A Device for Improving Synchronization of Viscous Damper

Abstract

The present invention proposes a device for improving the synchronization of viscous dampers, which includes several viscous dampers, the viscous dampers include a cylinder filled with damping medium, and a piston device inserted on the cylinder, The piston device moves in the cylinder, and the damping medium in the cylinder provides a certain damping force to the piston device when moving; the pressure transmission device connected to the viscous damper, the transmission The cylinders of each viscous damper in the pressure device are connected; wherein, the damping media in different viscous dampers communicate with each other through the pressure transmission device, thereby balancing the pressure in different cylinders and synchronizing the piston devices move. The invention adopts the method of connecting pressure chambers on the same side of a plurality of viscous dampers, so that the internal pressure of the plurality of viscous dampers can be kept consistent when working at the same time, so as to achieve the purpose of ensuring the balanced force of the structure.

Description

technical field [0001] The invention relates to a device for improving the synchronism of a viscous damper, which belongs to the field of viscous dampers. Background technique [0002] The viscous damper is an energy-dissipating shock-absorbing device, which has the characteristics of strong energy-dissipating capacity and large stroke, and is widely used in structural shock-absorbing fields such as long-span bridges and high-rise buildings. [0003] The basic working principle of the viscous damper is to squeeze the damping medium through the piston, so that it flows through the flow channel in the cylinder body at high speed, and energy loss occurs during the flow process, and the kinetic energy of the outside world is converted into heat energy of the damping medium, thereby reducing earthquakes. , strong wind and other external forces damage to the structure. With the gradual improvement of national seismic fortification requirements, the tonnage of viscous dampers is a...

AI Technical Summary

Problems solved by technology

With the gradual improvement of national seismic fortification requirements, the tonnage of viscous dampers is also gradually increasing, but a single large-tonnage viscous damper has problems such as limited installation space and difficult tests.

At present, in some areas, a single large-tonnage viscous damper has been split into multiple small-tonnage viscous dampers to solve the above problems. The output force, displacement, and response speed of a viscous damper are difficult to keep consistent, which will have adverse effects on the structure such as additional moment, deflection, etc.
