Review on Vibration Problems in Turbomachinery
Abstract: Vibration suppression of turbomachinery is an important engineering problem. Vibration caused by mass imbalance is a common problem in rotating the turbomachinery systems. Imbalance occurs if the principal axis of inertia of the rotor is not coincident with its geometric axis. Higher speeds cause much greater centrifugal imbalance forces, and the current trend of rotating equipment toward higher power density clearly leads to higher operational speeds. In this paper, a …
