Decrease of the resonance phenomenon effect and progress of the piezoelectric sensor correctness

In this work, an equation relates the natural frequency of the piezoelectric accelerometer with the relative frequency of vibratory motion has been proposed to choose the better frequency ratio and reduce the effect of the resonance phenomenon. The simulation results of the model developed have shown that the right choice of the frequency ratio makes it possible to reduce the measurement error and the effect of the resonance phenomenon as well as the increase of the accelerometer accuracy.

I. Introduction

The maintenance of production assets is largely based on the state of the mechanisms necessary for operation, nobody is unaware of the importance of regular maintenance for the availability of machines, but when it comes to ensuring the safety of goods, people and the environment, maintenance is notoriously insufficient and requires finer approaches developed in maintenance strategies.
