本研究旨在設計雙懸臂樑吸振器並探討其吸振與功率回收，最後進行最佳化研究。文中首先推導具吸振器之主系統的運動方程式，並定義吸振指標。經數值分析了解影響吸振之參數有質量比、頻率比、阻尼係數與阻尼器連接位置。吾人藉由參數變化分析，可掌握主系統功率之變化趨勢，續利用吸振系統中雙懸臂樑之相對速度推導阻尼回收振能功率，並定義振能回收指標藉以分析振能回收效應。在最佳化分析中，比較不同驅動頻寬之下，各參數對吸振器之吸振與功率回收效應的趨勢走向。並依照兩指標之定義，提出兼具吸振效應與功率回收效應之最佳設計參數値，提供使用者一設計參考。

The purpose of this thesis is to explore the tuned mass absorber on optimization of vibration absorption and vibration power harvesting. First, by deriving the equations of motion, the parameters of the main system power are obtained, and they are mass ratio, frequency ratio, damping coefficient, and the location of damper that connects the cantilever beams. Via changing the parameters, the vibration absorption of the main system were then realized. Afterwards, the vibration power harvesting through absorber’s damping is defined and analyzed. Next, we investigated the optimization process between vibration absorption and vibration power harvesting for various frequency ranges. Numerical results showed the applicability of the devise and presented. Some suggestions of for the vibration industry.
