Nonlinear semi-passive vibration control based on synchronized switch damping with energy transfer between two modes

Abstract : Vibration control based on mechanical energy transfer was recently proposed in a technique called synchronized switch damping with energy transfer (SSDET). In this technique, the mechanical energy, which is extracted from a energy source structure is transfered in order to damp another structure. This paper introduces this technique on a multimode vibrating structure. The energy transfer path is from one mode to another. A threshold is set in the control system for the sake of better damping. Experiments are carried out on an one edge clamped plate and both the harmonic response and the impulse response are considered. Results validate the effectiveness of this technique for multimode vibration control.
