Abstract
비회전 조건에서 공기로 윤활되는 하이브리드 저널 베어링-회전축 시스템의 특성을 규명하기 위한 실험을 진행하였다. 회전축 삽입 유, 무의 조건으로 실험을 진행하였으며, 압축성 유체를 외부가압 할 때 공급 압력에 따른 유량을 측정하여 이용하였다. 실험 결과와 해석 결과를 비교하여 통해 회전축 시스템의 비회전 특성에 대해 연구하였다.
The current work measures bearing characteristics of a test rotor supported on two hybrid journal bearings, lubricated with ambient air, at a non-rotating condition. Various bearing performance characteristics are recorded while increasing air pressure into the test bearings. The measured data correlate well with predictions.
