Abstract

A vibroacoustic model for Valtra cabin T888 M has been constructed. Cabinet interior and steel + glass + chassis structure model is valid up to 400 Hz with and without the inner roof. Wool is modeled with Biot's model and the inner roof is modeled as solid and as porous Biot material. Modes of empty cabin, the response to an internal loudspeaker, the response to structure-borne sound, the response to external diffuse sound field excitation, and parametric studies for inner roof properties have been simulated. Enhancing material models, increasing frequency range above 400 Hz, virtual testing of different materials, and model auralization are the most important targets for future.
