Abstract

The invention relates to a sleeved viscous damper capable of damping variable parameters and a design method thereof. The sleeved viscous damper capable of damping variable parameters comprises a cylinder body of which two ends are sealed by end covers and in which a damping medium is filled, an axial clearance-free piston positioned in the cylinder body, a piston guide rod connected with the axial clearance-free piston, and a sleeved piece with a damping hole and a sleeved piece without a damping hole which are arranged in a sleeved mounting hole, wherein the axial end face of the axial clearance-free piston is provided with the sleeved mounting hole; and the axis of the sleeved piece with the damping hole is provided with a damping hole. The design method comprises the following steps of: determining a sleeved piece combination with the damping hole; mounting or replacing the sleeved piece with the damping hole; sealing the sleeved mounting hole which is not used; and finishing design of the variable parameters. The sleeved viscous damper is simple in structure and method and rapid in design. According to the method, a pore type viscous damper is developed and machined and is subjected to experimental operation, the efficiency can be improved, the material cost is reduced, and the economic benefits and social benefits are obvious.

Description

[0001] technical field [0002] 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 plug-type viscous damper capable of realizing variable damping parameters and a design method thereof. Background technique [0003] 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 ...
