Static, Couple, and Dynamic Unbalance

 · Static Unbalance occurs when the unbalance is distributed equally around the center of gravity and is on the same side of the rotor. The Principal Inertia Axis is parallel to the rotating centerline. If a rotor was put on two knife edges the unbalance would always fall to the bottom. Static unbalance can be corrected in one plane (Figure 1).

BALANCING BASIC PART I

7 A combination of static and couple unbalance fully specifies all the unbalance which exists in a rotor. Specifying unbalance in this manner requires three individual correction mass. DYNAMIC UNBALANCE DYNAMIC UNBALANCE - that condition of unbalance for which the central principal axis is not ...

Balancing of Rigid Rotating Systems

Static unbalance can be balanced by balancing the centrifugal force alone. The above rotor can be balanced by adding the counter mass (m c ) of equal weight as of unbalanced mass (m u ) at an equal radius from the axis of rotation at 180^{o} in the same plane perpendicular to the axis of rotation that contains the unbalanced mass (dark blue colour represents the counter mass …
