원형 슬롯 레스트릭터를 갖는 외부 가압 공기 저널 베어링의 소음 및 진동 특성

다국어 초록 (Multilingual Abstract)

The purpose of the present paper is to investigate the noise and vibration characteristics of externally<br/>
pressurized air journal bearings with a circular slot restrictor. To do this, the nonlinear transient analysis<br/>
including rotor imbalance was performed for a rotor-bearing system. The effects of radial clearance and the<br/>
width of the bearing and mass eccentricity of the rotor on the noise and vibration characteristics of the bearing<br/>
are also examined. The results show that the noise and vibration of the rotor-bearing system first increase up<br/>
to critical speed of the system, and then decrease up to instability threshold speed of the system as the<br/>
rotational speed of the rotor increases, and the noise of the bearing is markedly influenced by the mass<br/>
eccentricity of the rotor and the radial clearance and the width of the bearing.
