摘要
针对船舶驾驶模拟器模拟的逼真度要求,研究船舶对操舵后的动态响应。建立了风、流共同作用下船舶操纵系统的动力学数学模型,该数学模型为动态响应线性型;利用已知的某船型的主机参数和船形尺寸参数,求出所需的相关量,建立船舶运动仿真模型并进行相关试验的仿真。模拟了船舶回转性的试验和风、流共同作用下对船舶操纵性能的影响试验,使船舶操作者进一步了解船舶回转性的特性以及风、流对于船舶航迹的影响。将该模型与船舶驾驶模拟器结合,用于驾驶模拟器模拟船舶操舵后的视觉仿真,使使用者感觉其操纵特性更加逼真。
According to the fidelity requirements of the ship driving simulator＇s simulation, this article mainly studies the dynamic response of the ship to the steering. First, establish the dynamic model of the ship under the influence of the wind and flow. The mathematical model belongs to the dynamic response of the linear type. Second, use the known ship＇ s parameters to calculate the related values. Third, establish a simulation model based on Simulink to simulate the influence of the wind and flow on the ship maneuvering capability, in the meantime simulate the associated tests. We simulate the test of the ship rotation and the impact tests of ship handling performance under the wind flow influence. So that it can make the operator better understand the characteristics of the ship rotation and the wind flow＇s influence on the ship track. The combination of the model with driving simulator is mainly used to simulate the visual simulation after steering through the ship simulator, thus the users feel more realistic about its handling characteristics.
