We report experimental observation of a window of periodic oscillations within the chaotic oscillations of a finite piezoelectric structure electrically forced with a frequency equal to – or close to – a normal mode. Continuously sampled spectra of the oscillation as the level of the driving voltage is increased, reveal the general behaviour of the system as well as features that suggest that the periodic oscillation forms a distinct island within the chaotic region in the parameter space. A period-doubling sequence routing to chaotic oscillations is also observed.

Abstract
We report experimental observation of a window of periodic oscillations within the chaotic oscillations of a finite piezoelectric structure electrically forced with a frequency equal to – or close to – a normal mode. Continuously sampled spectra of the oscillation as the level of the driving voltage is increased, reveal the general behaviour of the system as well as features that suggest that the periodic oscillation forms a distinct island within the chaotic region in the parameter space. A period-doubling sequence routing to chaotic oscillations is also observed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
