Abstract:Vibration dynamic absorber is in use to reduce machinery vibrations. This paper presents a novel idea for using the mass-spring absorber as an energy harvester. The aim is to tune the absorber to cancel the machine vibration and produce maximum vibration of the absorber mass to act as an energy harvester. The main vibrating system is damped and assumed as a SDOF. A new frequency is defined called harvesting frequency at which the amplitude of the absorber mass vibration is maximum. It is shown that his frequen… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
