FIELD: electricity.

SUBSTANCE: invention relates to piezoelectronics. Essence of the invention: the working body of the high-voltage generator is formed by inertial mass and a package of the plates of polarised composite ferroelectric materials with high values of piezoelectric voltage coefficient and compressive strength pre-set for each plate. The distances between the conducting surfaces applied on the plates is set such that their values multiplied by values of mechanical stress and piezoelectric stress coefficient be identical to each plate in the package. The method comprises the manufacture of each batch of the plates polarised composite ferroelectric materials by consecutive execution of the following operations: preparation of moulding powder of the synthesised material, preparation of mix of moulding powder of the synthesised material and pore agent, moulding from mix of work-pieces and their high-temperature processing by an agglomeration method, machining, metallisation, polarisation and measurement of parameters.

The invention relates to electronics, and more specifically, to piezoelectronic, converters of mechanical energy into electrical energy, to the sources of the electric charge of high voltage-based piezoelectric ceramics.

Known piezoelectric devices - mechanical energy Converter into electrical energy. The transformation of energy by deformation of the piezoelectric element consisting of a polarized ferroelectric ceramics, occurs in the piezoelectric sensors (V. V. Ancic. Piezoelectric transducers. Rostov-on-don, Publishing house "SFU", 2010), and in household appliances - pezozazhigalok - formed high-voltage discharge. When the longitudinal relative to the residual vector polarized, deformation of the compression-tension of the piezoelectric element under the action of a force applied normal to the planes of the electrodes by a piezoelectric effect, the electrodes of the charge.

Known explosive generators for meteorological applications, which converts the mechanical energy of the shock wave propagating in the working medium, high voltage electrical energy (Presedence A. B., D. V. Tretyakov, Sekachev M. V. the energy Balance of the explosive piezoelectric oscillator frequency. Proceedings of the conference "Magagawa and Meg�voltage application technology", Sarov, VNIIEF, 1997, p. 954÷958). The main element of such generators is the working medium, for execution as a batch of n wafers polarized ferroelectric material coated with conductive surfaces. The shock wave in the working medium is formed by a special explosive charge. The advantages of the considered devices are compact and can be completely Autonomous from external power sources.

The explosive shock wave has a greater intensity, and the dominant process in the conversion of mechanical energy of the shock wave into electrical energy is the transition of ferroelectric paraelectric state in.

Source current i_{E}and the resulting charge Q, under the assumption about linearity of the material properties of the working fluid, can be estimated by the formulas:

where: n is the number of plates of the ferroelectric material coated with conductive surfaces;

Δ - leap of polarization at the shock front;

u_{E}- the velocity of the shock wave front, u_{E}equate to the speed of sound in the working medium;

S_{E}- the area of the contact surfaces of the ferroelectric working body;

δ=nh - the path of the shock wave ferroelectric working body;

h - the distance between the contact�and ferroelectric surfaces of the plates;

t=δ/u_{E}the current flow.

Known explosive piezoradiator (patent RF №2154888, prototype) comprises a shock wave generator, a piezoelectric transducer shock wave energy into electrical energy, in the form of one piezoplates with electrodes on two opposite faces parallel to the direction of propagation of the shock wave.

The disadvantages of these designs include a high voltage generator:

- in the presence of explosive generators explosives and the accompanying system initialization to create a shock wave;

- the presence of a source of electrical energy (battery, batteries and electronic components for the formation of high voltage;

- relatively small values of emerging charge per unit volume of the working fluid when high values of the potential difference applied between the plates of the conductive surfaces.

Task to be solved by the present invention is, while maintaining the advantages (compactness and full autonomy), the achievement of the technical result is:

- in the creation of a high-voltage generator, which excludes the presence of explosives, which converts the mechanical shock in high voltage electrical energy through working�about the body of piezoelectric high voltage generator under the influence of a shock wave for example, in shot volume type VOG-25 grenade launcher type GP-25;

- reduced time of education and increase the value of emerging electric charge per unit volume of the working fluid at high values of the potential difference applied between the plates of the conductive surfaces.

The problem is solved in piezoelectric high voltage generator consisting of an inertial mass and laminations polarized ferroelectric composite materials with high piezoelectric voltage coefficient and defined for each plate compressive strength, mechanically connected in series so that the resulting plate at impact mechanical stresses are added together and electrically connected in parallel so that the cumulative arising in plates electric charges with the same potential difference, which is the distance between a deposited conductive plate surfaces are set such that their values are multiplied by the values of mechanical stress and piezoelectric voltage coefficient, were the same for each plate in the package, and the working fluid is subjected to a shock wave; and placed, for example, in shot volume type VOG-25 grenade launcher t�PA GP-25.

In the proposed design of the high-voltage generator (Fig. 1A), placed, for example, in shot volume type VOG-25 (Fig. 1B), the working fluid represents the inertial mass M_{0}and the batch of n wafers polarized ferroelectric composite materials (Fig. 1B) the density ρ_{k}with high values of the piezoelectric voltage coefficientand specified for each k-th plate having a compressive strength of_{k}, what distance h_{k}between applied to the conductive plate surface area of S_{k}set such that the values of h_{k}multiplied by the values of the mechanical stresses

Characteristics of the k-th plate of the high voltage generator according to previously identified and presented experimental regularities and constants are described by the following formulas

Plates in the package are connected mechanically in series so that the mechanical stresses

- for "header", the n-th plate (k=n)

- for the k-th plate

where a is the acceleration voltage of the generator at a blow;

S_{n}- contact surface, "upper", the n-th plate.

