Review on Vibration Problems in Turbomachinery

Priyanka Garg

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 review of the research work performed in real-time active balancing and active vibration control for turbomachinery, as well as the research work on dynamic modeling and analysis techniques of turbomachinery systems, is presented. The basic methodology and a brief assessment of major difficulties and future research needs are also provided.

Keywords: turbomachinery, rotor, vibration, control, aerodynamic loading, structural instabilities, damping, blade.
