摘要
通过对Noblesse的新细长体理论进行改进 ,使之适用于卵型船等多体船型的船型特点 .利用该方法计算了卵型船的兴波阻力 ,并将计算结果与实验数据进行比较 ,得到令人满意的结果 .同时研究了线积分项和限制基元波波陡对于兴波阻力计算结果的影响 .此外还考虑了三体船型的水下片体的位置的优化问题 。
The wavemaking resistance of a new type of trimaran-Ovoid-type Hullform,which was proposed by some Japanese researchers,was calculated using a method based on Noblesse's New Slender-ship Theory.Between the numerical results and the experimental data the comparisons were made,which show satisfactory agreement,especially in high speed range.In addition,the effects of line integral and restricting the wave-steepness of the elementary waves were estimated numerically.Also,the optimization of outer hulls location of the trimaran for minimizing wavemaking resistance was considered.Some useful conclusions were obtained.
