Réalisation d’un banc d’essai pour l’étude des défauts de roulements

Abstract

The prognosis of the Remaining Useful Life (RUL) of mechanical systems is one of the main objectives of industrial maintenance. This project consists of creating a test bench for the prognosis of bearing defects. The bench is essentially composed of an electrical motor with its control, a pair of bearings, a tested bearing, and a loading system in order to accelerate the failure of the bearings. The first part involves assembling the different elements. In the second part, it involves acquiring vibration signals from the beginning of tests until the appearance of defects. The acquired signals will subsequently be used to test different prognosis techniques under different conditions.
