| Abstract: | Based on the theory of spectral direct calculation,the method of estimating the shape parameter of Weibull distribution was given.Take one trimaran as an example,the characteristic of trimaran’ shape parameter was discussed.The results show that the sea state has an important influence on the trimaran’s shape parameter of Weibull,and the value in the connection of the main hull and wet-deck at the middle of the cross-deck is larger.The result gives an important reference for trimaran’s structure design. |
