风浪流不共线对半潜式风机平台水动力性能的影响研究
海上浮式风机是在风、浪、流的共同影响下运行的，这些载荷往往作用于不同的方向。现有研究通常只考虑风浪流共线情况，为此本文旨在研究风浪流不共线对浮式风机平台动态响应的影响。以OC4-DeepCwind半潜式平台为研究对象，首先将模拟结果与FAST结果进行了对比分析，验证了数值模型的正确性；然后讨论了风浪流单个环境载荷与另外两个载荷呈0°、30°、60°和90°夹角时浮式风机平台的动态响应的变化。结果表明：风浪流共线时的纵荡运动响应最大；风浪流不共线对平台纵荡运动响应的影响较大，对垂荡运动响应的影响很小；风向角变化对平台运动的影响大于浪向角和流向角。
