摘要

近海船舶受到海浪和海流的扰动，可能导致船舶倾覆事故，需要对其进行研究。本文以威格利船舶模型为研究对象，建立了船舶运动的机理模型。采用计算流体力学方法(CFD)和动态网格技术(DGT)对高阶斯托克波代替正弦波作为输入波的船舶运动过程进行了分析。结果表明，高阶斯托克波具有非对称分布，可以利用CFD方法和基于高阶斯托克波的DGT来研究舰船运动。仿真结果为六自由度波浪中船舶运动和船舶阻力研究提供了基础。

Simulations and Analysis on the Course of a Ship Motion Based on CFD and DGT with High-order Stoke Wave

An offshore ship suffers from unmatched disturbance caused by sea waves and currents, which may cause ship overturn accidents and need to be studied. In the paper, the Wigley ship model is taken as the research object and a mechanism model of the ship motion is established. CFD(Computational Fluid Dynamics) method and DGT (Dynamic Grid Technology) are used to analyze the course of a ship motion with high-order stoke wave which can replace sine wave as the input wave. The results show that high-order stoke wave is asymmetrically distributed and the ship motion can be studied by using CFD method and DGT based on high-order stoke wave. The simulation provides a foundation on ship motion in six-degree-of-freedom waves and on the ship's resistance study.
