Summary:

Tractor cab interior noise has been predicted by using a numerical method whereby cab structural and acoustic characteristics are described, respectively, by finite element and boundary element models. The spectral vibrational data measured below cab isolation mounts is used as mechanical excitations to cab-mount system. Responses on each grid point are calculated in structural analysis and subsequently converted to velocity boundary conditions in acoustic prediction of interior noise. The analytical results match reasonably well with the measured regarding cab vibration and the noise level at operator ear. Panel contribution analysis is also performed to examine the relative importance of concerned portions of cab structure or enclosure
