Abstract

Journal of Vibration and Control, Ahead of Print.
Elastic ring squeeze film dampers (ERSFDs) are widely used in high-speed aero-engine rotor systems for multi-critical speed vibration control. This study proposes a time-efficient fluid-structure interaction framework combining elastic ring deformation ...
