| Abstract: | This paper presents a computer simulation on acoustic contribution of vibrating body panels. The structure-acoustic coupled models of Santana 2000 are built both with and without absorption material, and ANSYS finite element analysis software is used to calculate interior acoustic pressure due to panels vibration under specific frequency, then the acoustic contribution of panel is evaluated. |
