Abstract

Journal of Vibration and Control, Ahead of Print.
Considering the limited modal damping performance and reduced robustness of conventional linear dampers, such as multiple tuned mass dampers (MTMDs) employed in piezo-driven nanopositioning stages, this paper proposes a lightweight elastic vibro-impact ...
