Noise machines reduction through the use of piezoelectric ceramic transducers

Muradov I.B., Krjukov D.B., Kazantsev I.A., Shatalov N.V.

A scheme is proposed, in which the locations of the noise sources, special housings with ferroelectric ceramics coating that through direct and inverse piezoelectric record an acoustic signal with built-in microprocessor analyzes it and generates a response in anti-acoustic wave. As the technology of coatings applied ferroelectric ceramics gas-dynamic spraying. In this paper the dependence of the acoustic power of the change in the area of the electrode surface and the polarization voltage. To increase the effectiveness of noise reduction of working arrangements, where their amplitude – frequency characteristics are very different from each other, including the width of the preferred frequencies proposed multicell design ferroelectric ceramics layer.

Keywords: piezoelectric effect, acoustic power, frequency response, resonance frequency.

Features a segneticoceramic coatings by gasdynamic spraying

Muradov I.B., Krjukov D.B., Kazantsev I.A., Shatalov N.V.

This article shows the change in the basic properties of piezoelectric composite polymers depending on the nature of the distribution of the filler in the polymer matrix. Considered ten classes of composites with different types of connectivity of the filler to the polymer. Based on the theoretical analysis of the simplest of these composites are polymers with randomly distributed particles in it ceramic ball shape, is a model of piezoelectric and mechanical properties of the polymer-ceramic composite piezoelectrics. The theoretical dependence of the volume content piezo sensitivity ceramics for various types of composites. The basic concepts, principles and laws of the process gas dynamic spraying of powder materials, shows the stages of the process gas dynamic spraying. Are the main advantages and disadvantages of the gas-dynamic spraying using charge material with high density and low flowability.

Keywords: piezoelectric, composite, polymer, gas-dynamic spraying.
