摘　　要：在原苏联“方尾图谱”重分析和改进的基础上[1],基于兴波阻力的薄船理论与船模试验数据的结合,提出用兰金(Rankine)体的波幅函数代替实际船型的波幅函数,以确定双体船片体间的阻力干扰因子,从而计算得到双体船的兴波阻力。整个计算过程直接使用Microsoft Excel,对新方尾单体船电子阻力数据执行查值和进行主要影响系数的修正计算,粘性影响修正与总阻力计算;进行不同尺度的快速性方案比较,以及确定高速单体船或高速双体船的总阻力与有效功率曲线。通过WP60穿浪双体船一算例与船模试验结果的比较表明,该方法是一种实用、高效、灵活、便捷和可靠的计算方法。Upon weightiness analyzing and improving on original USSR ＂Diagram of transom ships resistance＂,it is put forward that wave amplitude function of reality hull can be replaced by the wave amplitude of Rankine function to calculate wavemaking interfering factor τ between catamaran demi-hulls,and thereby to obtain resistance of high speed displacement catamarans.Resistance data of designed ship and a series ship form corrective coefficients will automatically be looked up from the electron diagram and correction of viscous resistance be calculated by Microsoft Excel in the whole process.The calculation results of an example,WP60, for wavepiercing catamaran show that the method is applied, high efficiency, agile and dependable.
