| Abstract: | Finite element method(FEM) is used to calculate the vibration of the structure,and boundary element method(BEM) is used to solve the acoustic radiation problem.On this basis,optimization model of cylinder shell structure is presented and calculation formula of acoustic radiation sensitivity analysis of structural vibration is deduced with emphasis.Acoustic radiation power is considered as objective function.Not only acoustic indexes but also structural indexes are considered as constraints,such as average p... |
