One-way damping hinge device and its application for passive vibration control of structures

Abstract

The invention discloses a one-way damping hinge device, which comprises an upper connection support, a lower connection support and a hinge shaft, the hinge shaft is fixedly connected with the upper connection support, and the hinge shaft is rotatably connected with the lower connection support; There is a rack and pinion transmission mechanism, a damper mounting frame and a U-shaped transmission crank fixedly connected with the input rod of the damper. The rack and pinion transmission mechanism includes a driving gear and a driven rack that mesh with each other, and the driving gear is fixed to the hinge shaft. connection, the driven rack is fixedly connected with the U-shaped transmission crank; a roller is arranged between the damper mounting frame and the U-shaped transmission crank. In addition, the invention also provides a method for passive vibration control of structures using the one-way damping hinge device. The one-way damping hinge device of the present invention utilizes the principle of gear transmission, which can effectively improve the ability of the building structure itself to resist vibration loads, improve the vibration control efficiency of the building structure, and provide a new and effective method for the vibration control of structures in the field of civil engineering.

Description

Technical field [0001] The invention belongs to the technical field of earthquake resistance and damping in civil engineering, and in particular relates to a one-way damping hinge device and a method for applying the same for passive structural vibration control. Background technique [0002] In order to meet the needs of social life, the current buildings are showing a trend of increasing height, increasing span, and increasingly complex structural forms. Structural design is carried out according to traditional design methods, especially engineering structures under dynamic loads such as earthquakes. The design is difficult to meet the requirements. In order to prevent the structure from generating dynamic response and further improve the safety of the structure, people usually adopt vibration control technology. Currently commonly used vibration control technologies include passive seismic control technology and passive energy consumption control technology. Among them, passi...

Problems solved by technology

However, there are few related studies on replacing the rigid joints between components with damping devices to improve the seismic capacity of the structure itself. In the prior art, it is difficult to integrate damping devices with different types of structures or components, and The maintenance and repair guarantee of the damping device is relatively difficult, which limits the scope of use of the damping device between components

The damping devices in the prior art are mostly mild steel dampers, which consume the vibration energy input into the structure through buckling damage, and the buckling damage also affects the performance parameters of the mild steel damper itself, resulting in soft The steel damper will no longer be able to protect the structure from vibration in a short period of time, and the reliability will be greatly reduced
