摘　　要：基于三体船船模系列阻力试验结果,以非均匀B样条拟合船模阻力试验数据随航速变化关系曲线,采用模长界限控制的Gram-Schmidt正交化方法建立给定排水量和航速三体船阻力与侧体位置关系的回归模型,该方法能够快速而有效地获取有效范围内任意给定航速下三体船阻力随侧体位置的变化关系,具有一定的理论意义和较高的工程实用价值。By using Non-Uniform-B-Spline to express Schmidt method with finite condition,the regression of the the resistance curve and adopting the Gramrelationship 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.
