Improvement of the vibration analysis technique by optimizing the parameters of the piezoelectric accelerometer

Condition-based maintenance is the most advanced form of maintenance because it is based on the actual state of the machine. It allows for better manage the interventions according to the state of the machine, its wear, or its degradation. The most widely used technique for this type of maintenance is vibration analysis because it detects the majority of faults in rotating machines. In this work, we studied the piezoelectric sensor which is considered the first element of the vibration measurement chain, and the modeling and simulation of the latter allowed us to improve their characteristics and their performance.
