The invention discloses an intelligent phonon crystal vibration isolator based on magentorheological plastomers, and relates to the technical field of seismic isolation and vibration reduction. The intelligent phonon crystal vibration isolator comprises an upper cover plate, an lower cover plate, a magnetic conduction magnetic steel column core, magnetic conduction supporting inner ring columns, magnetic conduction supporting outer ring columns, coils, a magnetic isolation copper column, magnetic isolation ring columns, magnetic isolation sleeves, bolts, an upper supporting plate, a lower supporting plate and magnetic isolation gaskets; and magentorheological plastomers and working magnetic steel cylinders are arranged at intervals to form phonon crystals with an one-dimensional horizontal phonon crystal structure, and a magnetic field closed loop is defined by the magnetic conduction magnetic steel column core, the one-dimensional horizontal phonon crystal structures, the magnetic conduction supporting inner ring columns, the upper cover plate, the magnetic conduction supporting outer ring columns and the lower cover plate together. According to the intelligent phonon crystal vibration isolator based on the magentorheological plastomers, the more effective seismic isolation and vibration reduction can be carried out on civil engineering or mechanical engineering industry whenencountering the vibration excitation, the one-dimensional horizontal phonon crystal structure mode is introduced on the basis of the magentorheological plastomers, the magentorheological plastomershave an adjustable rheological property under the action of a magnetic field, and so that intelligent blocking on the vibration excitation is achieved.

Description

technical field [0001] The invention mainly relates to the technical field of structural shock isolation and vibration reduction, and relates to a one-dimensional horizontal intelligent phononic crystal shock isolator based on a magnetorheological plastic body for blocking vibration. Background technique [0002] In order to resist earthquake damage, the traditional anti-seismic technology of buildings is achieved by increasing the cross-sectional size of beams and columns, increasing the reinforcement of beams and columns, and improving the strength of building materials. The stronger the seismic action transmitted to the upper structure, the result. However, the building isolation technology of "using softness to overcome rigidity" is different from the traditional anti-seismic technology. At present, the most commonly used in engineering is the laminated rubber bearing isolation system between the foundation and the superstructure, and setting special rubber isolation bea...
