摘要
针对50 m作业水深提出了一种新型铰接式基础海上风力机结构,建立了铰接式基础风力机(AOWT)摇摆运动分析模型。采用空气动力-水动力耦合分析方法,利用MATLAB软件在时域内编写运动控制方程,对风、浪、流不同环境载荷作用下铰接式基础风力机的动力响应进行分析,在此基础上,进一步研究湍流风对风力机整体运动及载荷响应影响。计算结果表明,额定风速海况下,铰接式基础风力机运动及载荷性能良好,满足结构设计要求。相比于定常风情况,湍流风作用下,系统响应均值显著减小,但幅值变化加大,且在低频范围内诱发较大共振。
Here,a new type of articulated offshore wind turbine(AOWT)structure was proposed for 50 m operating water depth,and the swing motion analysis model of AOWT was established.Adopting the aerodynamic-hydrodynamic coupled analysis method,the motion control equation was coded in time domain using the software MATLAB to analyze dynamic responses of AOWT under different environmental loads of wind,wave and flow.Then,effects of turbulent wind on the overall motion and load response of AOWT were further studied.The calculation results showed that AOWT has good motion and load performance under the rated wind speed and sea conditions,and meets the structural design requirements;compared with the steady wind,the mean value of AOWT response decreases significantly under turbulent wind,but its amplitude variation increases,and a larger resonance is induced within low frequency range.
