Abstract

Vibration exchange between a master linear oscillator and a slave Nonlinear Energy Sink (NES) under harmonics excitation by means of several resonance capture is investigated and commented upon. The importance of higher frequencies by introducing the concept of the relative mode is pinpointed. A fast and special iterative technique and then the more general form of it is introduced in order to evaluate the system unknowns. Finally, the effect of the correct resonance paring on detecting the actual system behavior is illustrated by an example.
