摘要
[目的]文章旨在探索 10 MW级半潜型浮式风机的一体化计算方法并分析其在 40～50 m近海深水区的耦合动力响应特性.[方法]以 10 MW混凝土半潜型浮式风机为例,构建一体化时域数值计算模型,统计分析其额定发电和极端工况下的平台动力响应和系泊张力特征.[结果]平台水平运动主要受波浪荷载、风荷载和系泊刚度特性的影响,最大水平运动和系泊张力发生在生存工况,垂向运动主要受波浪荷载影响,摇摆运动的均值主要受风荷载影响,上述浮式风机动力响应均满足设计指标.[结论]一体化数值计算方法较好地考虑浮式风机耦合动力特性,由于水深限制,近海深水区的海上漂浮式风机对水平运动约束和系泊非线性问题的优化更为重要,响应极值主要发生在极端工况,上述结论为此类漂浮式海上风机基础结构的研究与设计工作提供了一定的参考.
Abstract
[Introduction]The research aims to explore the integrated calculation method of a 10 MW semi-submersible floating wind turbine,and analyze its coupled dynamic response characteristics in 40～50 m offshore deep water areas.[Method]A 10 MW concrete semi-submersible floating wind turbine was taken as an example,and then numerical calculation was carried out by the integrated calculation method,and its coupled dynamic response under rated and survival conditions was statistically analyzed.[Result]The horizontal motion of the platform is mainly affected by the wave force,wind loading and mooring stiffness.The maximum value of motion and mooring tension occur in the survival condition,and the heave motion is mainly affected by the wave,but the mean value of the pitch/roll motion is mainly affected by the wind loading,all of which meet the design specification.[Conclusion]The integrated calculation method better considers the coupled dynamic behavior of floating wind turbines.Due to the limitation of water depth,the optimization of horizontal motion and mooring nonlinearity of offshore floating wind turbines is more important in offshore deep water areas,and the extreme response mainly occurs in survival conditions.The above conclusions provide an important reference for the research and design of the floating offshore wind turbines in offshore deep water area.
