Anti-collision pendulum type tuned mass damper for wind vibration control of power transmission tower
The invention discloses an anti-collision pendulum type tuned mass damper for wind vibration control of a power transmission tower. The anti-collision pendulum type tuned mass damper comprises an L-plate-shaped clamp at the top, a steel rod, a mass block, a lug plate, a spring, a viscoelastic anti-collision pad, a spring fixing clamping plate and a spring L-plate clamp. The four top L plate clamps and the tower top angle steel are used for fixing and hanging the mass block. A lug plate is welded on the mass block, so that the mass block can be conveniently connected with a steel rod to form a unidirectional rotating hinge, one end of the spring is connected with a ring bolt of the spring L plate clamp, and the other end is connected with the mass block through a bolt; the viscoelastic anti-collision pads are distributed at the two ends of the tuning direction of the mass block, when the tower body shakes in the transverse line direction due to excitation of external wind loads and the like, the mass block swings opposite to the structure, energy is dissipated through the springs, displacement of the mass block is limited, vibration of the structure is controlled, and the purpose of collision prevention is achieved through the viscoelastic anti-collision pads.
本发明公开了一种用于输电塔风振控制的防撞击摆式调谐质量阻尼器，包括顶部的L板型夹具、钢杆、质量块、耳板、弹簧、粘弹性防撞垫、弹簧固定夹板、弹簧L板夹具；所述的顶部L板夹具共四个，与塔顶角钢来固定悬挂质量块；所述质量块焊有耳板，便于与钢杆连接形成单向转动的铰，所述弹簧一端与弹簧L板夹具的带环螺栓相连，另一端通过螺栓与质量块相连；所述的粘弹性防撞垫分布在质量块调谐方向的两端，当塔体因为外部风荷载等激励而产生横线方向的晃动时，质量块产生与结构相反的摆动，通过弹簧耗散能量和限制质量块位移，控制结构的振动，并通过粘弹性防撞垫达到防撞击的目的。
