A Study on the Analysis of Oil Film in Stern Tube Bearing for Propulsion Shaft of the Ship

선박 추진축계 선미관 베어링 유막 해석에 관한 연구

With an increase in the size and power rate of ship, the stern tube bearing has become subject to severer operation conditions. Particularly it is expected to be exposed to extremely so severe lubrication conditions during low rotational operation that there is strong demand for clarifying the oil film characteristics of the stern tube bearing at the design stage with accuracy. So in this study, we conducted an analysis of the stern tube bearing characteristics taking arbitrary three-dimensional deflection of the shaft into consideration.
