Abstract
The present invention discloses a single-side magneto rheological intelligent anti-vibration pad, consisting of a magneto rheological flat pad and an electromagnet array board, wherein the magneto rheological flat pad is made from macromolecular elastic material, and is in the shape of N orthohexagonal lattices which are arranged in a honeycomb, having certain thickness; the internal surface or external surface of the macromolecular elastic/flexible material that seals the upper bottom is bound with a circular soft iron plate; a lower bottom of each orthohexagonal lattice is sealed by macromolecular elastic/flexible material, and the cavities of the N orthohexagonal lattices which are formed by sealing the upper bottom and the lower bottom are filled with magneto rheological fluid. The electromagnet array board consists of N pot-shaped electromagnets having a diameter smaller than or equal to that of an inscribed circle of an orthohexagonal lattice on the magneto rheological flat pad. The electromagnetic field intensity at the upper end of each pot-shaped electromagnet is varied by changing the current passing through each pot-shaped electromagnet on the electromagnet array board, so that the rigidity of the magneto rheological flat pad fixed on the electromagnet array board is changed, and then the purpose of anti-vibration is achieved.
Description
Technical field
The invention belongs to a kind of damping pad, be specifically related to a kind of single-side magneto rheological intelligent anti-vibration pad.
Background technique
Common damping pad adopts rubber or macromolecular material to constitute, this class damping pad mainly is by the structure shape that changes damping pad or changes the damping property of damping pad in methods such as its surface and inner additional different materials, as: the disclosed two kinds of vibration attenuation pads of Chinese patent 200820183414.2 and Chinese patent 200620148742.X, although they all have certain damping property, also can be applicable to some vibration damping occasions, but owing in case its damping property after this class damping pad production moulding is just fixing and immutable, therefore, this class damping pad is difficult to satisfy the different requirements of different vibration damping occasions to the damping pad performance.
Summary of the invention
The present invention is directed to the unmodifiable deficiency of its damping property after the common damping pad machine shaping, a kind of single-side magneto rheological intelligent anti-vibration pad has been proposed, the damping property of single-side magneto rheological intelligent anti-vibration pad not only can change by the electric current that changes by single-side magneto rheological intelligent anti-vibration pad, but also can realize different damping properties in the zones of different on the single-side magneto rheological intelligent anti-vibration pad.
Technological scheme of the present invention is as follows:
Single-side magneto rheological intelligent anti-vibration pad is made of magnetorheological plain cushion and electromagnet array board, and magnetorheological plain cushion is fixed on the electromagnet array board; Wherein, magnetorheological plain cushion is N the regular hexagon space that has certain thickness to become the honeycomb shape to arrange that is made of macromolecular material, the upper base in each regular hexagon space adopts high polymer elastic or flexible material sealing, the internal surface of sealing high polymer elastic of upper base or flexibility material or the bonding diameter of outer surface less than magnetorheological plain cushion on the circular soft iron plate of regular hexagon space inscribed circle, high polymer elastic or flexible material sealing are adopted in going to the bottom of each regular hexagon space, all have been full of magnetic flow liquid in N the regular hexagon cavity that forms after underseal closes up and down; And the electromagnet array board is made of the jar shape electromagnet that N diameter is less than or equal to regular hexagon space inscribed circle on the magnetorheological plain cushion, jar shape electromagnet is to be that the core of mountain font jar shape soft iron is wound with electromagnetic coil and constitutes in the cross section, N jar of shape electromagnet arranged the back that is shaped and adopted non-magnet material to cast the flat board of surfacing, the bottom surface of each the regular hexagon cavity on the electromagnet array board on the top of each jar shape electromagnet and the magnetorheological plain cushion is corresponding, and concentric with the inscribed circle of regular hexagon cavity bottom surface.
Function of the present invention is achieved in that
Each jar shape electromagnet on the electromagnet array board of single-side magneto rheological intelligent anti-vibration pad is a damper unit with a regular hexagon cavity that has been full of magnetic flow liquid on its corresponding magnetorheological plain cushion in upper end; Because of magnetic flow liquid is a kind of novel intelligent material, under the action of a magnetic field, continuous variation can take place in its viscosity, therefore, when jar shape electromagnet feeds different electric currents, to produce the electromagnetic field of varying strength in the upper end of jar shape electromagnet, this electromagnetic field sees through magnetorheological plain cushion and goes to the bottom, the bonding circular soft iron plate of magnetic flow liquid in the regular hexagon cavity and magnetorheological plain cushion upper base internal surface or outer surface forms closed magnetic circuit, this closed magnetic circuit makes the magnetic flow liquid that is in the regular hexagon cavity have different viscosity, makes regular hexagon cavity on jar magnetorheological plain cushion of shape electromagnet upper end have different rigidity and reaches the purpose of vibration damping.Because a single-side magneto rheological intelligent anti-vibration pad is made of N such damper unit, if each damper unit is considered as " point " on the single-side magneto rheological intelligent anti-vibration pad, then the damping property of each " point " all can independent regulation on the single-side magneto rheological intelligent anti-vibration pad.Therefore, compare with the damping pad that adopts common rubber or macromolecular material to constitute and since on the single-side magneto rheological intelligent anti-vibration pad each " point " but the equal independent regulation and applicable scope is wider of damping property.
