Study on the Forced Torsional Vibration Response of Multiple Rotating Blades with Underplatform Dampers

open access: yesAerospace, 2023
Underplatform dampers (UPDs), a type of dry friction damper, are commonly used for vibration reduction of turbine blades. This study investigated the effect of UPDs on the forced torsional vibration response of turbine blades within a multi-blade system.
