Réduction des vibrations des machines à réluctance variable à l'aide d'actionneurs piézoélectriques

Abstract : This work presents a vibration damping using piezoelectric actuators for switched reluctance machine in order to decrease the emitted acoustic noise. The study specifies the different noise sources, and details the magnetic one, which is dominating. The introduction of the piezoelectric actuators and their use for the vibration damping need the development of an analytical model of their action on the mechanical structure. This last is compared to the finite element results, and then used to optimised the design and location of these actuators. Several numerical controllers are developed and evaluated on experimental prototypes to validate the effectiveness of the solution. Finally, the scale effect is studied to evaluate the viability of the solution on bigger structures.
