Progression of the vibratory analysis technique by improving the piezoelectric sensor measurement accuracy

Abstract

The piezoelectric sensor is the best choice for large industrial installations for instantaneous monitoring and premature fault diagnosis of electromechanical systems. In this work, we made a study on the piezoelectric detection and the piezoelectric sensor then a model of the physical behavior of this sensor extracted. The developed model of measurement accuracy as a function of the relative vibration movement is validated by experimental tests and simulation. The good choice of the damping rate allowed to improve the parameters of the sensor on the one hand and to advance the technique of vibratory analysis on the other hand.

Measuring Mean Frequency, Power, and Bandwidth: Key Parameters in Signal Analysis

“…This methodology plays a crucial role in preventing unexpected breakdowns, optimizing maintenance schedules, and extending the lifespan of machinery and structural components. As industries increasingly rely on advanced technologies, the role of vibration analysis becomes even more signi cant, contributing to improved reliability, e ciency, and safety in a diverse range of applications [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47].…”

Low-Cost Wireless Structural Health Monitoring of Bridges

“…Accelerometers are force-sensors that are broadly used for measuring vibrations [ 22 ]. According to [ 23 ], accelerometers are frequently set up on one of the following principles: Piezoelectricity: This is one of the most popular types of accelerometers in the industry for measuring [ 24 ], based on specific materials’ piezoelectric effect. For measuring the dynamic changes in mechanical variables, the piezoelectric effect of particular materials is used [ 25 ].…”

Development of a Low-Cost System for the Accurate Measurement of Structural Vibrations

“…The most common type of vibration sensing technology is based on one of the following three main principles: piezoelectricity, piezoresistivity, and differential capacitive measurement [28]. Piezoelectric accelerometers use the piezoelectric effect of certain materials to measure dynamic changes in mechanical variables [29] and can operate on a wide range of frequencies [30]. The piezoresistive accelerometers (also known as strain gauge accelerometers) work by measuring the change in electrical resistance of a piezoresistive element when mechanical stresses are applied [31].…”
