Abstract
The present invention proposes a kind of magnetic rheology elastic body composite construction of implanting magnet exciting coil, it mainly is made up of magnetic rheology elastic body and magnet exciting coil, be implanted into magnet exciting coil at described magnetic rheology elastic body, magnet exciting coil is to be fixed in the mould when magnetic rheology elastic body is manufactured, with the magnetic rheology elastic body material injecting mould that mixes, the magnetic rheology elastic body raw material is slowly solidified, make magnet exciting coil be compounded in the magnetic rheology elastic body material internal, and reserve magnet exciting coil energising joint by integral body.This composite construction under the situation of energising conductive coil since electromagnetic induction effect in coil portion produce magnetic field, and the magnetic line of force of this magnetic field correspondence all passes magnetic rheology elastic body, by the exciting current in the continuous change coil, with regard to the elastomeric mangneto modulus of shearing of may command, and then regulate the variation of magnetic rheology elastic body actuator rigidity, thereby subdue various impacts and vibration in the engineering.
Description
Technical field
The invention belongs to the magnetorheological materials technical field, be specifically related to a kind of composite construction of implanting the magnetic rheology elastic body of magnet exciting coil.
Background technology
Magnetic rheology elastic body is a new branch of magnetorheological materials, is with a wide range of applications in fields such as Aero-Space, automobile, naval vessel, vibration controls.Magnetic rheology elastic body has magnetorheological materials and elastomeric advantage concurrently, has overcome shortcomings such as magnetic flow liquid sedimentation, poor stability again, thereby becomes the focus of magnetorheological materials research in recent years.Yet although new manufacture method is suggested at present, still there is the good inadequately and strong inadequately problem of magnetic effect of mechanical performance in the magnetic rheology elastic body of developing, and this has restricted based on the design of magnetic rheology elastic body device and application.Except the material self problem, also there is the low and magnetic field intensity penetrating projectile gonosome ability of externally-applied magnetic field application efficiency in magnetic rheology elastic body, the structure heaviness in application process; And when magnetic rheology elastic body deforms and magnetic field angle is arranged, cause magnetic flux density to diminish, thereby reduce the problems such as magnetic rheology effect of magnetic rheology elastic body.
Summary of the invention
The present invention proposes a kind of composite construction, promptly in magnetic rheology elastic body, implant magnet exciting coil, make a kind of composite construction, improve the relevant service behaviour of magnetic rheology elastic body from structure optimization magnetic rheology elastic body.
Technical scheme of the present invention is as follows:
A kind of magnetic rheology elastic body composite construction of implanting magnet exciting coil, it mainly is made up of magnetic rheology elastic body and magnet exciting coil, be implanted into coil with excitation function at described magnetic rheology elastic body, described magnet exciting coil is to be placed into before magnetic rheology elastic body is manufactured in the mould, and then inject the magnetic rheology elastic body raw material mixture of ferromagnetic particle and high molecular polymer (as be mixed with) in the mould, last under the effect of externally-applied magnetic field, solidify at a certain temperature, make magnet exciting coil be compounded in the magnetic rheology elastic body material internal, and reserve magnet exciting coil energising joint by integral body.For the uniform magnetization of magnetic rheology elastic body inside, fully realize magnetic rheology effect, described magnet exciting coil should be arranged in the centre position of magnetic rheology elastic body, and the shape of magnet exciting coil can change according to applied environment and the different of object with volume.
This composite construction the energising situation under as shown in Figure 2, conductive coil is because electromagnetic induction effect portion's generation in coil magnetic field, and the magnetic line of force of this magnetic field correspondence all passes magnetic rheology elastic body, by the exciting current in the continuous change coil, with regard to the elastomeric mangneto modulus of shearing of may command, and then regulate the variation of magnetic rheology elastic body actuator rigidity, thereby subdue various impacts and vibration in the engineering.
As seen the present invention has tangible advantage mutually with prior art:
1) on the producing method in magnetic field, this composite construction adopts the internal motivation method, replaces original outside to add magnetic method.Unequal unfavorable phenomenon is passed through in leakage field and the magnetic field that can avoid like this occurring when adding the action of a magnetic field in elastomer, thereby has improved the utilance in magnetic field to a certain extent.
2) aspect mechanical structure, this composite construction has been owing to cancelled the exciting bank of externally-applied magnetic field, not only lightweight structure, saved material, reduced processing, and made elastomeric application more flexible, more extensive, no longer be subjected to the constraint of externally-applied magnetic field.
3) because magnet exciting coil copper coil normally, has good bullet flexibility, when limited deformation takes place in this composite construction under external force, conductive coil will move with elastomer, will make that like this chain structure direction of ferromagnetic particle remains unchanged in magnetic direction that hot-wire coil forms and the elastomer, thereby make the mangneto modulus of shearing be always maximum, more help the control of electric current rigidity.
4) the present invention has characteristics such as simple in structure, that preparation cost is low, modulus of shearing is big, can be widely used in the engineering practical application.

Embodiment
At first magnet exciting coil 3 is fixed in the mould, and the high molecular polymer of liquid state is evenly mixed with the ferromagnetic particle material; Then mixture is injected mould, ferromagnetic particle at this moment will become random distribution; Add the stationary magnetic field that is produced by permanent magnet 4 at last this structure, it is slowly solidified at a certain temperature, at this moment magnetic field will cause ferromagnetic particle to form labyrinths such as chain, in the process of solidifying, magnet exciting coil 3 will closely combine with chain magnetic-particle structure with basis material, and still keep this structure constant after curing.Magnet exciting coil 3 promptly is compounded in magnetic rheology elastic body 2 material internals by integral body, and reserves magnet exciting coil energising joint 1, and structure as shown in Figure 1.
When making, preferably magnet exciting coil 3 is arranged in the centre position of magnetic rheology elastic body 2, the shape of magnet exciting coil 3 is chosen according to applied environment and the different of object with volume.The placement direction of magnet exciting coil 3 should satisfy: magnet exciting coil 3 is under the energising operating state, the main field direction that magnet exciting coil 3 is produced should be relevant with the mode of operation of magnetic rheology elastic body 2, under shear mode, its direction should with magnetic rheology elastic body 2 because of stressed take place the mangneto shear action the direction of corresponding working face consistent; Under squeeze mode, its direction should be consistent with the direction of extruding force or opposite.
As shown in Figure 2, conductive coil is because electromagnetic induction effect can produce magnetic fields in magnet exciting coil 3 inside to this composite construction, and the magnetic line of force 5 of this magnetic field correspondence all passes magnetic rheology elastic body 2 under the situation of energising.By changing the exciting current in the coil, control elastomeric mangneto modulus of shearing, and then regulate the variation of magnetic rheology elastic body 2 actuator rigidity, thereby subdue various impacts and vibration in the engineering.
