8. Balancing
Balancing is a procedure by which the mass distribution of a rotor is adjusted to
ensure that the vibration and/or forces at the bearings at a frequency
corresponding to service speed are within specified limits.
From Main menu select Balancing .
With the Balancing application in VIBER X5 MkIII™ you
can perform 1 or 2 plane balancing. This application is
optional.
Rotor unbalance can be caused by design, material,
manufacturing and assembly. Every rotor has an individual
unbalance distribution along its length, even in a series
production.
