Dynamic modeling analysis of the gas turbine engine rotor system with SFD

Abstract: Purpose As a core rotating component of power machinery and working machinery, the rotor system is widely used in the fields of machinery, electric power and aviation. When the system operates at high speed, the system stability is of great importance. To enhance the system stability, squeeze film damper (SFD) is being installed in the rotor system to alleviate vibration. The purpose of this paper is to first classify the rotor system into two types, the dual rotor system and the single rotor system, and to co… Show more

“…Wu et al (2011) analyzed the contact stress and load distribution between roller elements and raceways using Hertz theory and established the calculation method for bending moment on the bearing end faces. A dynamic model of the bearing rotor system was created in consideration of the dynamic characteristics of the oil film damper by combining lubrication theory and rotor dynamics (Ri et al , 2021a, 2022).…”
