摘　　要：船-桨-舵相互作用是影响船舶操纵性能的重要因素之一。本文采用RANS方程求解方法并结合SST k-ω湍流模型,计及自由面兴波影响,螺旋桨用体积力法建模,数值模拟了带桨、舵的全附体集装箱船KCS船模的舵力试验、斜拖试验。为研究螺旋桨对操纵运动水动力的影响,分别对带螺旋桨和不带螺旋桨的船-舵系统进行计算,对比了船模水动力随漂角、舵角的变化情况。研究结果表明:带螺旋桨的船-舵系统的水动力和力矩对舵角的变化更加敏感;螺旋桨的运转主要增大了船艉部的横向力;在舵力试验和带舵角的斜拖试验中,螺旋桨对横向力、转艏力矩有显著的影响。The interaction among the hull,the propeller and the rudder is one of the important factors that affect the ship maneuverability.By solving the RANS equations in conjunction with the SST k-ω turbulence model,and taking the free surface wave-making influence into acount,the rudder force test and oblique-towing test of a KCS container ship model appended with a rudder and a propeller are numerically simulated in this paper.The propeller is modeled by the body force method.In order to study the effect of propeller on the ship hydrodynamic force in maneuvering motion,the simulations are conducted for the ship-rudder system with and without propeller respectively,and the hydrodynamic forces on the ship model changing with the drift angle and rudder angle are compared.It shows that the hydrodynamic force and moment of the ship-rudder system with propeller are more sensitive to the change of rudder angle;the operation of the propeller mainly increases the lateral force at the stern.In the rudder force test and oblique-towing test,the propeller has a significant influence on the lateral force and yaw moment.
