Abstract

Most mechanical vibrations in our environment can be classified as noisy vibrations, since they have no preferred frequency and a spectrum that spreads to the low frequency range. Bistable systems have shown to be a solution to the existing frequency mismatch between the energy source and the harvester device. In this work a parametric study is carried out in order to show the dependence of these improvements with the quality factor Q of a vibrating beam and the different responses when driven by different types of model noise. Specifically, we studied Colored Gaussian Noise instead of the much more common White Gaussian Noise, considered as a reference in most studies.© 2013 Elsevier B.V. All rights reserved.
