One-way damping hinge device and method for controlling passive vibration of structure by using same

Abstract

The invention discloses a one-way damping hinge device, which comprises an upper connecting support, a lower connecting support and a hinge shaft, wherein the hinge shaft is fixedly connected with theupper connecting support; the hinge shaft is rotatably connected with the lower connecting support; a gear rack transmission mechanism, a damper mounting frame and a U-shaped transmission curved rodwhich is fixedly connected with an input rod of a damper are arranged on the lower connecting support; the gear rack transmission mechanism comprises a driving gear and a driven gear rack which are meshed with each other; the driving gear is fixedly connected with the hinge shaft; the driven gear rack is fixedly connected with the U-shaped transmission curved rod; and rollers are arranged betweenthe damper mounting frame and the U-shaped transmission curved rod. In addition, the invention also provides a method for controlling passive vibration of a structure by using the one-way damping hinge device. According to the one-way damping hinge device, the gear transmission principle is utilized, so that the capability of the building structure to resist vibration load can be effectively improved, the vibration control efficiency of the building structure is improved, and a new and effective method is provided for the vibration control of the structure in the field of civil engineering.

Description

technical field [0001] The invention belongs to the field of anti-seismic and shock-absorbing technology of civil engineering, and in particular relates to a one-way damping hinge device and a method for controlling passive vibration of structures by using the same. Background technique [0002] In order to meet the needs of social life, the current buildings show a trend of increasing height, increasing span, and increasingly complex structural forms. Structural design based on traditional design methods, especially engineering structures under dynamic loads such as earthquakes design, it is difficult to meet the requirements. In order to prevent the dynamic response of the structure and further improve the safety of the structure, people usually use vibration control technology. Currently commonly used vibration control technologies include passive anti-seismic control technology and passive energy consumption control technology. Among them, passive anti-seismic control t...

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
