摘要
基于船舶摇荡运动的控制理论,建立船舶横摇运动和纵摇运动的状态运动方程,求解出船舶运动姿态,同时建立了横摇与垂荡耦合的时域模型,利用SQL Server数据库存储数据信息,通过OpenGL建立船舶三维模型,用存储的运动姿态数据驱动模型实现运动仿真。本文应用VB建立了可视化程序主界面,在主界面输入真实船舶参数和仿真环境参数,得到二维时域波形图以及三维仿真动态图,从而方便、快捷地实现了实船摇荡运动仿真的可视化,并总结实船摇荡运动规律,为船舶设计提供依据,为船舶的操纵提供建议。
Based on the theory of ship oscillatory motions, the roll and pitch motion equations were established, then the irregular waves were created according to PM spectrum, using Matlab the motions were solved. Meanwhile, the coupled model of roll and heave was studied, the time-domain responses were the basis data of the motions simulation. The 3-D model of ship was established with the techniques of OpenGL, the motions of the model were driven by the above data which were saved in the SQL Server database. The main interface,which was built using VB, is simple, then the visualization of ship motions simulation is achieved. The irregulars of ship oscillatory motions were achieved, which is the basin theory for ship design and the useful suggestions were provided for ship handling in special waters.
