A three-dimensional model of finite element method and boundary element method for computing vibration and acoustic radiation from the limited cylindrical pipe shell has been established. The pipe shell’s modes have been analyzed by the finite element modal analysis and experimental modal analysis. The modal analysis results with ANSYS FEM software will be imported into BEM software SYSNOIS, then under the fluid - structure coupling radiation using the software BEM SYSNOISE calculates the pipeline model’s sound radiated power level and studies the different restrictions、thickness and damping for the effects of the pipe vibration and acoustic radiation. Some suggestions which can reduce structural vibration and acoustic radiation are given out.
