摘要

研究了浮式海上风力机在波浪、流和风荷载作用下的刚体响应和弹性运动。基于格林函数的线性衍射理论和叶片单元动量法，分别在频域上建立了小流速的数值计算方法和气动分析方法。将该方法与有限元方法相结合，得到了FOWTs的水弹性和气弹性运动。考虑了波-流-风组合与SPAR、半潜式和驳船的相互作用。将三种FOWTs对波浪和风的刚体响应与有电流荷载时的刚体响应进行了比较。此外，本文还研究了流速和入射波与流风的失向对波导运动的影响。讨论了考虑波流相互作用和气动载荷对所考虑的气动动力系统响应的重要性。结果表明，当外加电流荷载时，SPAR - FOWT对波浪和风的运动变化最大。最后，研究了波浪-流-风相互作用对柔性fowt弹性运动的影响，并与刚体fowt进行了比较。

Wave–current–wind interaction with elastic floating offshore wind turbines

This study is concerned with rigid-body responses and elastic motion of floating offshore wind turbines (FOWTs) under combined wave, current and wind loads. A numerical approach is developed in frequency domain based on the linear diffraction theory with a Green function for small current speeds and the blade-element momentum method for hydrodynamic and aerodynamic analysis, respectively. This approach is coupled with the finite-element method to obtain the hydro- and aeroelastic motion of FOWTs. The interaction of combined wave–current–wind with three FOWTs, namely SPAR, semisubmersible and barge, is considered. Rigid-body responses of the three FOWTs to waves and wind are compared to those when current loads are present. Furthermore, the effect of current speed and misalignment of incident waves with current-wind on the motion of the FOWTs is investigated. Discussion is provided on the importance of considering wave–current interaction together with aerodynamic loads on the responses of the considered FOWTs. It is observed that the motion of the SPAR FOWT to combined waves and wind changes the most when the current loads are added. Finally, the effect of wave–current-wind interaction on the elastic motion of flexible FOWTs is investigated and compared with their rigid-body counterparts.
