漂浮式风力机Spar平台抑制摇荡运动研究

Research on Suppressing Swinging Motion of Spar Platform Floating Wind Turbine

平台稳定性是风力机安全运行的基础保障,以Spar平台为研究对象建立整机模型,在其底部设置摇荡阻尼器,基于水动力学软件并结合有限元方法,研究其在风波载荷作用下的时频域动态响应特性,并与原始Spar平台时域响应进行对比。结果表明:较之于原始Spar平台,摇荡阻尼器对改进后平台的垂荡响应抑制效果最为明显,纵摇次之,纵荡最小。

Platform stability is the basic guarantee for the safe operation of wind turbines.For this reason,the Spar platform is used as the research object to establish the whole machine model,and the swaying damper is set at the bottom.Based on the hydrodynamic software combined with the finite element method,the wind and wave is studied.Time-frequency domain dynamic response characteristics under load are compared with the original Spar platform time domain response.The results show that compared with the original Spar platform,the swaying damper has the most evident effect on the suppression of the heave response of the improved platform,followed by the less suppression on pitch,and the smallest one on surge.
