Abstract
The invention discloses a kind of magnetic rheology elastic body and preparation method implanted magnet exciting coil and have Magnetic Memory function, be implanted with magnet exciting coil in described magnetic rheology elastic body, in described magnetic rheology elastic body, Uniform Doped has powder permanent magnet material.The present invention is by permanent magnet material of adulterating in magnetic rheology elastic body, by having different magnetic flux densities after magnet exciting coil is applied pulse current, it is not required to be continually fed into exciting current to maintain required magnetic flux density, greatly reduces energy consumption required during magnetic rheology elastic body work.
Description
Technical field
The invention belongs to the preparation of advanced composite material (ACM), particularly relate to the improvement of magnetorheological materials.
Background technology
Magnetic rheology elastic body is a kind of novel intelligent material, and mechanical property etc. is controlled with externally-applied magnetic field.The advantage that magnetic rheology elastic body has magnetorheological materials and elastomer concurrently, as responded soon, good reversibility, controlled ability are strong, overcome again magnetorheological fluid sedimentation, poor stability, need the shortcomings such as sealing device, have broad application prospects in the field such as vibration and noise reducing, intelligent-induction.But needing to maintain the existence of certain magnetic field in magnetic rheology elastic body application process, realize generally by being continually fed into electric current in coil at present, this necessarily causes power consumption bigger.
Summary of the invention
Goal of the invention: for the problem and shortage of above-mentioned existing existence, it is an object of the invention to provide a kind of magnetic rheology elastic body implanted magnet exciting coil and have Magnetic Memory function.
Technical scheme: for achieving the above object, the present invention is by the following technical solutions: a kind of magnetic rheology elastic body implanted magnet exciting coil and have Magnetic Memory function, being implanted with magnet exciting coil in described magnetic rheology elastic body, in described magnetic rheology elastic body, Uniform Doped has powder permanent magnet material.
As preferably, described permanent magnet material is alnico or Nd-Fe-B permanent magnet material.
As preferably, described permanent magnet material is alnico.
Another object of the present invention there is provided a kind of above-mentioned implantation magnet exciting coil and has the preparation method of magnetic rheology elastic body of Magnetic Memory function, comprises the following steps: a, by fixing for magnet exciting coil in a mold；B, in the magnetic rheology elastic body raw material of flow-like, mix Al-Ni-Co permanent magnet powder, and mix homogeneously；It is then injected into described in step a in mould, magnet exciting coil is wrapped up, and reserves F terminal；C, last under additional the action of a magnetic field, make magnetic rheology elastic body slowly solidify, complete.
Beneficial effect: compared with prior art, the invention have the advantages that by permanent magnet material of adulterating in magnetic rheology elastic body, by having different magnetic flux densities after magnet exciting coil is applied pulse current, it is not required to be continually fed into exciting current to maintain required magnetic flux density, greatly reduces energy consumption required during magnetic rheology elastic body work.
Accompanying drawing explanation
Fig. 1 is the structural representation of ultrasonic actuation means of the present invention.
Wherein, magnetic rheology elastic body 1, magnet exciting coil 2, externally-applied magnetic field 3.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, it is further elucidated with the present invention, it should be understood that these embodiments are merely to illustrate the present invention rather than limit the scope of the present invention, after having read the present invention, those skilled in the art all fall within the application claims limited range to the amendment of the various equivalent form of values of the present invention.
As it is shown in figure 1, a kind of magnetic rheology elastic body implanted magnet exciting coil and there is Magnetic Memory function, first magnet exciting coil 2 is fixed in a mold.Al-Ni-Co permanent magnet material the mix homogeneously of powder is added in magnetic rheology elastic body 1 raw material, it is then injected in mould, it is connected on and makes magnetic rheology elastic body 1 slowly solidify under the effect of externally-applied magnetic field 3, magnet exciting coil 2 is fixed on magnetic rheology elastic body 1 inside the most at last, and reserves magnet exciting coil 2 joint.The shape of the most all previous coil and volume can be according to applied environment and the difference of object and changes.In the present invention, adulterated al nickel cobalt powder of permanent-magnet material in common magnetic rheology elastic body 1, the magnetic field that it produces can be changed by additional pulse current, i.e. changes the magnetic flux density of permanent magnet by being passed through the different pulsed field magnetization electric current of size and Orientation to coil.Permanent magnet material can be magnetized or degaussing by additional pulse current, and after electric current removes, this permanent magnet material is still provided that the magnetic field needed for magnetic rheology elastic body 1, such that it is able to reduce energy consumption required when magnetic rheology elastic body 1 works.
Claims (2)
1. implant magnet exciting coil and have the magnetic rheology elastic body of Magnetic Memory function for one kind, described magnetic rheology elastic body is implanted with magnet exciting coil, it is characterized in that: in described magnetic rheology elastic body, Uniform Doped has powder permanent magnet material, described permanent magnet material to be alnico；The magnetic flux density of permanent magnet material is changed by being passed through the different pulsed field magnetization electric current of size and Orientation to magnet exciting coil；Permanent magnet material can be magnetized or degaussing by additional pulse current, and after electric current removes, this permanent magnet material is still provided that the magnetic field needed for magnetic rheology elastic body.
