An inner-wound magneto-rheological damper with multi-legged parallel propulsion

Abstract

The invention discloses a multi-legged parallel-connection propellent inner winding type magnetorheological damper. The damper comprises a damper cylinder barrel, a piston head arranged in the dampercylinder barrel and a shock absorption damping mechanism connected with the piston head; the left end and the right end of the damper cylinder barrel are in clearance fit connection with a damper leftend cover and a damper right end cover correspondingly through screws, and sealing is achieved through a seal ring; the piston head is arranged in the damper cylinder barrel in a sliding manner, thepiston head is in fastened connection with a piston rod through a locking nut, a winding groove is machined in the piston head, a magnet exciting coil is wound in the winding groove of the piston head, and the right side of the piston head is connected with the shock absorption damping mechanism. The shock absorption damping mechanism in the inner winding type magnetorheological damper is combinedwith the magnetorheological damper, the structure is compact, the size is small, the damper can conveniently work on the occasion with the narrow and small space, and needs a small amount of magnetorheological fluid with high price, and the manufacturing cost of a vibration absorbing device is reduced.

Description

technical field [0001] The invention relates to a magneto-rheological damper, more specifically, it relates to an inner-winding magneto-rheological damper propelled by multiple legs in parallel. Background technique [0002] The magnetorheological damper is a new type of semi-active damping device based on the controllable characteristics of magnetorheological fluid. The damping device can generate resistance to movement and be used to dissipate the energy of movement; It has the advantages of simple structure, small size, easy control and low energy consumption; it is an ideal vibration isolation and anti-seismic device; it has wide application prospects in construction, machinery, military industry, etc. [0003] The traditional spring damper is used in various vibration reduction occasions, but as people's requirements for vibration reduction effect are getting higher and higher, the vibration reduction effect played by the spring damper is gradually unsatisfactory. The ...

AI Technical Summary

Problems solved by technology

[0004] In the existing semi-active vibration reduction system based on the magnetorheological damper, since the viscosity of the magnetorheological fluid in the absence of a magnetic field is higher than that of ordinary hydraulic oil, even in the case of no current input, the magnetorheological damping The device also exerts a harder damping force and is less sensitive to vibration

At the same time, magnetorheological fluid is more expensive than ordinary hydraulic oil, which increases the manufacturing cost of magnetorheological damper
