A two-way damping hinge device and damping method

Abstract

The invention discloses a two-way damping hinge device, which includes an X-axis damping mechanism and a Y-axis damping mechanism; the X-axis damping mechanism includes a lower connecting support and an X hinge shaft; the lower connecting support is provided with an X-pinion rack transmission mechanism, XU-type transmission crank and X roller; Y-axis damping mechanism includes upper connecting support and Y hinge; Y-pinion and rack transmission mechanism, YU-type transmission crank and Y roller are arranged on the upper connecting support; Y driving gear and Y hinge The Y hinge shaft is fixedly connected, the Y driven rack is fixedly connected with the YU-type transmission crank; the X driving gear is fixedly connected with the X hinge shaft, and the X driven rack is fixedly connected with the XU-type transmission crank; the Y hinge is connected with the X hinge The axis is fixed and vertical. In addition, the invention also provides a damping method of the bidirectional damping hinge device. The device can be applied to a spatial structure that produces rotational displacement in two directions, effectively avoids rigid fixation of the two rotational directions during the vibration process, and avoids the impact on the structure due to excessive stiffness difference.

Description

technical field [0001] The invention belongs to the technical field of anti-seismic and shock-absorbing technology of civil engineering, and in particular relates to a two-way damping hinge device and a damping method. 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 technology includes the application of various en...

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

[0003] For the unique structural characteristics such as large-span spatial structures, the vibration process will produce rotational displacement in two directions. It is often used in the connection between structural frame beams and frame columns, or in the connection between structural frame beams and shear walls, etc. Only one direction is allowed. The one-way hinge device of the project where the rotation displacement occurs cannot meet the rotation requirements in the other direction, that is, a rigid fixed support is formed in the other direction, resulting in a large difference in the overall stiffness of the structure in the two perpendicular directions of the plane. For the structure detrimental effect on the overall vibration control of the
