摘　　要：该文利用Michell线性兴波理论,从单体船的波谱函数出发,依据波谱函数的可叠加性推广到多体船,推导了单体船、双体船、三体船、四体船以及五体船的兴波阻力计算公式,给出了各种多体船型兴波干扰成分的研究,并将相关船型的阻力计算结果与试验结果进行了对比,比较表明计算的兴波阻力结果可以反映试验趋势,有效功率比较接近于试验结果,可以为方案论证阶段多体船的方案选优提供依据。The paper presents a method for calculating the wave-making resistance of multi-hull ships, which is based on the Michell linear wave resistance theory and extends the wave spectrum function of mono-hull ship to the multi-hull ship. The formula is able to predict the wave-making resistance of mono-hull, catamaran, trimaran, tetramaran and pentamaran, and the interaction drag. The calculated results are compared with those of the experiments. It shows that globally the trend of the calculated wave-making resistance is essentially following that of experiments, and the calculated effective power is adjacent to the results of experiment. During concept design, the method is applicable to find a better multi-hull form based on the wave-making resistance.
