Optimization Design Analysis of the Eccentric Rotor System with SFD

Abstract: Background Squeeze Film Damper plays an important role in enhancing the dynamic stability of the rotor and damping rotor vibrations and transmitted forces when traversing critical speeds. Depending on how SFD is designed, SFD can reduce the vibration and transmission forces of the rotating system and it can have the opposite effect. In particular, depending on how the single eccentric rotor system with SFD is mathematically accurately modeled and optimize, the stability of the single eccentric rotor system wit… Show more

“…In [18] is studied the instability induced by the airflow excitation force (Alford force) in a Jeffcott rotor and optimized the stiffness of the supports and shaft diameters to significantly improve the stability of the rotor system. Last, in [19] is employed a genetic optimization method to optimize the design of an eccentric rotor system with a squeeze film damper, resulting in a 15% improvement in system stability and reduced vibration amplitude.…”
