Abstract

The invention discloses a semi-active magneto-rheological intelligent tuning damping device. The device comprises a cylinder body, wherein a mass block is arranged in the center of the cylinder body,work cylinders are arranged in the left, rear, left and right directions in the cylinder body respectively, and the mass block is connected with the front and rear work cylinders or the left and rightwork cylinder through rigid rods respectively; each work cylinder is divided into three independent cavities by partition plates, wherein the middle cavity is a damping cavity, and the cavities at the two sides are side cavities; the side cavities are internally provided with springs connecting the corresponding work cylinder the corresponding partition plates, each damping cavity is filled witha magneto-rheological liquid, each damping cavity is internally provided with a piston, the two ends of each piston are connected with piston rods respectively, each piston rod penetrates through thecorresponding side cavity and is connected with a sliding block, and the two adjacent piston rods of the corresponding adjacent work cylinders are connected with a same sliding block; the sliding blocks are arranged on sliding rails; an energized coil winds each piston, and each energized coil is connected to an induction control device.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a semi-active magneto-rheological intelligent tuning vibration damping device, which is mainly used for vibration damping control of large-span, towering and other related structures. Background technique [0002] With the development of society and economy, the form of architectural structure tends to be diversified and complicated, and the sensitivity to wind, rain or earthquake disasters is also becoming more and more significant. Under the action of wind load or earthquake, the building structure produces a strong vibration response, and the structural components are fatigued and damaged to varying degrees. Once they fail, continuous damage will occur, resulting in serious partial or overall collapse of the building structure. Vibration control technology is an effective method to reduce structural vibration. At present, according to the degree of external energy input, it ...
