| 摘 要： | 针对救助船消防训练中存在的海况复杂,对外消防炮射流受风影响大,往往无法准确控制其射向目标区域的问题,在理想状态下射流理论的基础上探究风对射流轨迹的影响,建立自然风条件下射流轨迹的数学模型,模拟对外消防炮射流的运动情况。应用3ds Max构建船舶模型,用Unity3D构建救助船在面临大风浪、遇险船着火等状况时对外消防系统的工作场景,提出一种精确构建粒子系统轨迹的方法,使射流模型能精确体现在场景中。通过虚拟现实设备能实现救助船对外消防培训仿真系统的立体显示和人机交互,起到更好的虚拟仿真和培训效果。

| Abstract: | In the fire fighting training of rescue ships under complex sea conditions, the water jet of external fire fighting guns is influenced greatly by wind, so that it often can not control target area accurately. In view of the problem, the influence of wind on jet trajectories is analyzed based on the jet theory of the ideal state, and the mathematical model of the jet trajectory under the condition of natural wind is established to simulate the movement of water jet of external fire fighting guns. The ship model is constructed by 3ds Max.By Unity 3D, the working scenes of the fire fighting system of rescue ships under the conditions of large wind wave and fire of ships in distress are constructed, and a method for accurately constructing the trajectory of the particle system is proposed, so that the jet model can be accurately shown in the scenes.The 3D display and human computer interaction of external fire fighting training simulation system of rescue ships can be realized through virtual reality devices, which improve the effect of the virtual simulation and training. |
