设计了超大型油船组系试验方案，采用多元二次正交多项式对组系试验结果进行回归分析，获得了剩余阻力系数、兴波阻力系数、湿表面积、形状因子、自航因子的回归公式，并结合702所“八五”组系回归结果对浮心纵向位置和船宽吃水比进行修正。编制了阻力、自航因子的估算程序并绘制了试验图谱，估算结果经过校核，准确可靠，能够反映现代新船型的水动力性能特点。%In the paper, model tests of VLCC series were designed. Based on model tests results, regression formulas for residual resistance coefficient, wave-making resistance coefficient, wetted surface, form factor and self-propulsion factor were obtained with multiple and orthogonal quadratic polynomial regressions. Longitudinal center of buoyancy and ratio of beam to draft in the regression formulas was amended according to the series of tests in the Eighth Five-Year Plan. A program for estimating ship resistance and self-propulsion factor was workout, and digital charts of series of tests were drawn. It is shown that numerical estimation is exact and reliable, and is able to reflect hydrodynamics performance of modern ships.
