摘要
将分段幂多项式拟合方法与线性兴波阻力理论相结合,提出一种针对复杂线型小水线面双体船的兴波阻力数值计算方法,该方法应用于常规小水线面双体船的兴波阻力计算,表明该方法能在常规的幂多项式拟合方法的基础上进一步提高计算精度,同时也验证了该方法的正确性,将该方法的计算结果与复杂线型小水线面双体船剩余阻力的试验结果相比,两者吻合较好,证明了该方法用于复杂线型小水线面双体船的兴波阻力计算是可行的。
The numerical method which combines the pie-ewise power polynomial approximation with the linear wave-making resistance is defined to compute the wave-making resistance of the small waterplane area twin hull (SWATH) with complicated hull line. The wave-making resistance of a conventional SWATH model is calculated by this method. The result shows that the precision can be improved compared with the conventional numerical method of power polynomial approximation, and it also shows that this numerical method is correct. The results calculated by this method are consistent with those of resistance test of a SWATH model with complicated hull line, which indicates that such a method is feasible to compute wave-making resistance of the SWATH with complicated hull line.
