摘　　要：由于水深限制,传统的Spar型浮式风机并不适用于我国沿海浅海海域。为了推进浮式风机在我国的实际应用,本文提出一种新型浅吃水Spar型浮式风机。针对不同的关键设计参数,进行频域水动力分析,根据短期预报的结果,选出最优结构关键参数。分别研究该新型浅吃水浮式风机在作业海况和生存海况下的运动性能,建立浮式风机系统的气动-水动-系泊全耦合数值分析模型,基于叶素动量理论计算风机系统的气动载荷,采用势流理论计算水动力载荷。从计算结果可以看出,无论是在作业海况还是生存海况,新型浅吃水Spar型浮式风机摇摆减小,运动性能良好,系缆张力满足设计要求。结果表明:加装沉箱的新型Spar型浮式风机,改善了Spar风机对吃水深度的限制,可以在浅水海域有效运行。Due to water depth limitations,the traditional spar type floating wind turbines are not suitable for shallow coastal waters in China,in order to promoting the practical application of floating wind turbines in China,one of new Spar type floating wind turbine is proposed in the shallow water.Targeting different key design parameters,the frequency domain hydrodynamic response are analyzed,the optimal structural key parameters selected based on the results forecasts of short-term.The motion performance of the new shallow draft floating wind turbine are studied under operating and survival sea conditions separately,the fully coupled numerical analysis model of aerodynamics,hydrodynamics,and mooring is established for a floating wind turbine system,the aerodynamic load of a fan system is calculated based on blade element momentum theory,and the hydrodynamics load is solved based on the pretention flow theory.The results indicate that the sway is reduced for new shallow draft Spar type floating wind turbine,motion performance is good,a new Spar floating wind turbine can effectively operate in the shallow water.
