| Abstract: | By using Non-Uniform-B-Spline to express the resistance curve and adopting the Gram-Schmidt method with finite condition,the regression of the relationship between the trimaran resistance and the side hull position was made,which is based on a series trimaran model experiment results.With the method put forward,the resistance of the trimaran with certain displacement and speed could be calculated quickly,and it is useful to solve such kind of problem of engineering design. |
