Prospects for the Application of Compound Dampers in Turbomachinery Rotors

Abstract

Abstract—The research carried out in the article is directed at reducing vibrations and increasing the fatigue life of turbomachinery elements. Prospective designs for compound dampers of rotor supports and major ways to improve their parameters are discussed. The characteristics of a compound damper and other types of squeeze-film dampers are compared. It is shown that the damping coefficient of a compound damper is 35% higher than that of a short hydrodynamic damper (HDD) of the same dimensions.
