This paper systematically expounds mathematical model and computer simulation of ship maneuvering, and use MMG's manipulation of motion mathematic model and related series of experimental results as the foundation,establish the basic model of the single( double) square rudder( streamline rudder, single plate rudder) transport vessels, as well as manipulating movement model in water power, propeller, rudder force and moment,calm water,wind,flow,deduced the non-dimensional eguations set of this model. Using VB program to imitate the gyratory motion of ship, its calculation results are basically accord with the actual situation, the results were analyzed finally.%系统地论述船舶操纵仿真数学模型及计算机模拟,并以MMG操纵运动数学模型及相关的系列实验结果为基础,建立单(双)桨方形舵(流线型舵、单板舵)运输船舶的基本模型,以及在水动力、螺旋桨推力、舵力及其力矩、静水、风、流中的操纵运动模型,导出该模型的无因次化方程组,选择欧拉积分法,积分求解该方程组.利用VB程序模拟了船舶回转运动,其计算结果基本符合实际情况,最后对结果进行了分析.
