用线性兴波阻力理论计算穿浪双体船的兴波阻力

Calculation of wave-making resistance of wave-piercing catamarans by means of linear wave-making resistance theory

以线性兴波阻力理论 (薄船理论 )Michell型兴波阻力计算公式为基础 ,结合穿浪双体船的船型特点 ,建立了一次和二次简化的Michell型兴波阻力计算公式 ,并以此简化公式计算了某穿浪双体船WPC×××的兴波阻力 .将计算结果与马丁法计算结果进行了比较 ,并探讨了兴波阻力规律及片体间距对WPC兴波阻力的影响规律 .

Based on the Michell formula of the thin-ship theory and considering the underwater ship form of WPCs, a linear simplified Michell formula and a quadratic simplified Michell formula are suggested. The wave-making resistance of WPC××× is calculated by means of this method. Its results are compared with ones obtained from Martin computation method, and the wave-making resistance regulations of WPC are investigated.
