BACKGROUND :
Background to the subject
The development of lightweight structures in the aerospace and automotive industries has introduced new technical challenges related to vibration and noise. In response, dynamic absorbers are attracting growing interest as a means of attenuating vibrations. The main challenge in their design is their sensitivity to frequency changes. A slight shift in resonance frequencies can have a considerable impact on attenuation performance.
The FAPARVA project therefore aims to study the development of piezoelectric absorbers, enabling resonant frequencies to be adjusted. The aim is to provide a theoretical and experimental overview of its influence, and to develop a method for sizing absorbers.

INTERNSHIP CONTENT :
The trainee will first model piezoelectric absorbers using calculation software (Matlab or Python). The models will take into account mechanical, electrical and electromechanical parameters, in order to study their influence on vibration behavior. The student will then propose methods for designing optimal piezoelectric systems. The project will then focus on the technical implementation of proofs of concept. A vibration test rig will be designed using equipment available in the laboratory, and with the help of the mechanical technician. Experiments will include vibration measurements and analysis of the influence of electrical interfaces.

LABORATORY PRESENTATION
The SYMME ("Systèmes et Matériaux pour la Mécatronique" - Systems and Materials for Mechatronics) laboratory is a 40-strong teaching and research group based in Annecy, France. Its work in the field of mechanical vibrations focuses on the development of multi-physics structures including mechanical and electronic aspects, as well as electromechanical couplings. The laboratory is equipped to design and characterize piezoelectric vibratory devices.
