Intelligent tuned mass damper with three-stage variable damping control
The invention provides an intelligent tuned mass damper with three-stage variable damping control. Bidirectional vibration control of a structure is realized through smooth bidirectional sliding of a friction pendulum support in a plane; eddy current damping force is generated through relative movement between the electromagnet and the conductor plate to achieve energy consumption in the small-amplitude vibration control stage, and the energization amount of the electromagnet is adjusted in real time through the control center to achieve semi-active variable damping control. Energy consumption in the medium-amplitude vibration control stage is achieved through shaking of liquid and the variable oil film system, and the oil film thickness of the variable oil film system is adjusted in real time through the control center so that semi-active variable damping control can be achieved; the magneto-rheological damper is used for achieving energy consumption in the large-amplitude vibration control stage, the energization amount of the magneto-rheological damper is adjusted in real time through the control center so that semi-active variable damping control can be achieved, and the limiting effect of the mass block can be achieved.
本发明提供了一种三阶段变阻尼控制的智能调谐质量阻尼器，通过摩擦摆支座在平面内光滑双向滑动以实现结构的双向振动控制；用电磁铁与导体板间的相对运动产生电涡流阻尼力实现小幅振动控制阶段的耗能，并通过控制中枢实时调节电磁铁的通电量以实现半主动变阻尼控制；用液体的晃动及可变油膜系统实现中幅振动控制阶段的耗能，并通过控制中枢实时调节可变油膜系统的油膜厚度以实现半主动变阻尼控制；用磁流变阻尼器实现大幅振动控制阶段的耗能，并通过控制中枢实时调节磁流变阻尼器的通电量以实现半主动变阻尼控制，以及起到质量块的限位作用。
