碩士 === 國立高雄應用科技大學 === 機械與精密工程研究所 === 100 === The subject of this study is to build a power generator system by piezoelectric cantilever beam. In order to understand the stress/strain distribution and the natural vibration modes of the piezoelectric cantilever beam, the finite element analysis software, ANSYS, was used to analysis static analysis and modal analysis of the piezoelectric cantilever beam. In the experiment procedure, magnets were attached to the axis of the electric fan and free side of the piezoelectric cantilever beam. A direct circuit electric fan was used to rotate the axis of the power generator system. The distance between the magnets on the axis and the piezoelectric cantilever beam was varied to investigate the power generation capacity of the system. The power generator system with four piezoelectric cantilever beams sets on the bike. We can get the output electricity of 22.7V under the circumstances: wheel speed on 950 rpm, magnets arranged in suction and exclusion, 17 mm for distance of magnets on axis and piezoelectric cantilever beam.
