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。
To research the dynamic response of barge of platform floating wind turbine , the paper built the machine models of NREL 5 MW 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 dy-namic 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 .
