摘　　要：为解决现有航海模拟器中船浪运动分离导致的视景感受体验差的问题,开发了一套船浪实时交互的船舶运动可视化仿真系统.通过海浪谱建模技术构建海面波浪运动场景;在建立船舶受力模型的基础上,通过检测船舶与水面的碰撞实现船舶对波浪力的响应以计算船舶对波浪运动的实时响应姿态变化;同时为增强仿真系统的真实感,使用波动公式计算船舶与水体碰撞产生的水波及其扩散增强模拟真实感.船浪运动耦合的航海模拟器与传统航海模拟器相比,在大海况条件下能够为使用者提供更加真实的视景与运动体验.研究成果视景真实感强,船浪交互实时性好,对于恶劣航海条件下的航海过程有良好的仿真效果.To solve the poor visual experience caused by the uncoupled ship-wave motion in existing navigation simulators,this study develops a set of visual simulation systems for real-time interaction between ship and wave motion.Firstly,the wave motion scene is built by wave spectrum modeling technology.Then,based on building the ship force model,the ship’s response to wave force is realized by collision detection between the ship and the water surface to calculate the real-time response attitude of the ship to wave motion.Meanwhile,the wave formula is adopted to calculate the water wave generated by the collision between the ship and the water body and its diffusion and enhance the realism of the simulation system.Compared with traditional navigation simulators,the navigation simulator coupled with shipwave motion can provide more realistic visual and sports experience in high level sea conditions.The results indicate strong visual realism and sound real-time interaction between ship and wave,with a sound simulation effect on the navigation in bad navigation conditions.
