摘要

综合半潜式、Spar式、张力腿式浮式风机基础的特点，提出一种新型全潜式浮式风机基础，并采用FAST软件耦合水动力-空气动力-控制系统-系泊系统对不同风况下的浮式风机及全潜式浮式基础的动力特性进行分析。分析结果表明全潜式浮式风机塔筒的自振频率及基础六自由度的自振频率能够较好的避开常见海浪的频率及风机运行频率1P、3P等。全潜式浮式风机在不同风况下具有较好的运动特性，全潜式浮式风机基础在不同风况下的横荡、垂荡、纵摇与风机在不同风速下受到的推力相关。

Abstract

Synthesizing the advantages of the semi-submersible,Spar and TLP types of floating offshore wind turbine foundations,a new type of submersible foundation for floating wind turbines was put forward.A coupled dynamic analysis of the wind turbine and its submersible foundation in different wind conditions was carried out by using the FAST software.The results show that the natural frequencies of the tower combined with the submersible foundation are of no coincidence with the normal wave frequencies and the 1P and 3P operating frequencies of the wind turbine.The surge and pitch of the submersible foundation are correlated with the wind turbine thrust force in different wind conditions.
