摘要
海洋工程领域中的浮式结构物设计，需要精确计算海浪载荷，保证满足稳定性和安全性。该文利用MATLAB对Longuet—Higgins长峰波海浪模型和三维不规则短峰波随机海浪模型进行了仿真研究。结果表明，利用海浪谱来模拟三维随机海浪能够得到比较精确的海浪波面图和波高值，进一步根据流体的势流理论就可以分析计算出该结构物受到的海浪载荷，为校验结构物的结构强度提供了必要的基础。
The load on offshore structure generated by waves should be computed accurately, in order to keep the offshore struc- ture stability and security in the structure design in the ocean engineering. The mathematical models of Longuet-Higgins long crested waves and 3-D irregular short crested waves were learned in this paper by using MATLAB. The results showed that more precise wave map and wave height value can be gotten by using wave spectrum theory to simulate 3-D irregular wave.
