摘　　要：以某散货船为研究对象,利用泰勒展开边界元方法对目标船在低速和高速下的波浪增阻进行计算,将计算结果与耐波性模型试验结果进行对比分析。分析结果表明,该数值计算的结果与模型试验结果规律性一致,高航速下的计算结果与试验结果基本吻合,低航速下的计算结果略大于试验值。验证了该数值计算方法的可行性,采用该方法进行最小装机功率要求下波浪增阻的评估较为保守。The wave added resistances at four speeds of a bulk carrier are calculated with Taylor expansion boundary element method. Comparison analysis shows that results from calculation and that from model tests well agree with each other at rela- tively high speeds, which proves the feasibility of the numerical method. The calculated results at lower speed are slightly lar- ger than the experimental values. Therefore, the method is conservative in evaluating the wave added resistance for setting the minimum propulsion power.
