In this work, we consider a MEMS microbeam, and we investigate the experimental response of the device at the third-mode dynamics. By forward and backward sweeping, the data acquired via the laser Doppler vibrometer show the occurrence of a 2:1 internal resonance, where the coupling mode is the fifth. The experimental response is simulated via shooting technique and attractor basins. We focus on the metamorphoses of the basins of attraction scenario induced in the phase space by the activation of the internal resonance.

Abstract
In this work, we consider a MEMS microbeam, and we investigate the experimental response of the device at the third-mode dynamics. By forward and backward sweeping, the data acquired via the laser Doppler vibrometer show the occurrence of a 2:1 internal resonance, where the coupling mode is the fifth. The experimental response is simulated via shooting technique and attractor basins. We focus on the metamorphoses of the basins of attraction scenario induced in the phase space by the activation of the internal resonance.File in questo prodotto:
