Frequency-adjustable vertical tuned mass damper

The invention discloses a vertical tuned mass damper with adjustable frequency, which comprises a mounting frame and a mass block, a spiral spring, a damping device and a spring steel sheet are fixedly connected between the mounting frame and the mass block, the spiral spring and the damping device are vertically arranged, the spring steel sheet is horizontally arranged, and the damping device is fixedly connected with the mounting frame. And the spring steel sheet is detachably connected with the mounting frame and the mass block. The spring steel sheet is of a sheet-shaped structure made of spring steel, and when the spring steel sheet is horizontally arranged, the spring steel sheet has the elastic deformation capacity in the vertical direction. The frequency is tuned and controlled by adjusting the number and the size of the spring steel sheets, and compared with direct adjustment and replacement of spiral springs, the replacement operation is simpler, and the adjustment precision is better; the horizonta
