Reduction of Vibration of Fluid Loaded Plate with Piezoelectric Elements - a Comparison of Analytical, FEM Harmonic Analysis, and Real Results

Abstract

In the present paper, a comparison of analytical calculations, FEM harmonic analysis, and real data from laboratory stand of uid-loaded structure were taken under consideration. Resonant frequencies of the investigated structure were measured using swept sine technique on laboratory stand. Analytical calculations of the rst twelve modes were made and the numerical model was build using the nite element method. Results from real data, analytical calculations, and numerical calculations are comparable.

Evaluation of the Effect of a Step Change in Piezo Actuator Structure on Vibration Reduction Level in Plates

“…Since the works of Dimitriadis, Fuller, and Rogers (1991) these materials have been typically used for beams (Brański, 2013;Ferdek, Kozień, 2013 (Wiciak, 2007;2008; Trojanowski, Wiciak, 2010;Iwański, Wiciak, 2013;Jabłoński, Ozga, 2012). In most cases, a significant reduction of vibration or/and acoustic pressure can be achieved.…”
