Abstract
In this study a 3-D finite element analysis for cantilever plate structure excited by giving unit deflection at free end is presented. Finite Element Modeling based on ANSYS12.0 package using modal analysis and harmonic analysis is used in this study for cantilever plate structure by patch type of piezoelectric plates of PZT-5H4E as a piezo material and steel as a substrate material for Cantilever Beam. This study aims to investigate the influence of different geometry parameters like, length and width & position of piezo patches on voltage generation & try to find out optimal geometrical dimensions of piezoelectric beam for maximum energy harvesting. ANSYS-12.0 is used as optimization tool. Here the basic modeling with an equivalent circuit is done initially by considering some specific dimensions of beam. Then simulation of the same is done by varying different geometrical parameters where effect of change in length of piezo patch is analyzed first .The second affecting parameter considered is change in Width of piezo patch and last one is the position of piezo patch along the length of beam is analyzed, where output is measured in turn of voltage generated. This study aims to investigate the Optimum placement of piezoelectric actuators in a cantilever beam for maximum energy harvesting.
