畸形波对SPAR型浮式风力机基础的影响
Effects of freak waves on a SPAR-type FOWT foundation
摘要
Abstract
The time history of freak wave elevation was generated by the phase modulation method.The motion of the SPAR-type floating wind turbine under a freak wave was simulated in the time domain,and the motion law of its floating foundation was analyzed.Results show that the surge and pitch of the SPAR-type floating foundation is more sensitive to the fluctuation of freak waves.The freak wave with a significant fluctuation will increase the first surge peak of the SPAR-type floating foundation,decrease the second surge peak,and increase the pitch amplitude.The first surge peak shows a weak nonlinear increasing trend with the increase of the fluctuation degree.When the fluctuation degree increases by 5%,the first surge amplitude increases by 5.3%compared with the original freak wave,and the pitch amplitude increases by 5.4%compared with the original freak wave.The freak wave with a more significant impact height will reduce the pitch of the floating foundation,and the influence on the surge is not apparent.When the impact height increases by 5%,the pitch amplitude decreases by 2.3%compared with the original freak wave.关键词
