| 摘 要： | 将VV＆A技术引入了海浪仿真研究。首先比较了线性叠加法和线性滤波法并对其仿真结果进行了校核，然后验证了仿真结果，并讨论了谱窗估计和最大熵谱估计两种方法在海浪谱仿真验证中的可用性，最后通过在PC机和工作站上的大量仿真试验分析了海浪视景实时仿真相匹配的网格、频率等参数的选择对帧时间的影响。研究表明上述结果在海浪仿真、验证和视景生成方面具有参考应用价值。

| Abstract: | The theory and technicals of verification,validation and accreditation(VV&A) are applied to wave simulation.The linear superposition method and the linear filtering method were compared which wereused to simulate random ocean wave based on JONSWAP spectrum.The spectrum of wave height sequence of a fixed point was verified and validated by compareing with JONSWAP spectrum.The simulation wave data by linear superposition method was used in 3D visual ocean wave simulation and the real-time characteristic was analyzed by testing frame on PC and Workstation. |
