Vibration Control of a Sealed and Pressurized Squeeze Film Damper Supported Rotor

가압 밀봉된 스퀴즈 필름 댐퍼로 지지된 로터의 진동제어

The vibration of rotors in high speed sometimes leads to system failure or reduces the system life, and has a direct connection with stability. In this paper, the system's modelling was conducted in experimentally and the controller was designed to reduce the vibration due to the rotor unbalance using Squeeze Film Damper(SFD). SFD vibration control was achieved in constant rotating speed based on the controller designed. the control was confirmed working quite well in terms of both numerical simulation and experiment.
