【摘要】 随着超大型船舶的出现,船舶波浪增阻对船舶航行经济性的影响更加明显,因此在船型开发中波浪增阻预报也更加受到重视。本文基于有航速三维频域方法求解耐波性问题,进而采用有航速三维船体辐射能量法得到船舶辐射增阻,通过Salvensen方法修正绕射作用引起的增阻。选取ITTC推荐的S175集装箱船船型为计算对象,通过试验数据对比验证了方法的准确性。讨论了在不同频率与航速下不同增阻成分,并基于切片理论和GB(Gerritsma&Beukelman)方法计算结果对比分析,验证了该方法的工程实用性。更多还原

【Abstract】 With the very large ships appearing the added resistance in wave has a more obvious influence in the economy of the ship navigation, therefore the added resistance is laid more emphasis on for the purpose of hull form development. In the present paper, 3D frequency method with forward speed is used to solve the seakeeping problem and then 3D method of radiation energy is used to get ship added resistance due to radiation. Added resistance due to diffraction is calculated by Salvensen method. The method is validated in accordance with the results from the experiment data of S175 container ship recommended by ITTC, and comparison analysis is performed with Joosen method and Gerritsma and Beukelman(GB) method based on the strip method,which shows the applicability of the numerical method.更多还原
