Modal Analysis of Structural-Acoustic Coupling for a Passenger Car

Abstract:

Due to the interaction of structure and acoustic cavity, the frequency and mode shapes of the structure and acoustic cavity are different from their natural mode. To perform the dynamic characteristic of the passenger car more accurately, a structural-acoustic coupling model was established to analysis its modes. The result is benefit for the later optimal design of acoustic.
