This paper analyzes property of vertical misaligned journal bearing, aiming to provide an
approach for efficiently analyzing equivalent supporting point location and carrying capacity …

A flexible structure is applied to improve the lubrication performance of a misaligned journal
bearing. The journal bearing is a representative sliding bearing, and there is damage due to …

The propulsion system is one of the main sources of ship vibrations. A typical propulsion
system consists of an engine, a shaft line and a propeller. In order to estimate the vibration …

The paper presents analysis of displacement of a propulsion system shaft line and a
crankshaft axis caused by temperature of marine, slow-speed main engine. Detailed …

Optimizing the bearing design is an essential step to maintain safe operation and extend the
bearing life. Taguchi method is one of the powerful methods in this direction, which can be …

To address the challenge of accurate lifespan prediction for bearings in different operating
conditions within ship propulsion shaft systems, a two-stage prediction model based on an …

Robust and well-designed rotor-bearing systems ensure safe operation and a high level of
reliability under severe operating conditions. A deviation in the shaft axis with respect to the …
