| Abstract: | A nonlinear dynamic model for complete vehicle as an acoustic-structure interaction system is established by using free-interface component modal synthesis for substructures with linear and nonlinear link. And a numerical simulation is performed on interior noise generated by the excitation of engine using the model. The simulation results are verified by test under same conditions. |
