摘要采用计算流体动力学（CFD）和刚体动力学耦合方法，对粘性流体中的船舶六自由度操纵进行了分析。在简要介绍该方法的基础上，讨论了舵、桨、船体及其相互作用的建模问题。船舶和方向舵采用几何模型，螺旋桨采用体积力模型。进行了稳态漂移试验以及回转圆和Z字形机动试验。与实验数据的比较表明，良好的协议。
Abstract A coupled method of Computational Fluid Dynamics (CFD) and rigid body dynamics is employed to analyze ship maneuvers with six degrees of freedom in viscous fluid. After a brief introduction to the method, the issues of modeling the rudder, propeller, hull and their interaction are discussed. While the ship and rudder are modeled geometrically, the propeller is simulated by a body force model. Steady drift tests as well as turning circle and Zigzag maneuvers are performed. Comparison with experimental data shows good agreement.
