本研究主旨在於採用由壓電材料所構成之三層樑搭配回收電路形成一振能回收吸振器，探討吸振及振能回收兩功能間之相互影響關係，並藉由調配系統參數使吸振器可兼顧吸振與振能回收之功能。其概念是利用壓電材料之力電耦合特性，吸收主結構之振動能量並轉換為電能，再將回收所得之能量加以運用。
一般傳統的吸振器，於設計上大多僅考慮其吸振效果，而所吸收到的能量往往以聲、熱，或其他動能等形式消散掉，實為之可惜；因此，本文運用壓電材料之力電耦合特性，將吸收所得之振動能量轉換為電能並回收利用，以響應環保概念，並探討吸振與振能回收兩功能間之相互影響關係。此外，吸振器之吸振與振能回收效能會受設計參數影響，因此本文制定吸振指標與振能回收指標，並藉由改變參數來探討兩指標之間的變化情形，並將結果整理歸納以供使用者設計參考。最後本研究將製作壓電樑吸振器之實體模型，輔以實驗驗證其振能回收之效能，以證實理論模擬之正確性及可信度。

In this thesis, the absorption and power harvesting characteristic of vibration absorber with PZT is presented. The main ideal of this thesis is to use the characteristics of electro-mechanical coupling in piezoelectric materials, and transform the absorption mechanical energy to electric energy. A vibration absorption system is modeled and the index of absorption and power harvesting is derived. The vibration absorption model is an Euler-Bernoulli beam with PZT bounded on its both surfaces and shunted by a resistor circuit as power harvesting system. Use Assume mode method and separation variable method to derive the Lagrange equation of motion of the system. Absorption index and power harvesting index is derived to characterize the design parameters of the system. Via changing the parameters of the lump mass ratio, DVA mass ratio and resistance to discuss the variability between absorption index and power harvesting index. Finally, this thesis will construct a reality model to verify the vibration absorption energy efficient in simulation result by experiment.
