Description
Technical field
The utility model is related to a kind of vibration isolators；More particularly to a kind of magnetorheological elasticity based on shearing-tension and compression pattern
Body vibration isolator.
Background technology
Magnetic rheology elastic body is a kind of novel intelligent material, and mechanical property and electric property can be with the changes of external magnetic field
Change and change, and to the response quickly in magnetic field, continuous, reversible, intelligent mechanism, vibration damping are widely used in based on its good characteristic
The fields such as shock-absorbing and sensor.MR elastomer vibration isolator is mainly the magnetic effect using elastomer, and then changes its bullet
Property modulus, realizes its effect.
For MR elastomer vibration isolator, that generally there are elastic modulus changes is smaller in existing technology, and vibration isolating effect is not
Phenomena such as ideal, stability is poor, cannot be satisfied actual needs.
Invention content
The utility model in view of the foregoing drawbacks, provides a kind of easy to operate, simple in structure, effective based on cutting
Cut-the MR elastomer vibration isolator of tension and compression pattern.
A kind of MR elastomer vibration isolator based on shearing-tension and compression pattern, including iron core, magnet exciting coil, shearing magnetic current
Become elastomer, compression magnetic rheology elastic body, force transmission shaft.
Preferably, the iron core material is pure iron, is divided into upper and lower two pieces, symmetrically placed, passes through and compresses magnetic rheology elastic body
It is fixed to bond, and there are one through-holes among upper and lower iron core, can facilitate passing through for force transmission shaft.
Preferably, the magnet exciting coil be a pair, be fixed on iron core up and down two parts junction, by with extraneous power supply phase
Connection generates operating fields.
Preferably, the shearing magnetic rheology elastic body and compression magnetic rheology elastic body quantity are 2, and effect can be made to reach single
It is more than the several times of one pattern.
Preferably, the force transmission shaft is aluminium material, can fix bonding with upper and lower iron core by shearing magnetic rheology elastic body, on
Portion is used for connecting by vibration insolation means, and lower part connects vibration source, makes the iron core, the magnetic rheology elastic body, the force transmission shaft shape
At closed circuit, magnetic circuit leakage field is reduced.
Preferably, selected shearing magnetic rheology elastic body is the shear mode of two circular patterns, and connecting in magnetic circuit makes
With, and particle chain is moved towards in axial offset direction on the contrary, the mangneto that can improve damper exports energy in the two elastomers
Power simultaneously increases stability.
The utility model have it is simple in structure, easy to use, controllability is good, be capable of fast power-saving to vibration device into
Row vibration isolation and shearing-compression mixed mode can improve elasticity modulus, effectively carries out vibration isolation；And accessory is at low cost, technique
Simply, easy for installation, it can be produced with large-scale use.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model, wherein：1. force transmission shaft, 2. shearing magnetic rheology elastic bodies, 3. iron cores,
4. coil, 5. compression magnetic rheology elastic bodies.
Specific implementation mode
A kind of MR elastomer vibration isolator based on shearing-tension and compression pattern, including upper and lower iron core, magnet exciting coil, shearing
Magnetic rheology elastic body, compression magnetic rheology elastic body, force transmission shaft will produce operating fields when magnet exciting coil connects external power supply,
The modulus of magnetic rheology elastic body changes under magnetic fields, when power transmission axis connection vibration source, utilizes magnetic rheology elastic body
Magnetic effect, so that vibration isolator is achieved the effect that vibration isolation, when deenergization, magnetic field disappear, elastomer is restored to original again
Apperance, thus it is reusable, it is convenient and efficient.
