Movable stay cable vibration reduction damper and stay cable vibration reduction system
The invention provides a movable stay cable vibration reduction damper and a stay cable vibration reduction system. The movable stay cable vibration reduction damper comprises a damper body, a control circuit board and a plurality of rolling wheels. The damper body is tubular. And the plurality of rollers are arranged in the damper body. The plurality of rollers are matched with the inhaul cable, so that the plurality of rollers can roll along the inhaul cable. The rollers are electrically connected to the control circuit board so that the control circuit board can control rotation of the rollers. During use, the control circuit board controls the rolling wheels to rotate, and then the whole damper moves along the inhaul cable. In practice, the natural vibration frequency of the inhaul cable is determined by the material, interface and length of the inhaul cable. If the external time-varying load frequency is the same as the inherent frequency of the inhaul cable, the inhaul cable can generate resonance. At the moment, if the damper moves along the inhaul cable, on one hand, the vibration length can be changed, and then the natural vibration frequency is changed; and on the other hand, damping can be provided at a more effective position, so that resonance is effectively avoided.
本发明提供了一种可移动的斜拉索减振阻尼器及斜拉索减振系统，包括阻尼器本体、控制电路板和若干滚轮。阻尼器本体呈管状。若干滚轮设置于阻尼器本体的内部。若干滚轮配合于拉索设置，以使若干滚轮能够沿着拉索滚动。滚轮电连接于控制电路板，以使控制电路板控制滚轮的转动。使用时，控制电路板控制滚轮转动，进而使得整个阻尼器沿着拉索移动。实际中，拉索的材料、界面与长度决定其固有振动的频率。如果外部的时变荷载频率与拉索的固有频率相同相同，拉索就会产生共振。此时，若阻尼器沿着拉索移动，一方面可以改变振动长度，进而改变其固有振动频率；另一方面也可以在更有效的位置提供阻尼，从而有效地避免了共振。
