Résumé  :

Flow-induced vibrations (FIV) usually lead to self-excited oscillations that can cause relevant impact on the structural lifespan. Hence, the search for alternatives for passive suppression is of interest for both the academic and the technological communities. Sometimes, linear absorbers like the tuned mass dampers are not effective for suppressing FIV. In this talk, the use of nonlinear energy sinks (NESs) is discussed as alternatives for passive suppression of three FIV phenomena, namely vortex-induced vibrations (VIV), galloping and vibrations due to the internal flow in pipes discharging fluid. Numerical and experimental results will be presented and discussed.
