摘　　要：为抑制定桩式海上风机在风、浪和地震联合激励下的动态响应,文中对被动调谐质量阻尼器(TMD)和主动TMD系统进行设计,并对其响应抑制效果进行仿真分析。首先,借助多体动力学软件SIMPACK建立了定桩式海上风机模型;其次,在仅保留塔筒1阶前后弯曲自由度和TMD纵向运动自由度的基础上,基于系统辨识技术建立风机降阶模型;然后,对被动式TMD和主动TMD系统进行设计;最后,在泊机状态下,评估控制系统对桩基前后弯矩和塔顶前后加速度的抑制效果。结果表明:被动TMD和主动TMD均可以有效抑制桩基前后弯矩和塔顶前后加速度最大值;相比于被动TMD,主动TMD在需要消耗控制功率的同时控制效果更好。In this article,in order to suppress the dynamic response of the bottom-fixed offshore wind turbine with the combined excitations of wind,wave and earthquake,a passive tuned mass damper(TMD)system and an active TMD system are designed,and their response suppression effect is simulated and analyzed.Firstly,a model of the bottom-fixed offshore wind turbine is set up through the multi-body dynamic software SIMPACK.Besides,a reduced-order model of the wind turbine is constructed by the technology of system identification,merely with the tower first-order fore-aft degree of freedom(DOF)and the longitudinal TMD DOF.Next,both the passive TMD and active TMD systems are designed.Finally,under the parked condition,efforts are made to evaluate the response suppression effect of the two TMD systems on the monopile-base fore-aft bending moment and the tower-top fore-aft acceleration.The results show that both the passive TMD and active TMD systems can effectively suppress the maximum values of the monopile-base fore-aft bending moment and the tower-top fore-aft acceleration.Compared with the passive TMD system,the active TMD system enjoys better performance while the control power is consumed.
