Problems solved by technology

[0009] However, for the frame structure and frame-shear wall structure, the interstory displacement of the top and upper floors is relatively small, and if dampers are arranged on these floors, the energy dissipation effect is not ideal
In particular, in some structures, the displacement between each story is small, and the damping effect of the viscous damper will be very limited at this time

Abstract

The invention discloses a rotation amplifying power output device of a viscous damper. The rotation amplifying power output device of the viscous damper comprises the viscous fluid damper which is provided with an outer cylinder and a guiding rod. The rotation amplifying power output device of the viscous damper is characterized by further comprising a fixed seat and a rotation plate. An arc track and a linear guide rail are arranged in the fixed seat. The rotation plate is connected with the fixed seat and rotates on the arc track with the center of the arc track as a fulcrum. A guiding groove is formed in the rotation plate. The outer cylinder of the viscous fluid damper is located in the guiding groove and fixed with a sliding block. The guiding rod of the viscous fluid damper is fixed with the fixed seat. The sliding block is arranged on the linear guide rail. The device is low in manufacturing cost and superior in performance, solves the problem that the viscous fluid damper is arranged on a floor with little story drift, obviously amplifies damping force and improves the energy consumption efficiency of the damper.

Description

technical field [0001] The invention relates to a damping force amplifying device of a viscous damper, which is especially suitable for use in large-scale civil engineering structures in earthquake-prone areas, so as to effectively control the seismic response of the structure and reduce earthquake disasters, and can also be used to lower the structure Wind vibration response. Background technique [0002] Earthquake is a sudden natural disaster that endangers people's life and property, and has caused very heavy loss of life and property in the world. my country is one of the earthquake-prone countries in the world. For example, the Tangshan earthquake in Hebei Province on July 28, 1976 had a magnitude of 7.8 and killed more than 240,000 people. Houses, industrial plants and equipment, urban construction, transportation, and hydropower facilities in the strong earthquake area were severely damaged. destroy. The 8.0-magnitude earthquake in Wenchuan, Sichuan Province on May...
