中文摘要：
针对船舶运动的非线性本质，为舵鳍联合系统建立了具有通用性的非线性数学模型。首先基于MMG（Ship Manoeuvring Mathematical Model Group）的建模思想，建立一个包含风、浪、流干扰的4自由度舵鳍联合非线性数学模型，并详细给出了模型涉及的参数及流体动力导数的计算公式。然后利用该模型对“Hual Trooper”号汽车运输船及“Belnor”号散货运输船进行回转试验及Z形试验的仿真，得到了一系列与实船试验曲线接近的仿真曲线。仿真结果说明了该模型的正确性和工程可行性。
英文摘要：
In light of nonlinear nature of ship motion, a generic nonlinear mathematical model for rudder/fin joint system is constructed. A rudder/fin joint nonlinear mathematical model of four degrees of freedom including wind, wave and current is built firstly based on MMG modelling method, and calculation formulas about the parameters and hydrodynamic derivatives involved in the model are given in detail. Then, by using the nonlinear model, the simulations of turning tests and zigzag tests on ＂Hual Trooper＂ car carrier and ＂Belnor＂ bulk carrier are carried out, and a series of simulation curves that are close to prototype curves is obtained. Simulation results show correctness and feasibility of the model for engineering.
