Operating principle:
The multi-functional active controllable of the present invention shock insulation vibration absorber of exerting oneself greatly is made up of truncated cone type operational module and the antitorque operational module of disc type.The circular disk type thrust ball bearing carries truncated cone type operational module, and separates the relative displacement between truncated cone type operational module and the antitorque operational module of disc type; Inverted cone-shaped structure and the coaxial setting of fixed pressure ring huge pillar, variable cross-section center-pole position is reserved in both centres, the variable cross-section center-pole by with the key transmission of the anti-shearing magnetic conductive disk groove ends moment of torsion from truncated cone type operational module, the large deformation soft magnetic materials can be yielding permanent-magnet alloy or magnetically soft alloy, fixedlys connected with the variable cross-section center-pole with magnetic conduction matrix plate and does not reduce the whole permeability of truncated cone type operational module; Mainly exerting oneself of truncated cone type operational module comes from the inverted cone-shaped structure that is formed by magnetic rheology elastic body compounded magnetic conductive board helix-coil, inverted cone-shaped structure axially relatively back and forth distortion make between great circle and the ringlet and at vertical axial relative reciprocal torsional displacement arranged, the variable cross-section center-pole by and anti-shearing magnetic conductive disk between key reciprocal rotation is passed to anti-shearing magnetic conductive disk, the great circle of inverted cone-shaped structure and be limited in the relative displacement on the vertical axial between the ringlet between the pedestal pressing plate and reverse the elastic potential energy that is converted into the inverted cone-shaped structure light plate and the deformation energy of magnetic rheology elastic body.Resist the horizontal earthquake aspect, be equivalent to two vertical half laminated rubber bases of placing initiatively perpendicular to the alternate laminated structure of composite plate on the direction of motion, provide necessary level to rigidity.Magnetic rheology elastic body its stiffness and damping coefficient under the externally-applied magnetic field effect that controller provides changes with the magnetic field size variation, and then curling inverted cone-shaped structure its horizontal rigidity, vertical rigidity and the torsional stiffness under the excitation of circular excitation coil I that forms of the composite plate that makes magnetic rheology elastic body and permeability alloys steel plate form realizes non-linear controlled with outside dynamic load.Under general conventional dynamic load (building wind load, flooring dynamic load and vehicle generally the drive a vehicle vibrating load etc.) situation, magnetic induction intensity makes magnetic rheology elastic body have initial stiffness around the ring type permanent magnet I, together with cone-type spiral steel plate elastic deformation, make inverted cone-shaped structure have to resist the ability of low-level dynamic load; Under unconventional dynamic load (seismic load or vehicle jolt rough road driving vibrating load), circular excitation coil I is by the magnetic field of the variation output variation of controller input current intensity, regulate the mechanical property of magnetic rheology elastic body, guarantee permeability alloys steel plate is worked in elastic stage, makes inverted cone-shaped structure have stronger elastic restoring force.A orientation angle contact ball bearing, anti-shearing magnetic conductive disk and B location thrust ball bearing are in fixed pressure ring huge pillar and base seat groove; When anti-shearing magnetic conductive disk is subjected to variable cross-section center-pole moment of torsion and is rotated, if there is not magnetic field to pass through, the shear yield strength of magnetic flow liquid only is the null field viscosity of magnetic flow liquid, its value is very little, shearing magnetic conductive disk this moment can rotate because of the rotation of variable cross-section center-pole, and the antitorque operational module of disc type is exerted oneself very little;
