Implementation Features of Tribological Sensors Based on Piezo-Transformer Measuring Converters with Two Degrees of Freedom
УДК 53.087.92
Abstract
The paper discusses the aspects of the creation of tribological sensors based on coupled vibrations. The dependence of the ratio of the output voltages of piezoelectric transformers on the magnitude of the exciting voltage at the first and second normal synchronization frequencies with different amount of exerted pressure is presented. Peculiarities of trisensitivity mechanism implementation in sensors based on piezo-transformer measuring transducers with two degrees of freedom are considered. It is shown that physicomechanical properties of the contact area can be examined by measuring the parameters of coupled oscillations of the contacting piezoelectric resonators. Also, it is possible to set the required operating modes of the piezoelectric resonators of tribological sensors by adjusting the amplitude of oscillation of the piezoelectric resonators and, respectfully, the amplitude of mutual micro-movements of contacting surfaces. The proposed method of measuring the sensitivity is suitable for estimation of hardness and surface roughness of materials, the elastic moduli of longitudinal and shear deformations, the coefficients of rolling friction, slip, and rest, etc.
