The invention relates to a plate type viscosity damping device for an attached gear-type inertia unit which is used for civil engineering and energy infrastructures. The device comprises an upper connecting plate, a lower connecting plate, a gear-type inertia unit, outer steel plates, inner steel plates and high-viscosity liquid. Two sets of plate type viscosity energy dissipating units are composed of the outer steel plates, the inner steel plates and the high-viscosity liquid, the two sets of plate type viscosity energy dissipating units arranged on the two sides of the damper device are placed between the upper connecting plate and the lower connecting plate, and the inner steel plates and the outer steel plates are fixedly connected with the upper connecting plate and the lower connecting plate correspondingly to be whole bodies. The gear-type inertia unit is arranged between the two sets of plate type viscosity energy dissipating units. The device is composed of the plate type viscosity energy dissipating units and the gear-type inertia unit, vibration energy is absorbed by making full use of two node mass synergying units of the gear-type inertia unit, and the energy is dissipated by utilizing the plate type viscosity energy dissipating units. The damping device can effectively reduce the dynamic response of the structure, layer-to-layer displacement is controlled, and good application and popularization values are achieved.

technical field [0001] The invention belongs to the technical field of energy dissipation and shock absorption of civil engineering structures. Background technique [0002] Energy dissipation and vibration reduction technology is to add energy dissipation and vibration reduction devices to the structure. The additional vibration reduction devices and the structure itself bear the effects of earthquakes and wind vibrations. The dynamic response of the structure itself is reduced through the energy dissipation of the additional vibration reduction devices. Functional requirements such as safety, comfort and normal usability of the structure are guaranteed. The inertial shock absorber in the field is an acceleration-dependent energy dissipation shock absorber, and its inertial unit is a two-node unit with mass synergistic capability. The existing mass efficiency mechanism mainly uses ball screws and rotating nuts to convert the radial motion of the structure into high-speed r...

AI Technical Summary

Problems solved by technology

When the traditional viscous energy-dissipating unit has a relative displacement, the inner steel plate slides in the viscous material to generate a damping force proportional to the sliding velocity, but the energy dissipation capacity is often insufficient at low speeds.