Equating for the k-th inserts the value of_{k}shown in formulas (3) (4) and (5) determine the desired porosity P_{k}composite and porosity corresponding to that permittivity values

Plates are connected electrically in parallel so that summarized the emerging electric charges with the same potential differencefor what value of the distance h_{k}determined from the continuity condition worksfor each plate.

The maximum time of occurrence of charges with the same potential difference U_{k}it can be estimated at the time of passage of the shock wave (compression wave) at the plate with a maximum value of h_{k}that is substantially less than the transit time of a wave of compression consistently across all plates.

When the acceleration values that contribute to the excess of the compressive strength, the process of conversion of mechanical energy of compression into electrical energy occurs simultaneously in all the plates of the working fluid and with�avoideda leap of polarization on the wave front of the compression in the transition of ferroelectric paraelectric state in.

The increase in the value of emerging electric charge per unit volume of the working fluid at high values of the potential difference applied between the plates of the conductive surfaces follows from the dependences in Fig. 2A) and 2B).

Fig. 2A schematically shows the dependence of pesumably d_{33}and d_{31}and d_{v}from porosity R. If the values of the transverse piezomodule d_{31}with increasing porosity decreases, the volumetric piezomodule d_{v}grows, the amount of longitudinal piezomodule d_{33}that determines the charge remains practically unchanged, and the value of the coefficient of the voltage is proportional towith increasing porosity increases.

Thus, the hallmark of a high voltage generator that converts the energy of the shock wave mechanical compression into electrical energy, is the working fluid that is subjected to a shock wave, for example, in shot volume type VOG-25 grenade launcher type GP-25, which represents an inertial mass and the laminations of polarized ferroelectric composite materials with high piezoelectric voltage coefficient and defined for each plate compressive strength, mechanically connected in series so that who�typewriter in plates under impact, the mechanical stresses are summed, and electrically connected in parallel so that the cumulative arising in plates electric charges with the same potential difference, which is the distance between a deposited conductive plate surfaces are set such that their values are multiplied by the values of mechanical stress and piezoelectric voltage coefficient were the same for each wafer in the batch.

The specified set of distinctive features of the invention allows to achieve a technical result consists in:

- the establishment of a piezoelectric high voltage generator charge, for example, in shot volume type VOG-25 grenade launcher type GP-25, which converts the mechanical compressive stress arising from the shock generator to electrical energy and eliminating any explosive substance;

- reduction of time of education and increase the value of emerging electric charge per unit volume of the working fluid at high values of the potential difference applied between the plates of the conductive surfaces.

The formation of the electric charge occurs simultaneously in all the plates and can be assessed at the time of passage of the compression wave on the plate with the greatest distance between the conductive surfaces. Difference p�of tentelow charges on the conductive surfaces of the plates are the same and equal to

A method of manufacturing the inventive high-voltage generator. The process of manufacture of high voltage generators includes the manufacture of:

- plates of polarized ferroelectric composite materials with high piezoelectric voltage coefficient and defined for each plate compressive strength;

packages of plates mechanically connected in series (in a column) so that arise in the plates during acceleration mechanical stresses are added together and electrically connected in parallel so that the cumulative arising in plates electric charges;

build a high voltage generator in the case of a porous polymeric material, including Assembly of the working fluid from the inertial mass and the package of plates and current collectors, in the case of a porous polymeric material.

The process of manufacturing plates of porous piezoelectric ceramics for generator starts with the preparation of batches of mixtures of press powder synthesized material powder and a blowing agent, e.g. corn starch or methylcellulose. Press the powder of the synthesized material, for example PZT-46, is made from powder synthesized material having a total specific surface area in the range of (1±0,1) m^{2}/g device PSC-4, and the size zere� powders organic blowing agent,
for example methylcellulose, Ø=6±1 µm. For each plate a batch of a mixture prepared separately in the apparatus of the mixing vortex layer (ABC), where the chaotic motion of magnetic working media, such as steel needles for gramophones, is determined by the rotating magnetic field of the stator three-phase motor. Volumetric content of blowing agent in the mixture is laid during loading and is controlled by the value of the bulk weight of the mixture.

Pressing batches of mixtures of powders produced in the moulds, the size of which take into account shrinkage during sintering up to 45% and the required machining allowances.

The sintering of the preforms is carried out in a lead-containing filling for special temperature-time mode, which provides the temperature rise at a rate of 25±3°C/h, holding at the temperature of 450±10°C for a 2.0±0.1 hour to burn off the ligaments and blowing agent powder; sintering is carried out at a temperature of 980±10°C for 3 hours.

Sintered workpiece is polished by diameter and, as a purely in-plane, with an allowance for height up to 5 mm.

On the grinded workpieces determine the density of geometrically as the ratio of mass to volume (weighing in the balance with an error of not more than 0.1%, the sizing of the caliper with a scale division of 0.01 mm. the Total error of determining the density is estimated as not offset�sort of 1.0%. Polished billet optionally, up to 10% of each batch is made probes, determine electrophysical parameters and subjected to compression in a hydraulic press, determining the compressive strength.

Billet parties with different density (porosity) grind in size according to the height defined by the probes, in accordance with the computed values.

The metallization of porous flat surfaces of the workpieces is carried out in the traditional way, with the application of silver paste through screen printing with edges and a silver-containing brazing paste with the value of porosity up to 25% when the porosity is closed. In the blanks with open (through) porosity (greater than 25%) by brazing with silver metallization occurs only pads, and then sprayed through a mask with silver edges on all flat surfaces.

The polarization of the workpieces is carried out on the modes selected on the probes, for example at a temperature of 120±3°C and the field strength of 2.0±0.1 kV/mm in an hour.

The described method uses known technology, but does not ensure the production of plates with the required set of parameters.
