The invention belongs to the related technical field of vibration control, and discloses a multi-frequency self-adaptive vibration reduction floating platform and an offshore wind power system.The floating platform comprises a platform body, and the inner space of the platform body is divided into a plurality of mutually-independent compartments through partition plates; the compartments are used for containing water to form TLDs, then the vibration reduction effect on the platform body is achieved through shaking of the water, the multiple compartments form multiple stages of TLDs, the setting parameters of the water in the compartments corresponding to the different stages of TLDs are different, and the multiple stages of TLDs correspond to the multiple stages of vibration frequencies of the platform body. The interior of the platform body is divided into a plurality of compartments, the compartments are used for containing water, the multi-direction self-adaptive vibration reduction effect of the floating platform can be achieved through oscillation excitation of water flow in the random direction, vibration reduction of multiple vibration frequencies can be achieved through the compartments, the problem that most existing TMDs are single in direction and frequency is effectively solved, and the service life of the TMDs is prolonged. And for the complex movement of the floating platform, the method has better practicability.

    本发明属于振动控制相关技术领域,其公开了一种多频率自适应减振的漂浮平台及海上风电系统,其中漂浮平台包括平台本体,平台本体的内部空间通过隔板分隔形成多个相互独立的隔间,隔间用于容纳水以形成TLD进而通过水的晃动实现对平台本体的减振效果,且多个隔间形成有多阶TLD,不同阶TLD对应的隔间中水的设置参数不同,多阶TLD对应平台本体的多阶振动频率。本发明将平台本体内部分隔形成多个隔间,隔间用于装水,利用水流随机方向的晃荡激励,可以实现浮式平台在多方向的自适应减振效果,其分隔隔间可实现对多个振动频率的减振,有效解决了现有大多数TMD单一方向、单一频率的问题,对于漂浮平台的复杂运动,具有较好的实用性。
