Development of A Universal Journal Bearing Test Rig (UJBTR) and ‎Experimental ‎Setup for Oil Film Lubrication Enhancement Regarding ‎Marine Applications.

Abstract

In fact, attaining the final most beneficial target of improving the oil film lubrication for marine ‎‎purposes can be ‎said to have passed through several main stages up till now. The first stage ‎has ‎involved the initial design and ‎construction of the journal bearing test rig marked by ‎sufficient ‎validity for embracing the potential experimental ‎studies. Those studies were ‎concerned with ‎the lubricating oil within the journal bearing [1]. Notwithstanding, the ‎need ‎has then arisen for the ‎second stage which involved carrying out a comprehensive ‎modification and ‎conversion in ‎regard to the journal bearing test rig, aiming at enlarging its ‎capacity and range to endure more ‎‎sophisticated experiments. The modification has involved ‎adding a hydraulic loading system as ‎well as full ‎monitoring process via SCADA system, for ‎the sake of facilitating conducting all ‎potential experiments relating the ‎critical operating ‎factors that might otherwise affect the journal ‎bearing performance. This paper is representing the ‎‎second step in the long uninterrupted series of efforts seeking to ‎outline the results of a ‎proposed research program ‎for marine applications under the title of ‎‎ “Theoretical and ‎‎Experimental Analysis of the Performance of Journal ‎Bearing”. ‎ The program ‎will deal with ‎‎different design and construction aspects of journal bearing, with special ‎‎reference ‎to marine ‎applications. ‎
