Non-linear vibrations :
This theme revolves around 'structures' in the broadest sense, whether academic or industrial, and covers multidisciplinary applications in the fields of dynamics, contacts, acoustics, electromechanics and thermics. The challenge is to model and predict the often highly non-linear behaviour of these structures or machines. One of the aims is to propose advanced numerical modelling methods that reduce the cost of calculations while ensuring or even improving robustness. These methods may address one or more of the following points: multi-physics, multi-scale aspects, geometric and/or behavioural non-linearities, localised non-linearities, changes in boundary conditions, etc.

• Rotating systems, Rotor dynamics
• Friction-induced vibrations, localized nonlinearities
• Parametric analysis of bifurcations - Exploiting non-linearities


Energy control, recovery and exchange :
In the fields of transport, energy and health, embedded systems are faced with the challenge of energy autonomy, the challenge of adaptability and the need to increase performance while ensuring safe operation. From electroactive materials to structures, our research activities focus on the development of dedicated electromechanical transducers (piezoelectric sensors, PMA active magnetic bearings, flexible generators, etc.), on the implementation of innovative control techniques (non-linear, dual, hybrid, etc.) and on hybridisation for applications in vibration control, rotating machine control or mechanical energy recovery in order to meet the scientific and technological challenges of 'smart structures'. Our research also aims to develop new hybrid systems by optimising the synergies resulting from the combination of control laws, integrated or distributed electromechanical transducers and a specific mechanical design.
