摘　　要：针对研究船舶各种运动状态,为有效验证控制器的功能提供有效平台。采用船舶运动可视化,对视景仿真系统进行开发,对各种常见的建模和驱动技术进行了重点研究。提出了船舶运动视景仿真系统的整体设计方案及流程,利用建模软件Creator建立了逼真的三维船舶实体模型,采用DOF节点技术建立了舵\翼舵、鳍\翼鳍及螺旋桨的活动模型;解决了视景仿真系统开发中的视点切换、多通道显示、仿真数据加载等关键问题;基于VC++集成开发环境和Vega API编程技术开发了系统。三维仿真结果表明系统具有较好交互性和逼真度,为船舶运动特性研究提供了可靠手段。Study a variety of ship motion states, in order to provide a platform for the effective verification of the controller function. The scene simulation systems were developed by using ship motion visualization, and commonly used models and driving technologies used in developing scene simulation systems were studied. An overall design and process of the scene simulation system of ship motion were proposed, A realistic 3D model of ship was built based on the modeling software Creator. The movable models of main/flap rudder, main/flap fin and propeller were estab- lished using the DOF node technology. The key technologies of scene simulation system were resolved, such as viewpoint switching, multi-channel showing, simulation data loading. The scene simulation system was implemented through the combination of the Vega API programming technology and the language environment of VC ＋ ＋. Finally, three-dimensional simulation results demonstrate the good interactive and fidelity of the system. A reliable means has been provided for studying characteristics of ship motions.
