Tuning of a Nonlinear Energy Sink using multi-stability

Résumé

This work addresses the development of a nonlinear absorber based on the concept of a Nonlinear Energy Sink (NES) under different multi-stable configurations. The potential energy of the system can be written under a potential that possesses two or more stable equilibrium positions separated by saddle points. The study of the dynamics at different time scales leads to the computation of the Slow Invariant Manifold (SIM) where singular points indicate the possible occurrence of Strongly Modulated Responses (SMR). It is shown that, compared to a bi-stable NES, the threshold activation of a multistable NES can be significantly lowered with same dissipation ability.
