| Abstract: | The basic methods of simulation analysis on interior noise of a fuel cell car using finite element method(FEM) are discussed,including the acoustic modal analysis on passenger compartment,the calculation on structural modes of car body,and the analysis on structure-acoustic coupling.The simulation analysis reveals the causes of severe noise of fuel cell car at low frequencies. |
