Power-efficient active structural vibration control by twin rotor dampers

In this comprehensive study, the basic design of the twin rotor damper is described, characteristics analyzed, appropriate controls developed, and useful applications given. It is shown that the proposed device is an eective device for control of structural vibrations. Furthermore, it is demonstrated that the new damper is very ecient compared to conventional active mass dampers. Moreover, the study presents results of numerical simulations of example implementations as well as of experimental tests that verify the functioning of the twin rotor damper.
