Abstract

The invention relates to a design and assembly method of a plug-type viscous damper capable of realizing variable damping parameters. The plug-type viscous damper that can realize variable damping parameters includes: a cylinder body sealed with end caps at both ends and filled with damping medium; Plug mounting hole; piston guide rod connected to the piston without axial clearance; plug with damping hole and plug without damping hole installed in the plug mounting hole, the shaft center of the plug with damping hole is provided with damping hole. The design method includes: determining the combination of plugs with damping holes; installing or replacing plugs with damping holes; sealing unused plug installation holes; and designing after changing parameters. The structure and method of the invention are simple, and the design is fast. According to this method, the development, processing and experiment work of the pore-type viscous damper can greatly improve the efficiency and reduce the material cost, and its economic and social benefits are very significant.

Description

technical field [0001] The patent of the present invention relates to the field of energy dissipation and vibration reduction (seismic) control of civil engineering structures, and more specifically, relates to a design and assembly method of a plug-type viscous damper that can realize variable damping parameters. Background technique [0002] Earthquake and wind disasters seriously threaten the survival and development of human beings. Since the birth of human beings, people have been fighting against these two natural disasters. With the improvement of science and technology and people's living standards, the ability to prevent and resist earthquakes and wind disasters is also constantly improving. As an effective method of resisting earthquakes or strong winds, structural vibration reduction (seismic) control technology has also been developed and applied. , and has become a relatively mature technology. The structural vibration reduction (seismic) control method has chan...
