A DYNAMIC LOW-FREQUENCY VIBRATION DAMPER FOR BEARINGS OF TURBINE-GENERATOR SETS

摘要

Formulas for calculating the dimensions of a dynamic low-frequency vibration damper are derived. The damper is designed as a circularly curved thin-walled plate. Bench tests demonstrated that the damper effectively reduces the amplitude of vibrations of the bearing of a high-power turbine-generator set in two directions simultaneously.
