Experimental investigation of colored noise in stochastic resonance of a bistable beam

Journal Article (Journal Article)

This paper describes an experimental investigation of stochastic resonance in a bistable, composite beam excited by colored noise. Experimental results for average up-crossing period, spectral power amplification (SPA), and signal-to-noise ratio (SNR) are compared with analytical methods for underdamped systems. These analytical methods include expressions developed from Kramers, Melnikov, and two-state theory. The effect of a modal mass on the analytical expressions is explored. Finally, an alternative approach for calculating the effect of a colored noise spectrum on the SPA and SNR of underdamped systems is proposed. © 2013 Elsevier B.V. All rights reserved.
