| 摘 要： | 为研究漂浮式风力机驳船式平台的动态响应,建立基于ITI Energy Barge平台的NREL 5MW漂浮式风力机模型。通过辐射/衍射理论并结合有限元方法,调用水动力学软件AQWA,考虑风、浪、流环境的联合作用,对平台的动态响应进行数值模拟分析,得到了各波浪力随波浪频率的变化及平台在纵荡、垂荡和纵摇方向上的动态响应。结果表明:平台在低频波浪时容易出现较大响应;随着海洋环境恶劣程度的增加,平台的动态响应增大;平台在垂荡方向RAOs要大于纵荡方向。

| Abstract: | To research the dynamic response of barge of platform floating wind turbine, the paper built the machine models of NREL 5MW wind turbine based on ITI Energy Barge platform. Through radiation/diffraction theory and combining with the finite element method,using water dynamics software AWQA,considering the joint action of wind, wave and flow,it carried out numerical simulation analysis on the dynamic response of platform.The paper also got he change of wave forces along with wave frequency and the dynamic response acting on the platform in the surge, heave and pitch direction. The results show that the platform is easy to appear larger response when it is in low frequency waves; When the marine environment becomes worse, the dynamic response of the platform increases; RAOs of the platform in the direction of heave is bigger than that in surge direction. |
