Abstract

Comsol Multiphysics, Va One, Abaqus and Actran were compared to be used as the software for cabin acoustics simulations in NOVI SP2. Actran was selected to be used as a FEM program in frequency domain, using Biot's model for absorptive materials. CAD data was simplified and repaired, and the mesh was done in Ansys. The modes and the eigenfrequencies of empty cabin, calculated with Abaqus and Actran, are very consistent. The calculated sound field distributions with internal loudspeaker excitation are rather similar to the measured ones. A general modeling flowchart for vibroacoustic simulations has been developed in the project.
