Composite vibration damping system
TLDR
In this paper, a distributed distribution of vibration damping devices is proposed to minimize overall vibration without the introduction of energy from an external source, without the need of external power supply.Abstract:
Plural vibration damping devices transmit to and receive energy from a distributor that is programmed to either dissipate the vibration induced energy produced by the devices or redistribute the vibration induced energy produced by some of the devices to minimize overall vibration without introduction of energy from an external source.read more
