Abstract
Designing a kind of noise insulation Polycarbonate pane is an important object to provide the maximum comfort during driving in Automobile. This paper investigates noise transmitted into rectangular cavity through polycarbonate pane. This transmission phenomenon is a typical fluid-structure interaction problem. The coupling analysis of cavity-pane system is modeled by combining the modes of simply supported pane and cavity modes. The numerical results reveals that noise attenuation can be realized by appropriate selection of structural parameters such as the damping of structural and cavity, the thickness of the pane, and density of viscoelastic core material.
