摘要
现行航海类教育模式下学员普遍缺乏对航海知识的总体把握和对船上设备、仪器的操作实践,有必要开发不受时间和场地限制的整船仿真训练平台。基于船舶操纵性分离建模理论建立船舶运动六自由度数学模型;运用柔性物体模拟技术、海浪建模绘制技术以及反向动力学技术实现了船舶场景漫游和船上设备交互;从仿真结果来看,平台运行效率较高,场景沉浸感良好,可以展现大部分航海知识,并可对船上设备和仪器进行实际操作,平台可用于航海类学员的教学与培训。
Under the current navigation education mode,it is common that trainees lack the overall navigation knowledge and the operation practice on onboard equipment and instruments.It is necessary to develop a whole ship simulation training platform that is not limited by time and sites.The six-degree freedom mathematical model of ship motion is established by using the separation modeling theory of ship maneuverability.The flexible object simulation technology,the modeling and rendering of ocean wave technology,and the reverse dynamics technology are adopted to realize the ship scene roaming and equipment interaction.The simulation results show that the platform has high operation efficiency and a good sense of scene immersion,and can provide most of the navigation knowledge and practical experience on equipment and instruments.The platform can be used in teaching and training the navigation trainees.
