Abstract

The invention relates to a passive viscous damper which comprises a first damper and a second damper. The first damper and the second damper are oil cylinder type dampers. The first damper comprises a first oil cylinder connecting rod, a first piston rod and a first oil cylinder. The second damper comprises a second oil cylinder connecting rod, a second piston rod and a second oil cylinder. The first piston rod and the second piston rod are telescopic rod and are connected with a first structure. The first oil cylinder connecting rod and the second oil cylinder connecting rod are connected with a second structure. By adoption of the passive viscous damper, when the structures return to a balanced position, the first damper and the second damper generate a small damping force or do not generate the damping force, and a complex mechanical structure does not need to be adopted.

Description

technical field [0001] The patent of the invention relates to the anti-seismic field of bridges, buildings, water conservancy and other structures, in particular to a passive viscous damper. Background technique [0002] CN103335052B discloses a passive viscous damper with adjustable damping force. Based on the principle of Bang-Bang active control algorithm, the directional gear that can rotate counterclockwise and the directional gear that can rotate clockwise can only rotate in one direction. A mechanism consisting of a directional gear, a free gear, a rack track, a baffle, and a viscous damper is presented. When interstory displacement occurs in the structure, the process of returning to the equilibrium position is not hindered by the damping force of the viscous damper. This patent document proposes a design idea that "the damping force of the damper is an unfavorable factor for the structure when the structure returns to the equilibrium position, and a design idea is ...
