dynamic Balancing

Vibration caused by mass imbalance in rotating
machinery is a critical engineering problem. The objective
of balancing is to reduce rotor vibration to a practical
minimum. Reducing rotor vibration generally increases
the service life of the rotating machinery.
Rotating machinery is commonly used in mechanical
systems, including industrial turbo-machinery and gas
turbine engines. Vibration caused by mass imbalance is
a common problem in rotating machinery. Imbalance
occurs if the principal axis of inertia of the rotor is not
coincident with its geometric axis. Higher speeds cause a
much greater centrifugal imbalance force and the current
trend of rotating equipment toward higher power density,
clearly leads to higher operational speeds. Therefore,
vibration control is essential in improving longer bearing
life; and ultimately reducing the number of unscheduled
shutdowns. A great cost savings for high speed pumps,
turbines, compressors and other turbo machinery used in
industries can be realized by removing the imbalance.

Balance is defined as “the process of adding or removing
mass in a plane or planes on a rotor in order to move the
center of gravity towards the axis of rotation”.
