Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
As shown in the picture, this U-shaped piezo-electricity composite material energy converter is made of U-shaped piezo-electricity composite material, energy converter energy
Form the broad beam that a two sides energy is gradually increased relative to center.
The U-shaped piezo-electricity composite material, U-shaped to use hyperbolic cosine line style, hyperbolic cosine formula is as follows:
Cosh (x)=[ex+e-x]/2
Wherein the opening size of U-shaped hyperbolic cosine is 0.16m.
The piezoelectric element is arranged by positioning mold according to hyperbolic cosine line style, is perfused in the gap of element poly-
Object is closed, solidification rear surface is ground, carries out Electrode treatment to surface by way of magnetron sputtering and vapor deposition, finally carry out water
Close processing.To obtain the high-frequency wide-beam energy converter that two sides signal gradually increases.
The cell sizes of the piezo-electricity composite material are 2.5mm × 2.5mm × 4.8mm, and material PZT4 utilizes array element
Thickness vibration reduces its coupled vibrations.
The two sides signal of the U-shaped piezo-electricity composite material transducer directivity increases 13dB or more than center.
The beam angle of the working frequency 300kHz of U-shaped piezo-electricity composite material energy converter, energy converter 300kHz are greater than 160
The signal of degree, two sides increases 13dB or more than center, as shown in the picture.Voltage is sent within the scope of 260~320kHz of response
Fluctuating be 6dB (attached drawing 2).
1: the design of array element
In order to meet the working frequency of 300kHz, needs to optimize the size of array element, using the thickness vibration of array element, avoid it
Close coupling vibration area, due to working frequency 300kHz, array element controls battle array with a thickness of 5mm or so by adjusting lateral dimension
The resonance frequency of member, when being closer to because of lateral dimension with extensional vibration size, coupled vibrations is stronger, is unfavorable for thickness direction
Vibration, therefore lateral dimension is less than thickness direction as far as possible, meanwhile, consider the operability and actual work frequency of preparation
Rate, select array element with a thickness of 4.8mm, lateral dimension is 2.5mm × 2.5mm, reduces coupling in the case where meeting frequency requirement
Close vibration.
On the other hand, due to being transmitting transducer, array element is using PZT4 material.
2: positioning mold design
Main beam center increases to two sides uniformly continuous so that transducer array aperture function must continuous, even variation；
Meanwhile so that the radius of curvature of composite material aperture function each point is not identical, the radius of curvature of center is less than the song of two sides
Rate radius, and the radius of curvature changed must guarantee that the line style of mold need to meet hyperbolic cosine curve by accurately mold,
It to be designed simultaneously in conjunction with the size of piezoelectric element.
3: hyperbolic cosine is structured the formation
It is prepared different from general composite material, the wave beam that two sides gradually increase in order to obtain, we use hyperbolic cosine
It structures the formation, considers that the operability of the broad beam of directive property and technique of structuring the formation, the spacing of array element are solid matter, the opening of hyperbolic cosine
Having a size of 0.16m, the positive extreme direction of piezoelectric element is unified outside, after the good battle array of cloth, is fastened piezoelectric element using mold.
4: perfusion polymer
After the good battle array of cloth, the filled polymer in the gap of array element will be first to polymer in the filling process of polymer
Glue carries out vacuumize process, prevents concealing for air bubble, meanwhile, when perfusion, also needs to vacuumize it and heat treatment, with
Guarantee to be each filled with polymer between each array element, proposes high performance consistency.The production method technique being perfused afterwards of first structuring the formation in this way is simple
It is single, when will not occur composite material bending due to outer surface by pulling force and internal stress is unbalance caused by inner surface compression chord
Phenomenon.
5: grinding and Electrode treatment
The working frequency designed in order to obtain carries out inner surface and appearance to the hyperbolic cosine piezo-electricity composite material being perfused
Its thickness is milled to design size by the grinding in face, is then carried out cleaning treatment to surface, is utilized magnetron sputtering or vapor deposition side
Formula makes silver layer, to obtain the anode and cathode of piezo-electricity composite material.
6: hyperbolic cosine composite material watertight
To meet the use and performance test of transducer array in water, watertight processing is carried out to its surface, in outer lateral irrigation
The waterproof material of one layer of 3mm thickness of note, material are polyurethane.
The cable that the positive and negative polarity wire of energy converter passes through band shielding is drawn after perfusion, cable and energy converter metal back seat it
Between connected by watertight cable head.
It is understood that it will be understood by those skilled in the art that being subject to technical solution of the present invention and inventive concept
It all should fall within the scope of protection of the appended claims of the present invention with replacement or change.
