中文摘要：在Fudide-Krylov假设条件下,依据船舶分离建模理论在固定和运动坐标系中计算海面船只六自由度运动数学模型。主要包括:对风、浪、流的单独建模并进行矢量叠加,并在风浪流联合作用下对船舶六自由度运动构建简化的数学建模,完成实时仿真。基于Simulink和V-Realm Builder虚拟现实技术创建船舶运动模型、海洋表面环境及船只的几何模型,对船舶六自由度运动进行视景仿真,给出了有风无浪、有浪无风和风浪兼有三种情况下船只旋回路径和船舶运动轨迹。在VR视景浏览器中创建动态海面上船舶六自由度运动模型,不仅易于实现且结果逼真。得到的结果为进一步研究动态船只目标声散射特性的精确预报提供基础。

外文摘要：Under the assumption of the Fudide-Krylov hypothesis, mathematical model of the six-degree-of-freedom motion of the ship on the surface of sea is established, which is constructed and calculated based on the separation modeling theory in the static and moving coordinate systems. The main contents of the paper include:modeling wind, wave, and flow separately, and then performing vector superposition, and further constructing a simplified mathematical model of six-degree-of-freedom ship motion under the combined action of wind and waves. The purpose of this work is to achieve real-time simulation. Based on the Simulink and V-Realm Builder,namely virtual reality technology in MATLAB, the researchers created the ship movement model, the sea surface environment and the ship’s geometric model. The visual simulation of the ship’s six degrees of freedom movement is given under three kinds of situations. The ship’s rotation path and movement trajectory are described when there is wind and no waves, there is wares and no wind, and there is wind and wave, respectively. The research results can provide the basis for further research on the accurate prediction of the acoustic scattering characteristics of dynamic targets.
