Title
(EN) Hybrid damping module, vibration suppression device, vibration suppression method and wind power generation set
(ZH) 混合阻尼模块、振动抑制装置、抑振方法及风力发电机组
Abstract
(EN) The invention provides a hybrid damping module, a vibration suppression device, a vibration suppression method and a wind power generation set, the hybrid damping module comprises a first damping unitand a second damping unit, wherein the first damping unit comprises a rotor part and a stator part arranged in a form of being parallel to the rotor part, moreover, the rotor part is configured to beable to rotate relative to the stator part so as to generate electromagnetic damping, and a runner is formed in at least one of the rotor part and the stator part; the second damping unit comprises aliquid damper, the liquid damper is communicated with the runner and forms a circulation loop, and the liquid in the liquid damper can circularly flow in the circulation loop. According to the hybriddamping module provided by the invention, on one hand, a composite vibration suppression solution combined with TMD and TLD is provided, by combined usage of the TMD and the TLD, vibration suppression effect of the hybrid damping module can be improved, and on the other hand, a problem of damping force attenuation caused by temperature rise is solved for a permanent magnet eddy-current damping device.
(ZH) 本发明提供一种混合阻尼模块、振动抑制装置、抑振方法及风力发电机组,混合阻尼模块包括:第一阻尼单元,第一阻尼单元包括转子部和与转子部平行设置的定子部,并且转子部被构造为能够相对于定子部转动以产生电磁阻尼,转子部和定子部中的至少一者中形成有流道;第二阻尼单元,第二阻尼单元包括液体阻尼器,液体阻尼器与流道连通并且形成循环回路,液体阻尼器中的液体能够在循环回路中循环流动。根据本发明的混合阻尼模块,一方面提出了一种结合TMD、TLD的复合抑振解决方案,通过TMD、TLD组合使用,可提高混合阻尼模块的抑制振动的效果,另一方面解决了永磁涡流阻尼装置由于温升阻尼力衰减的问题。
