摘　　要：为了更加准确地预报实船的阻力性能,在计算兴波阻力时考虑了船体和螺旋桨相互作用.对基本Rankine源法进行改进,船体周围的流场速度势可以表示成4部分:叠模绕流速度势、考虑自由面影响的波动速度势、螺旋桨对船体的干涉而产生的速度势和螺旋桨涡格子模型诱导速度势.以Hess-Smith法计算的叠模绕流解作为基本解,进行迭代计算,直至收敛.并编制了相应的数值计算程序,以26 000 t成品油船的模型为例进行分析比较,获得了令人满意的结果.The use of a numerical calculation method for resistance provides needed feedback for predicting the resistance performance of a full-scale ship more accurately. The study emphasized interaction of the propeller and hull form and modification of the basic Rankine source method. Velocity potential around a ship hull expressed as a sum of the basis velocity potential of double model flow, perturbed wave potential with free-surface effect, velocity potential of the interaction of the propeller, and induced velocity potential of vortex lattice model were also key in the examination of the study. Solving the interaction problem between the hull and the propeller relied on the numerical iterative procedure, using the Hess-Smith solution for the source distribution of the hull surface of the double model approximated ship as the basic flow. The numerical calculation study had great results as evidenced by the success of the 26000DWT model, which had good resistance and test value.
