| Summary: | 碩士 === 國立臺灣科技大學 === 機械工程系 === 95 === The purpose of this thesis is to explore the tuned mass absorber on optimization of vibration absorption and power harvesting. First, by driving the equation of motion, the parameters of the main system power were obtained, and they are mass ratio, frequency ratio, and damping ratio. And by changing the parameters, the changing tendency of the main system power were then gained. Afterward, utilizing the relative amplitude of the absorber and main system to drive vibration power harvesting by damping, and define power harvesting index to analyze the effects. Next, we analyzed the optimization in order to compare the absorptions and power harvesting effects of the absorbers for ever parameters in different driving frequencies. Besides, the optimal design values of the absorption and power harvesting effects are also presented by the way of numerical results. In the end of the paper, some suggestions of future study are also provided.
