Tuned inerter mass damper
The invention belongs to the technical field of vibration control, and discloses a tuning inerter mass damper which comprises an outer frame, an elastic device, an inerter damping device and a mass block. The mass block is suspended in the outer frame through the elastic device and the inerter damping device; the inerter damping device comprises a viscous damping unit, an inertia flywheel, a screw rod and a nut; the viscous damping unit comprises an outer cylinder connected with the outer frame and an inner roller rotationally arranged in the outer cylinder. A viscous material is arranged between the inner roller and the outer cylinder; the internal roller and the inertia flywheel are fixedly connected with the nut; the nut is in threaded connection with the lead screw, and one end of the lead screw is connected with the mass block. By adjusting the inerter coefficient, effective control over multi-order frequency vibration is achieved, the adjustable range is wide, the vibration damper is suitable for structural multi-frequency vibration control such as multi-order vortex vibration control of a suspension bridge, installation and maintenance are easy, the additional effect on the structure is small, and the vibration damping efficiency is high.
本发明属于振动控制技术领域，公开了一种调谐惯容质量阻尼器，包括外框架、弹性装置、惯容阻尼装置以及质量块；所述质量块通过弹性装置和惯容阻尼装置悬挂于外框架内；惯容阻尼装置包括粘滞阻尼单元、惯性飞轮、丝杆和螺母；粘滞阻尼单元包括与外框架连接的外部圆筒以及旋转式设置在外部圆筒内的内部滚筒；内部滚筒与外部圆筒之间设有粘性材料；内部滚筒和惯性飞轮均与螺母固定连接；螺母螺纹连接在丝杆上，丝杆的一端与质量块连接。本发明通过调节惯容系数，实现多阶频率振动的有效控制，且可调范围广，适于结构多频振动控制如悬索桥的多阶涡振控制，安装维护简单且对结构的附加效应较小，减振效率较高。
