Problems solved by technology

[0006] At present, the starting force required by the rotating friction damper is relatively large, which is equivalent to a connected rigid body before starting; the output force and energy consumption of the damper are constant after starting, and cannot adapt to applications where the external force changes greatly

Abstract

The invention discloses a frictional energy dissipation damper which comprises a moving flat plate device and auxiliary clamping devices. The frictional energy dissipation damper is characterized in that the damper also comprises face gears, a horizontal plate group and a longitudinal plate group of the moving flat plate device are mutually connected; the face gears are arranged in pairs at the connection portions of the horizontal plate group and the longitudinal plate group, and the tooth surfaces of the face gears are in contact with each other and complementary; the auxiliary clamping devices are located at the upper portion and the lower portion of a face gear adjusting device. The damper has low starting power, and after starting, the generated damping force and energy dissipation capability can be adjusted according to the degree of deformation of the damper.

Description

technical field [0001] The invention relates to the technical field of vibration reduction of buildings and mechanical structures, in particular to a frictional energy-dissipating damper. Background technique [0002] Energy-dissipating shock-absorbing devices are an important aspect of modern building anti-seismic devices. By setting energy-dissipating dampers in the building structure to consume earthquake energy, reduce the damage of the main structure of the building, so as to achieve the purpose of anti-seismic. Rotational friction damper is a kind of energy dissipation friction damper. The mechanism of the vibration control of the structure by the rotational friction damper is: the structure undergoes lateral deformation under the action of the earthquake load, and the damper installed in the structure deforms accordingly, and the translational deformation is converted into the internal rotation of the damper mechanism, relying on The friction generated by the rotatio...
