摘要： Barge型浮式风机是发展海上风电的重要装备，其运动响应可以通过被动控制装置调谐质量阻尼器（tuned mass damper， TMD）有效抑制。基于ITI Energy Barge风机，本研究设计了新型Barge浮式风机基础，建立平台配置TMD的风机动力学模型，在浮动平台内配置不同位置、质量、阻尼参数TMD，研究风浪载荷作用下风机平台配置最优参数TMD前后浮式风机运动响应的变化。结果表明：在新型风机平台内浮筒顶部配置质量比3%、阻尼比6%的TMD后，风机塔顶前后和左右位移分别减小15.56%、 44.93%，平台纵摇和横摇抑制率达到22.97%、 62.79%，风机塔基前后和左右弯矩分别减少15.62%、 39.8%。此时，TMD控制效果最佳，风机整体稳定性大幅提高。

Abstract: Barge-type floating wind turbine is an important equipment for the development of offshore wind power， and its motion response can be effectively suppressed by a passive control device tuned mass damper (tuned mass damper， TMD). Based on the ITI Energy Barge wind turbine， this study designs a new Barge floating wind turbine foundation， establishes a wind turbine dynamic model configured with TMD in the platform， configures TMDs with different positions， masses， and damping parameters in the floating platform， and studies the change of the motion response of the floating wind turbine before and after the TMD with optimal parameters configured on the wind turbine platform under the action of wind and wave loads. The results show that after the TMD with a mass ratio of 3% and a damping ratio of 6% is configured on the top of the buoy in the new wind turbine platform， the front and rear and left and right displacements of the top of the wind turbine tower are reduced by 15.56% and 44.93% respectively. The pitch and roll suppression rate of the platform reaches 22.97% and 62.79%. The front and rear and left and right bending moments of the fan tower base are reduced by 15.62% and 39.8% respectively. At this time， the control effect of TMD is the best， and the overall stability of the wind turbine is greatly improved.
