2022-07-17Résumé
This study proposes to investigate the effects of dry friction on the behaviour of a parametrically excited nonlinear oscillator using a pendulum as example. A harmonic balance method and time integration simulations are used to respectively compute and validate the solutions of the problem and their stability. The effects of dry friction on the behaviour of the system are discussed.

Article dans une revue avec comité de lectureBERARDENGO, Marta; MANZONI, Stefano; THOMAS, Olivier; DRAGO, L.; MARELLI, Stefano; VANALI, Marcello; GIRAUD-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 ...
