摘　　要：利用Michell线性兴波理论,从单体船的波谱函数出发推广到多体船,推导了多体船兴波阻力计算公式,并将计算结果与试验结果进行了比较,计算兴波阻力结果可以反映试验趋势,有效马力比较接近于试验结果,可以为多体船的方案优选提供依据。A method for calculating the wave-making resistance of a multi-hull ship is put forward based on the Michell linear wave resistance theory, which extends the wave spectrum function of mono-hull ship to the multi-hull ship. The calculation result is compared with the one of experiment, which shows that the result can reflect the trend of test about wave-making resistance and the effective horsepower is adjacent to result of experiment calculation on the whole. The method is able to estimate the optimization of multi-hull ship according to the wave-making resistance.
