Embodiment 1
[0034] A vibration reduction control device for a tuned mass damper, comprising a support frame 1, a mass block 3 and a damping element 5, the mass block is suspended under the support frame through a swing rope 4, one end of the swing rope is connected to the mass block, and the other end is connected to the support frame beam 11 Tension springs 2 are evenly distributed between the outer periphery of the mass block 3 and the support frame, and the tension spring is arranged horizontally, one end of which is connected to the support frame (a column or frame that can be connected to the support frame), and the other end is connected to the mass Block connection, the damping element is set between the bottom of the mass block and the bottom plate of the support frame; the mass block is composed of multiple steel plates (the number of blocks can be increased or decreased to adjust the frequency), the overall structural shape is a cube, and 4 tension springs Evenly distributed on t...
Embodiment 2
[0038] A tuned mass damper vibration reduction control device, its structure is basically the same as that of Embodiment 1, including a support frame 1, a mass block 3 and a damping element 5, and the mass block is suspended under the support frame by a pendulum rope 4; the mass block 3 Tension springs 2 are evenly distributed between the outer periphery and the support frame. The tension springs are arranged horizontally. One end of the tension spring is connected to the support frame, and the other end is connected to the mass block. The damping element is arranged at the bottom of the mass block and the bottom plate of the support frame. Between; the mass block is made up of multiple steel plates, the overall structural shape is a cube, the pendulum rope is four steel wire ropes, the support frame is a square support frame, and the pendulum length adjusting part 6 is installed on the support frame, so The pendulum length adjusting part is a square frame, the four corners of ...
Embodiment 3
[0041] A tuned mass damper vibration reduction control device, its structure is basically the same as that of Embodiment 1, including a support frame 1, a mass block 3 and a damping element 5, and the mass block is suspended under the support frame by a pendulum rope 4; the mass block 3 Tension springs 2 are evenly distributed between the outer periphery and the support frame. The tension springs are arranged horizontally. One end of the tension spring is connected to the support frame, and the other end is connected to the mass block. The damping element is arranged at the bottom of the mass block and the bottom plate of the support frame. between; the mass block is made up of multiple steel plates, the pendulum rope is 4 steel wire ropes, and the pendulum length adjustment part 6 is installed on the support frame, and the pendulum length adjustment part is a square frame, and the four corners of the frame are connected with the support frame The columns are slidably connected...
