| Abstract: | The continuous structure＇s acoustic radiation power sensitivity and acoustic optimization problems under external loading are investigated herein. Finite element method （FEM） is used to ob- tain the structural frequency response and boundary element method （BEM） is adopted to perform ex- terior acoustic radiation analysis. Combination the Taylor expansion function, the structural-acoustic power sensitivity information is applied in structural-acoustic optimization analysis. In the end, the stiffened double cylindrical shell in water is demonstrated numerically, the result show that the meth- od is feasible and effective. |
