| Abstract: | This paper mainly discussed a numeric method of fast prediction of the vibration and sound radiation of complicated double cylinder shell underwater based on indirect boundary element method(IBEM).Firstly,the IBEM method is used on the calculation of the vibration and sound radiation of a single cylinder shell,compared with the analytical method and commonly used numeric methods nowadays,the structure finite element method coupled with the fluid finite element method(FEM-FEM)and the structure finite element... |
