dc.description.abstract마이크로 가스터빈에 적용되는 공기포일저널베어링의 구조강성 및 감쇠계수를 측정하였다. 실험 베어링에 부가된 정적 하중에 따른 범프 포일의 변형량으로부터 얻은 국부 이력곡선을 이용하여 강성 및 에너지 소산 계수를 추정하였다. 측정된 포일 베어링의 구조적 특성은 베어링에 가해진 정적 예압에 크게 영향을 받는 것을 알 수 있었다.-
dc.description.abstractThe present work identifies structural stiffnesses and damping coefficients in air foil journal bearings for micro gas turbines. The local hysteresis loops from the applied static loads and measured bearing deflections while increasing preloads on the test bearing allow direct estimation of stiffness and energy dissipation parameters. The identified parameters show a notable effect of the applied preload on the structural coefficients of the test foil bearings.-
