Intelligent wire rope vibration isolator

Abstract

The invention discloses an intelligent wire rope vibration isolator which comprises an upper end plate, a lower end plate, a wire rope and a working cylinder, wherein the upper end plate and the lower end plate are oppositely arranged; the wire rope is arranged between the upper end plate and the lower end plate; the working cylinder is arranged between the upper end plate and the lower end plate; a big cavity and a small cavity of the working cylinder are communicated with each other; a magnetorheological fluid is filled in the working cylinder; a coil is wound on the outer surface of the working cylinder; an upper acceleration sensor and a lower acceleration sensor are respectively arranged on the upper end plate and the lower end plate; the intelligent wire rope vibration isolator further comprises a signal wire and a single chip microcomputer controller which is connected with the coil and the acceleration sensors. According to the intelligent wire rope vibration isolator, the magnetic field intensity in the working cylinder can be changed by quickly changing the current according to the change of the outside load, so that the damping of the wire rope vibration isolator is changed and the vibration-isolating property of the wire rope vibration isolator is effectively increased. The intelligent wire rope vibration isolator is simple in structure and small in volume.

Description

Technical field [0001] The invention relates to an intelligent steel wire rope vibration isolator, in particular to an intelligent steel wire rope vibration isolator of magnetorheological technology, which reduces the impact of external environment on equipment impact vibration and belongs to the technical field of vibration and noise reduction. Background technique [0002] The wire rope vibration isolator is a new type of passive vibration isolator that appeared in the 1970s. It is made up of springs twisted by multiple strands of stainless steel wire around the upper and lower support plates. The support plates have mounting holes that can slow down any direction Vibration and shock. It has the advantages of large deformation softening, broadband vibration isolation, high damping ratio, large vibration space, corrosion resistance, high and low temperature resistance, etc. The equivalent stiffness of the vibration isolator spring decreases rapidly with the increase of deformati...
