[0050] The new tuned gas-liquid column damper in the present invention (such as figure 1 Shown), including the U-shaped tube 1, the damping valve 2 installed on the horizontal section of the U-shaped tube, which can adjust the damping force, the closed air column 4, 4'located in the vertical section of the U-shaped tube, and the corresponding pressure regulating device 5 ,5', and the movement liquid column 31.
[0051] The damping valve 2 that can adjust the damping force installed at the horizontal pipe section of the U-shaped pipe adopts a friction type damping valve, for example, a magnetorheological friction type damping valve or an electromagnet friction type damping valve. The damping valve 2 is connected to the damping valve through an external wire 12 The external power supply is connected, and the voltage / current of the external power supply can be changed to adjust the damping of the damper. The vertical pipe sections 3 and 3'are closed on the air columns 4 and 4', and ...
