
While the efficient FE simulation of solid and fluid materials
in the automotive industry is nowadays a well-assessed process, the
simulation methods for porous materials still have room for
improvement and are difficult to be completely integrated into the
standard vehicle NVH simulation workflow, which in the FE domain of
applicability is typically carried out by means of MSC.Nastran.
Aiming at supporting the effective solution of this problem,
this paper shows the results of a new approach for the FE
simulation of porous layers extensively used in vehicle sound
package soft trim components.
