Damping for Increased Stability

SFD versus ISFD design

Damping decreases vibrations by removing energy through resistance to motion. For rotating equipment, damping is necessary to control vibrations and prevent them from damaging the rotor, bearings or other components in the machine.

Using an engineered damper can increase stability, reduce rotor response, increase the separation margin between operating speed and critical speeds, reduce forces transmitted from rotor to ground, reduce pedestal vibrations, reduce bearing wear, and decrease sensitivity to changes to the rotor, such as material buildup on a rotating component.
