摘要
为了更好地体现航海模拟器中双桨双舵船舶的行为真实感,基于MMG分离建模思想,在考虑船舶大型化、桨/舵安装位置、螺旋桨多工况/逐级变速等情况后,再比较分析模型参数不同求取方法的优劣,构造了一种能够较为精确地描述双桨双舵船舶操纵特性的船舶运动数学模型。根据船舶“MaerskMarie”的仿真结果可知,所构造的双桨双舵船舶运动数学模型与实船试验结果符合度较好,最大误差为16.5%,能够很好地表征双桨双舵船舶的行为真实感。
In order to improve the behavioral realism of the twin-propeller twin-rudder ship in navigation simulation systems,the modeling ideas of MMG were used to modify the mathematical model of large-scale modern ships,considering the effect of propellers/rudders installation positions and the model of the propeller under multi-working conditions or step-by-step variable speed.Different methods of model parameters calculations were analyzed comparatively.The model of the twin-propeller twin-rudder ship was established to analyze its maneuvering characteristics.Simulation results is basically identical with the test results for a real ship,and the maximum error is 16.5%,so this model can simulate the behavioral realism of twin-propeller twin-rudder ships better.
