| Abstract: | The problem of the influence of stiffeners layout on acoustic radiation of stiffened plate under fluid-loaded and optimization is considered in the paper.Finite element method(FEM) is used to obtain the structural frequency response and boundary element method(BEM) is adopted to perform exterior acoustic radiation analysis.The acoustic radiation power is defined as objective functional in optimization equation.In order to find optimal stiffeners position on plate and stiffeners size parameter,the genetic al... |
