Experimental Study on Force Magnification for Vibration Power Generation by using Lever Mechanism

Abstract

The purpose of this research is to expand the output of the vibration power generator. Vibration power generation has been drawing more attention in recent years as it can be used for sensors applied to health monitoring of aged buildings and bridges. Lever mechanism has been adopted in order to apply more force onto reverse-magnetostrictive material for power generation. The natural frequency can be changed by changing leverage ratio so that the applicable frequency band can be adjusted. The experimental machine has been built and frequency response from the acceleration of the vibration to the generated voltage has been obtained. The theoretical vibration power generator has also been analyzed by using software “Creo Simulate”. Experimental and theoretical results have been compared and examined.
