| Abstract: | According to the characteristic of the bottom structure of a naval ship,this paper studies a designmethod to avoid load-frequencies. Some problems including the choice of design parameters,the determination ofdesign procedure and optimization method,etc. are analysed. A numerical example is given to illustrate the effectiveness of the present method. |
