Prediction of the Acoustic Field of Box Type Vibrating Bodies by FEM-BEM

Yu Xingzhuo Fang Xing Zhou Yu  
A new method based on the Helmholtz integral equation is presented to predict the a-coustic radiation field of vibrating bodies by combining the finite element method (FEM) with boundary element method (BEM). The predicting formulation is valid for all frequencies if an extra equation is added. The acoustic field of the box type vibrating bodies has been calculated and measured. The effectiveness of the method has been proved by test results.
