Novel intelligent damping base based on magnetorheological damper

Abstract

A sliding seat is movably connected to the inner wall of a mounting cylinder fixedly connected to the top of a first mounting plate, a second mounting plate is fixedly connected to the top of the sliding seat, a fixing cylinder is fixedly connected to the inner wall of the bottom of the mounting cylinder, and a first connecting rod is movably connected into a third sliding groove in the top of the fixing cylinder; a piston is fixedly connected to the bottom end of the first connecting rod, an inserting groove is formed in the bottom of the first connecting rod, a positioning steel ball is fixedly connected into the inserting groove, a spiral groove is formed in the outer side of the circumference, movably connected with a rotating rod, of the inner wall of the bottom of the fixing cylinder and makes contact with the positioning steel ball, and a plurality of high-toughness plates are fixedly connected to the bottom end of the rotating rod. An electromagnetic coil is fixedly connected in an inner cavity of the fixed cylinder; the damping base with the magnetorheological damper solves the problems that the damping adjusting effect of the magnetorheological fluid is poor and the damping buffering effect of the damping base with the magnetorheological damper is affected due to the fact that the magnetorheological fluid in an existing magnetorheological damper is precipitated after standing for a long time.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, and relates to a novel intelligent shock absorber base based on a magneto-rheological damper. Background technique [0002] Vibration can cause a series of problems, such as the fracture and failure of mechanical parts caused by vibration, the fracture and collapse of bridges, and the deterioration of the working environment of workers. A variety of shock absorbers have been used to reduce vibration and energy dissipation in China. Passive shock absorbers composed of springs with fixed stiffness and dampers with fixed damping have become the main form of vibration reduction in the field of vibration reduction. With the improvement of vibration requirements, passive shock absorbers can no longer meet people's needs, especially for some high-demand vibration reduction fields, it is more and more urgent to develop a new type of high-efficiency shock absorber.

Problems solved by technology

[0004] In view of this, the present invention solves the phenomenon that the magnetorheological fluid in the existing magnetorheological damper will precipitate when it is left standing for a long time, resulting in the poor effect of the magnetorheological fluid in adjusting damping, which affects the magnetorheological damper with magnetorheological damper. The problem of the shock absorption and buffering effect of the shock-absorbing base is to provide a new type of intelligent shock-absorbing base based on the magneto-rheological damper
