摘　　要：基于高速三体船线性兴波阻力离散点源型数值计算方法,用正交设计法初步优选侧体主尺度参数和布局参数,进一步将模长限制的多元正交回归计算方法与正交设计法结合,得到了单位排水量总阻力关于侧体布局和主尺度参数的回归公式,据此探讨了高速三体船侧体布局和主尺度参数优化问题。Based on the linear numerical calculation method of the discrete source point style for the calculation of the wave resistance of high speed trimarans, the principal dimension parameters and the disposition parameters are optimized preliminarily.Furthermore, by combining the orthogonal design method with the multivariate orthogonal regression method of limited modules,the regression formula related with the total resistance of unit displacement weight vs the principal dimension parameters and the disposition parameters is obtained,according to which the optimum state of the principal dimension parameters and the disposition parameters of the high speed trimarans is discussed.
