摘　　要：文章基于一种新的理论方法和经验公式方法对波浪增阻进行预报,通过比较分析给出了一种改进的工程实用的计算公式。势流理论方法由于存在假设在短波增阻预报上精度不高,而经验方法的船型适用性不强。文中选取VLCC船迎浪航行为例,考虑吃水和航速影响进行了计算验证和比较分析。一种水平线段移动脉动源的三维面元法被用于求解速度势问题,进而采用三维船体辐射能量法得到船舶辐射增阻,基于二阶波浪力定常分量公式计算得到绕射增阻;经验方法采用ISO15016-2015推荐的STAWAVE2方法。通过辐射和绕射增阻曲线分析,对方法的适用性进行分析,进而对半经验方法的修正系数进行了研究,给出了反应相似船船型和航速特征的改进公式。A practical method for engineering prediction is presented based on investigation on comparison of results obtained from a modern theory method and empirical formulas.Due to the hypothesis and predigesting,theoretical methods could not make good accurate prediction for added resistance due to short waves,and empirical formulas are limited to special hull forms.VLCC ships at constant speed in head waves are calculated and analyzed comparably,and the effects of draft and speed are taken into account.A 3-D panel method based on the Green function of translating and pulsating source on the horizontal line segments is used to solve potential theory.Added resistance due to the radiation is obtained by 3D radiation energy method,and that due to the diffraction is obtained by the second order steady-state force equation.STAWAVE2 method recommended by ISO15016-2015 is adopted as the semi-empirical method.The applicability of the present methods is discussed on the basis of analysis of the added resistance due to radiation and diffraction.The revised semi-empirical method is derived after numerical calculations are conducted.Finally,the revised formulas which reflect the characteristics of geosim hull forms are presented.
