Single-side magneto rheological intelligent anti-vibration pad

Abstract

The 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 fixed on the electromagnet array board. 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 upper bottom of each orthohexagonal lattice is sealed by macromolecular elastic / flexible material, 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 having a diameter less than that of an inscribed circle of an orthohexagonal lattice on the magneto rheological flat pad; 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 [0001] The invention belongs to a vibration damping pad, in particular to a single-sided magnetorheological intelligent vibration damping pad. Background technique [0002] Ordinary vibration damping pads are made of rubber or polymer elastic materials. This type of vibration damping pad mainly changes the vibration damping performance of the vibration damping pad by changing the structural shape of the vibration damping pad or adding different materials to its surface and inside. Such as: two kinds of damping pads disclosed in Chinese patent 200820183414.2 and Chinese patent 200620148742. Afterwards, its damping performance has been fixed and cannot be changed. Therefore, it is difficult for this type of damping pad to meet the different requirements of different vibration damping occasions for the performance of the damping pad. Contents of the invention [0003] The present invention aims at the problem that the vibration-damping performance of ordinary...
