Specific implementation mode
Embodiment
It is that 0.5mm is constant that the magneto-electric coupled composite material, which keeps the thickness of Terfenol-D, Ni thickness be respectively 0.2mm,
0.5mm, 1mm prepare positive and negative magnetostrictive layer (Terfenol-D and Ni) thickness ratio and do not remain 1:0.4、1:1、1:2
Three kinds of samples.
Step 1：Two pieces of glass slides are taken, it is one of to be cut to long 15mm, wide 5mm, thickness 1mm, i.e. size with glass cutter
For the strip of 15mm × 5mm × 1mm, then the strip sheet glass cut vertically is sticked to separately by using epoxy resin
On one piece of glass slide, a T-type structure is formed, places 48 hours and dries, do 3 altogether.
Step 2：The Terfenol- for being 15mm × 5mm × 0.5mm with size by the PZT that size is 20mm × 5mm × 1mm
D is bonded in the front of PZT with epobond epoxyn, and wherein the two of PZT ends are respectively kept with the part of vacating of 2.5mm, so
The nickel sheet that size is 15mm × 5mm × 0.2mm, 15mm × 5mm × 0.5mm, 15mm × 5mm × 1mm is used into asphalt mixtures modified by epoxy resin respectively afterwards
Fat adhesive is sticked to the reverse side of PZT, and corresponding with positive Terfenol-D, and thickness ratio is made Wei 1:0.4、1:1、1:2
Three samples, place and dry for 48 hours.
Step 3：The sample that step 2 is prepared is adhered to epoxy resin on the T-type glass structure of step 1,
Then it is placed to dry, beam type Terfenol-D/PZT/Ni layered electromagnetics coupling composite material shown in FIG. 1 is finally made
Sample.
The high bias magnetic field for applying 400Oe to the sample obtained by the above method, obtains Terfenol-D/ shown in Fig. 3
PZT/Ni magneto-electric coupled coefficient relational graphs with frequency change under cantilever beam structure.Wherein direct magnetostriction layer Terfenol-D
Thickness is 0.5mm, and negative magnetostriction layer Ni thickness is 0.2mm, 0.5mm, 1mm so that positive and negative magnetostrictive layer thickness ratio is other
It is 1:0.4、1:1、1:2.Under cantilever beam structure, there are six formants in lamellar composite magnetoelectricity structure, including three
Flexural vibrations peak, three length vibration peaks.It is 1 when Ni thickness is the i.e. positive and negative magnetostriction layer thickness ratios of 0.5mm:When 1, second order is curved
Bent vibration peak reaches maximum value, and magneto-electric coupled coefficient is 1.38V/cmOe, and first-order bending vibration peak is greatly lowered, when Ni thickness
It is 1 that degree, which is 1mm, that is, positive and negative magnetostriction layer thickness ratio,:When 2, first-order bending vibration peak reaches maximum value, and magneto-electric coupled coefficient is
1.34V/cmOe, and second order bending vibration intensity is greatly lowered.Under high bias magnetic field, direct magnetostriction layer
The magnetostrictive effect of Terfenol-D is much larger than the magnetostrictive effect of negative magnetostriction layer Ni, thus in PZT and magnetosphere
Layer coupling occur mainly in the interfaces Terfenol-D/PZT, magnetoelectricity voltage signal is dominated by the interface coupling, and lower surface
Ni layers to the contribution very little of magneto-electric coupled signal, and because itself and PZT layers bond together, the Ni layers of negative magnetic shown
It causes flex effect that can compress PZT layers, forms certain clamping action, weaken length vibration coupling；With the increase of Ni thickness, folder
Holding effect should enhance therewith, and clamping effect helps to enhance the especially bending vibration of low-frequency resonance intensity, and it is strong to reduce high-frequency resonance
Degree.So under high bias magnetic field, there is multifrequency resonance in the magnetic electric compound material with cantilever beam structure, and by changing just
Oscillation intensity of the negative magnetostriction layer thickness than different vibration modes can be regulated and controled, with the increasing of negative magnetostriction layer Ni thickness
Add, low frequency bending vibration enhancing.
