碩士 === 國立高雄應用科技大學 === 機械與精密工程研究所 === 98 === In this study, we use a piezoelectric cantilever beam as the main components of generation to research a torsional generator system. We also use finite element analysis software ANSYS to analyze the stress and strain of the system. The driving source of the torsional generator system is a stepping motor. We use Keli C to compile the driving program, and burn the program into the 8051 chip by ISP-Pgm3v0. The stepping motor control card will send the signal to 8051 chip to control the positive and negative rotation speed, and frequency of stepping motor. In Energy extraction, we transfer DC signal to AC signal by full bridge rectifier circuit. The voltage is 11.4 volts when the torsion angle is 9 degrees, and the piezoelectric cantilever tip displacement is 1.04 mm . Finally, we obtain the average voltage is 6.5 volts by applying the torsional generator to a mouse system.
