摘　　要：为了研究大型单桩式海洋风电装置风振效应较为显著的原因,利用p-y曲线法考虑结构的桩土相互作用,理论分析了风-结构流固耦合的原理与特性,并通过ADINA软件建立了“风轮-机舱-塔架-基础”整机的数值模型,对风电装置整机结构的风致振动问题进行了数值模拟,并与现场监测数据进行对比。结果表明,数值模态分析与现场监测结果较为吻合,考虑流固耦合效应的风致风电机整机结构的动力响应数值分析与现场振动监测结果较为接近,且趋势一致。研究成果证明了文中提出的整机数值模型和数值风洞对风电机整机结构进行风振分析的可行性与可靠性,可为风电装置结构设计及振动控制仿真研究提供科学依据,为类似工程结构的风振分析提供借鉴。In order to find the reasons why the wind vibration effect of the large single-pile offshore wind power installation is more significant,the pile-soil interaction of the structure is considered using the p-y curve,the principle and characteristics of the wind-structure fluid-structure coupling are theoretically analyzed.The numerical model of the"wind wheel-cabin-tower-foundation"machine model is established by the ADINA software and used to simulate the wind-induced vibration of the whole machine model.The comparative analysis with the on-site monitoring data shows that the numerical modal analysis and field monitoring results is relatively consistent.The numerical analysis of the dynamic response of the wind-induced wind turbine structure considering the fluid-solid coupling effect is close to the on-site monitoring vibration results,and the trend is consistent.The research results show that the whole machine numerical model and the numerical wind tunnel proposed in this paper are reliable and feasible for wind vibration analysis of the whole wind turbine structure,which provides a scientific basis for the structural design and vibration control simulation research of wind power installations,and have certain reference for wind vibration analysis of similar engineering structures.