Unlike expressed above, Fig. 4 is the magneto-electric coupled composite material Terfenol- at low bias magnetic field -50Oe
D/PZT/Ni magneto-electric coupled coefficient relational graphs with frequency change under cantilever beam structure.Wherein direct magnetostriction layer
Terfenol-D thickness is 0.5mm, and negative magnetostriction layer Ni thickness is 0.2mm, 0.5mm, 1mm, positive and negative magnetostriction layer thickness
Than being respectively 1:0.4、1:1、1:2.Under low bias magnetic field, equally there are six formants in layered electromagnetic composite construction,
Include three flexural vibrations peaks, three length vibration peaks, peak position with measured under high bias magnetic field it is consistent.With negative magnetic
The increase of stretchable layer Ni thickness is caused, formant is all to high-frequency mobile.When Ni thickness is 0.2mm, that is, positive and negative magnetostriction layer thickness ratio
It is 1:When 0.4, first-order bending vibration intensity and single order length oscillation intensity are all bigger；When Ni thickness is 0.5mm, that is, positive and negative magnetic
It is 1 to cause flexible layer thickness ratio:When 1, second order bending vibration intensity reaches maximum, and magneto-electric coupled coefficient is 0.75V/cmOe；When
Ni thickness is that the i.e. positive and negative magnetostriction layer thickness ratios of 1mm are 1:When 2, resonance peak intensity is all greatly lowered.In low bias magnetic field
Under, Terfenol-D is suitable with the magnetostrictive effect intensity of Ni, and the magnetostrictive effect of the two is vied each other at this time.Positive and negative magnetic
It is 1 to cause flexible layer thickness ratio:When 0.4, the magnetostrictive effect of Terfenol-D is better than Ni, is mainly risen to PZT for Ni layers at this time
Clamping action；Positive and negative magnetostriction layer thickness ratio is 1:When 1, Terfenol-D is suitable with the magnetostrictive effect of Ni, causes to grow
The stretching vibration in degree direction is greatly lowered, but second order bending vibration intensity improves；Positive and negative magnetostriction layer thickness ratio is 1:2
When, the magnetostrictive effect of Terfenol-D is weaker than the magnetostrictive effect of Ni, and the negative magnetostriction characteristic of Ni is to PZT layers at this time
Play compression, it is suppressed that all high-frequency resonance patterns, only first-order flexure formant have larger intensity.
From among the above it is recognised that lamellar composite magnetoelectricity structure Terfenol-D/PZT/Ni under cantilever beam structure
Six resonant frequencies, including three flexural resonance frequencies, three length resonant frequencies.Under the action of bias magnetic field, with
Positive and negative magnetostriction layer thickness than difference, resonance mode can also change：Under high bias magnetic field 400Oe, positive and negative magnetic
It is 1 to cause flexible layer thickness ratio:When 1, second order bending vibration intensity reaches maximum, and first-order bending vibration intensity is greatly lowered；Just
Negative magnetostriction layer thickness ratio is 1:When 2, first-order bending vibration intensity reaches maximum, and other resonance peak intensities are all significantly
It reduces；Under low bias magnetic field -50Oe, positive and negative magnetostriction layer thickness ratio is 1:When 0.4, first-order bending vibration shakes with single order length
The Oscillation Amplitude of dynamic model formula is all bigger；Positive and negative magnetostriction layer thickness ratio is 1:When 1, second order bending vibration intensity reaches most
Greatly；Positive and negative magnetostriction layer thickness ratio is 1:When 2, first-order bending vibration has maximum intensity value, others resonance peak intensity all big
Amplitude reduction.
Therefore, we can with it is concluded that：In the layered electromagnetic coupling composite material with cantilever beam structure, by changing
Become the thickness ratio of positive and negative magnetostriction materials, effective regulation and control can be realized to the resonance mode of compound magnetoelectric material.
