Modélisation numérique discrète innovante pour le monitoring électrique des roulements (original) (raw)

This work deals with the modeling of the mechanical and kinematic state of a ball bearing using Discrete Elements Method (DEM). An electromechanical coupling is introduced to extract an electrical and measurable response of a bearing in operation, for monitoring and diagnostic purposes. Recent research activities at the LTI have helped us to measure, to understand and to simulate the electrical response of static multi-contact systems. In this work, we have been interested in both multi-scale and multi-physics modeling of ball bearings in dynamics where mechanical and electrical effects, induced by the lubricated contact are studied Mots clefs : MED, Contact lubrifié, couplage électromécanique, roulement, monitoring, usine du futur, jumeau numérique 23 Congrès Français de Mécanique Lille, 28 au 1 Septembre 2017
