融合数值流场的内河船舶三维航行虚拟现实系统

为缓解船舶驾驶员在航行环境复杂水域的心理压力,提高船舶航行安全,使船舶驾驶员更直观准确地利用两岸地形及根据航道尺度、桥梁通航尺度、水流态势等情况航行,采用虚拟现实技术对船舶三维航行环境进行了仿真。以长江重庆主城区段水域为例,在对该水域流场的数值模拟的基础上,构建了融合数值流场的船舶三维航行环境。仿真结果表明:所研制的系统对船舶航行环境具有逼真的可视化效果,可有效地提高航行安全和缓解驾驶员心理压力。

Virtual Reality System for Inland Ship Navigation by Coupling Numerical Simulation Model of Flow with Three-dimensional Simulation Platform

The ship’s three-dimensional navigation environment was simulated by the virtual reality technology in order to ease the psychological pressure of the ship pilots navigating in the complex waters and improve the navigational safety.What’s more,the simulation could help the ship pilots make good use of waterway form and navigation scale such as channel dimension,bridge scale for navigation,and water flow situation,etc,intuitively and accurately to navigate.Taking the waters adjacent to Changjiang and Jialing Rivers Interjunction in Chongqing as an example,the three-dimensional navigation environment amalgamating numerical flow field was constructed based on the numerical simulation of flow filed.The simulation results show that the developed system can effectively improve the safety of navigation and ease the psychological pressure of the pilot because of the fidelity and visualization of the simulated ship’s navigation environment.
