Project summary

Purpose of work

Basic objective of the activities is coordination and joining up the effort of specialists (designers, technologists, piezomaterial developers etc.) from different institutions and development of specific prospective piezoelectric sensors and piezotechnique devices.

In the framework of coordination of the activities it is supposed the exchange of experience and information (including separate technologies, methods, etc.) about the latest achievements of the project-participating institutions.

The project goal: is development of prospective sensors and piezotechnique devices (collisions sensors for motorcar safety systems, high temperature sensor of quick changing pressures, precision vibroacoustic, sensor).

In VNIIEF, NIIFI and ADIB in the framework of conversion in the 90th the development of the number of prospective sensors, were started but because of absence of conversion activities funding these works were terminated.

Realization of the project will allow to use prospective sensors and devices in the interests of national economy (to raise safety and reliability of motorcar safety systems various power plants being applied in aviation, engine manufacture, atomic power industry, missile manufacture for national economy purposes, to reduce costs of various control and diagnostic systems).

Development of collision sensor with the following supposed characteristics:


— possibility of reliable operation during 4 years, 2000 hours of driving not lower than 0,999 - 0,9998;
— possibility of false operation during the same period is less than 0,0008;
— sensor speed of response - 2–15 ms;
— sensor cost is less than 30$;
— sensor shall be selective, i.e. distinguishing the emergency situation from the impact of various destabilizing factors which appear during motorcar movement (shaking, vibration etc.);
— sensor design shall provide possibility of mass production.

Development of the hightemperature sensor of quickchanging pressure with the following supposed characteristics:


— the range of quick changing pressure measurements is: 0,005–5,6 MPa;
— the range of statistical pressure effect: 2,8–63 MPa;
— frequency range is: 40–50000 Hz;
— transformation factor is: 1,3ґ10-5 mV/Pa;
— error is: 5%;
— temperature of media being measured is: – 60 — +700 °С;
— vibration accelerations are up to 1000 m/s2;
— mass is: 0,04 kg;
— reliability is: 0,999;
— service life is: 10 years;
— sensor cost is: 250$.

Development of vibroacoustic precise sensor with the following supposed characteristics:


— operation frequency range, kHz is - 20–100;
— variation of AFR in accelerometric mode, dB is - less than 1,0;
— sensitivity (at minimum frequency 20 kHz), V/m is - more than 106.

During collision sensor development the following scope of works will be carried out:


— design documentation for test sample will be developed;
— estimation of serviceability and reliability will be accomplished;
— small set of 10-20 test samples will be manufactured;
— experimental research to confirm some basic sensor characteristics will be carried out.

During development hightemperature sensor of pressures the following scope of works will be carried out:


— design documentation for test sample will be developed;
— estimates of serviceability and reliability will be conducted;
— small set (5-10 items) of test samples will be manufactured;
— some experimental research to confirm some basis sensor characteristics will be carried out.

During development of precision vibroacoustic sensor the following scope of works will be carried out:


— design documentation for test sample will be developed;
— estimates of serviceability and reliability will be accomplished;
— small set (5-10 items) of test samples will be manufactured;
— experimental research to confirm some basic sensor characteristics will be accomplished.

The given project meets ISTS objectives to provide safiety and reliability of various designs and constructions (motorcars, power installations for different purposes, pipelines etc.) to transform scientific-technical military potential to activities fitting civil needs and will allow to achieve economic effect.

To obtain the expected results the Academy of Defense Industry Branches, VNIIEF, VNIIFI will use the following:


— scientific-technical experience in the field of piezoelectric sensors and piezotechnique devices production;
— production and technology basis for sensors, piezotechnique devices and electronic equipment production;
— high-skilled specialists including electronic engineers, programmers, designers, technologists, metrologists.
