本文以壓電懸臂樑做為發電之主要元件,利用轉軸與壓電片上磁鐵之磁力,驅使壓電片產生變形,研究壓電懸臂樑之發電效應。文中利用有限元素分析軟體ANSYS對壓電懸臂樑進行靜態及模態分析,以瞭解壓電懸臂樑之應力、應變分佈及自然振動模態。
實驗中,將磁鐵黏貼於風扇和壓電懸臂樑的自由端,並以直流風扇作為轉軸之驅動源,接著調整壓電懸臂樑與轉軸間之磁鐵間距,探討其對發電的影響。
研究中將發電系統之壓電懸臂樑增加至四組,裝置於自行車上,當車輪轉速950rpm,磁鐵排列為一吸一斥,磁鐵間距為17mm時,可獲22.7伏特之電壓輸出。

關鍵字:壓電懸臂樑、發電系統、變形
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.

Key: Piezoelectric cantilever beam, Power generator system, Deformation
