Abstract

The invention belongs to engineering structure damping devices, and particularly relates to an adjustable viscous damper. The adjustable viscous damper is technically characterized by comprising a cylinder body and a piston rod, wherein the piston rod comprises an inner piston rod and an outer piston rod, the inner piston rod is mounted in the outer piston rod, symmetric internal damping holes are formed in the wall of a round hole in the lower end of the inner piston rod, and symmetric outer damping holes are formed in the corresponding position of the hole wall of the outer piston rod; an external thread is formed in the upper part of the inner piston rod, an adjusting nut is arranged in the corresponding position of the outer piston rod, the outer piston rod is controlled to longitudinally move relative to the inner piston rod by rotating the adjusting bolt, so that the outer damping holes and the inner damping holes are mutually aligned or staggered. During a use process, the adjustable viscous damper can adjust damping to adapt to different structures and loads, thereby effectively restraining structural vibration response.

Description

technical field [0001] The invention belongs to an engineering structure damping device, and in particular relates to an adjustable viscous damper which can adjust the damping size during use to adapt to different structures and loads, so as to more effectively restrain the vibration response of the structure. Background technique [0002] Since people introduced viscous dampers into structural engineering such as buildings, bridges and railways in the 1970s, after more than 30 years of development, the structural engineering field abroad has already possessed a considerable scale. Among them, the viscous damper designed and produced by Taylor Company of the United States has appeared in the teaching materials of various structural shock absorption as a standard. [0003] The research on dampers first started in military enterprises in some developed countries. Due to the influence of policies of various countries, most of the design and application data of dampers are not m...
