Serially connected viscosity mass damping device
The invention relates to a serially connected viscosity mass damping device, which is used for energy consumption earthquake (vibration) reduction and isolation of house building structure and bridge engineering. The damping device comprises a ball screw, a rotating mass, a ball screw nut, viscosity liquid, an outer tube, an inner tube, an ear ring and a ball bearing, wherein at the left side of the device, the ball screw and the ball screw nut are connected into a whole through welding; the ball screw sequentially passes through the ball screw nut and the rotating mass and achieves mutual restriction with the ball screw nut through screw threads; at the right side of the device, the inner tube and the ball screw nut are connected into a whole through welding; the ball screw sequentially passes through the ball screw nut and the right end of the inner tube and achieves mutual restriction with the ball screw nut through screw threads; and a position between the inner tube and the outer tube is filled with the viscosity liquid. A mass damper is connected in series with a viscosity damper; the effects of the mass damper and a nonlinear viscosity damper can be achieved at the same time; the viscosity damping synergistic effect and the mass synergistic effect are achieved through the ball screw; and the energy dissipation performance is good.
