Abstract

This paper shows a new strong coupling analysis method for calculation of hydrodynamic lubricating film characteristics on the stern-tube-bearing of large-sized ships. The dynamic forces on the propeller shaft in turning conditions were calculated using CFD. Then, the propeller shaft center loci were calculated using dynamic propeller shaft forces, and were compared with the results of measurements of shaft center loci of a full-scale ship, where the results showed approximately good coincidence, thereby the validity of this analysis was confirmed.
