Acoustic Sensitivity Study of Structure Acoustic Radiation Baed on BEM Method

ZHANG Jun,ZHAO Wen-zhong(School of Mechanical Engineering,Dalian JiaoTong University,Dalian 116028,China)~()  
Acoustic sensitivity method is developed to perform sensitivity analysis of sound pressure with respect to structure vibration velocity.BEM analysis method and acoustic sensitivity are deduced.Structure dynamic response is calculated by using FEM method,and the vibration velocity achieved in FEM is applied as boundary condition in BEM,the response sound pressure and acoustic sensitivity are calculated by BEM method.The validity of this method is demonstrated through the examples of radiation box.
