Self-adaptive active and passive hybrid tuned mass damper for offshore wind turbine vibration control
The invention discloses a self-adaptive active and passive hybrid tuned mass damper for offshore wind turbine vibration control. The damper comprises at least one set of self-adaptive variable dampingpassive control system, a self-adaptive variable direction active control system and a control system which are arranged at the maximum amplitude of a vibration mode controlled in a wind turbine tower. Each of the self-adaptive variable damping passive control systems comprises a reciprocating motion unit and a variable damping unit. According to the self-adaptive active and passive hybrid tunedmass damper for offshore wind turbine vibration control, the corresponding vibration control system can be started according to different vibration degrees of the wind turbine tower; the self-adaptivevariable damping passive control systems can instantaneously adjust the flowing state of magnetorheological damping liquid by utilizing the instantaneous rheological property of the magnetorheological damping liquid, so that the vibration energy of a wind turbine is consumed in time, the time lag problem of a traditional vibration control device is solved, and the safe operation of the wind turbine is ensured; and the self-adaptive variable direction active control system can immediately adjust the direction of output control force by electrically driving a rolling support, so that the control reliability is high, and the effect is good.
本发明公开了一种海上风机振动控制的自适应主被动混合调谐质量阻尼器，包括设置在风机塔筒内部所控振型最大振幅处的至少一组自适应变阻尼被动控制系统、自适应可变向主动控制系统和控制系统；所述自适应变阻尼被动控制系统包括往复运动单元和变阻尼单元。可根据风机塔筒的不同振动程度启动相应的振动控制系统，其中自适应变阻尼被动控制系统利用磁流变阻尼液的瞬时流变特性，可瞬时调整磁流变阻尼液的流动状态，及时消耗风机的振动能量，改善了传统振动控制装置的时滞问题，保障风机安全运行；自适应可变向主动控制系统能即时通过电驱动滚动支座调整输出控制力的方向，控制可靠性高、效果好。
