Avaliação de uma piezoestrutura engastada-livre para geração e extração de energia

Abstract

This work includes the study of a piezostructure for power generation. The piezostructure comprises an acrylic beam with PZT coupled acrylic beam previously scaled to the structure. ANSYS software was used to scale the PZT length and to simulate piezostructure to obtain the natural frequency to subsequently use the same piezoestrutura to excite and analyze voltage produced. Piezostructure with one tutorial to follow from getting the elasticity coefficient of acrylic beam to the making of piezostructure was built. An experiment where the piezostructure was clamped in an engine to extract the tension produced by piezostructure and later analyzed all data obtained by the simulation and the experiment was prepared.
