    • Solving Magnetodynamic Problems via Normal Form Method 
      Article dans une revue avec comité de lecture
      UGWUANYI, Nnaemeka S.; ccCLENET, Stephane; ccKESTELYN, Xavier; ccTHOMAS, Olivier (Institute of Electrical and Electronics Engineers (IEEE), 2022-03)
      Closed-form formulations are difficult to find when the material behavior law is nonlinear. A linear approximation, on the other hand, has a very narrow range of validity. In this communication, the Normal Form (NF) method ...
    • The reduction of operational amplifier electrical outputs to improve piezoelectric shunts with negative capacitance 
      Article dans une revue avec comité de lecture
      BERARDENGO, Marta; MANZONI, Stefano; ccTHOMAS, Olivier; DRAGO, L.; MARELLI, Stefano; VANALI, Marcello; ccGIRAUD-AUDINE, Christophe (Elsevier BV, 2021-08)
      One way to enhance the performance of vibration control with piezoelectric shunt is to use a negative capacitance in the shunt circuit. This component is very effective and pro- vides good results in terms of attenuation ...
    • Dynamic stability of centrifugal pendulum vibration absorbers allowing a rotational mobility 
      Article dans une revue avec comité de lecture
      MAHE, V.; RENAULT, Alexandre; GROLET, Aurélien; ccTHOMAS, Olivier; MAHE, Hervé (Elsevier BV, 2022-01)
      Centrifugal pendulum vibration absorbers (CPVA) are used in the automobile industry to reduce the vibrations of the transmission system. These passive devices are made of several masses oscillating along a given trajectory ...
    • Very large amplitude vibrations of flexible structures: Experimental identification and validation of a quadratic drag damping model 
      Article dans une revue avec comité de lecture
      COLIN, Mathieu; ccTHOMAS, Olivier; GRONDEL, Sébastien; CATTAN, Éric (Elsevier BV, 2020-08)
      This article presents a theoretical, numerical and experimental study of resonant structures undergoing very large amplitude vibrations. The purpose of this work is to validate a model for the damping due to the action of ...
    • On the dynamic stability and efficiency of centrifugal pendulum vibration absorbers with rotating pendulums 
      Article dans une revue avec comité de lecture
      MAHÉ, V.; RENAULT, Alexandre; GROLET, Aurélien; MAHÉ, Hervé; ccTHOMAS, Olivier (Elsevier BV, 2022-10)
      The automotive industry uses centrifugal pendulum vibration absorbers (CPVAs) to reduce vibrations of the transmission system. These passive devices are made of several masses oscillating along a given path relative to a ...
    • Subharmonic centrifugal pendulum vibration absorbers allowing a rotational mobility 
      Article dans une revue avec comité de lecture
      MAHE, V.; RENAULT, Alexandre; GROLET, Aurélien; MAHE, Hervé; ccTHOMAS, Olivier (Elsevier BV, 2022-09)
      Rotating machines are often subjected to fluctuating torques, leading to vibrations of the rotor and finally to premature fatigue and noise pollution. This work addresses a new design of centrifugal pendulum vibration ...
    • A normal form-based power system out-of-step protection 
      Article dans une revue avec comité de lecture
      UGWUANYI, Nnaemeka Sunday; ccKESTELYN, Xavier; ccTHOMAS, Olivier; ccMARINESCU, Bogdan; WANG, Bin (Elsevier BV, 2022-07)
      This paper proposes a new system-level application for monitoring out-of-step (OOS) events in power systems. As already known, amplitude-dependent frequency shift is a nonlinear phenomenon of electromechanical oscillations ...
