Simplified FE (finite element) model about heavy commercial vehicle cab and acoustic cavity are built in this paper. They are verified through the modal analysis and modal test. Then a acoustic-structure coupled model is formed. Modal analysis is performed using MSC. Nastran. It is shown from the simulation result that the modes of coupled system reflect both the characteristics of structural and cave model. Meanwhile, excitations received from road test are acted to the acoustic-structure… CONTINUE READING
