Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
In order to accurately analyze conditions of a large two-stroke diesel engine main bearing lubrication, the finite element method and nonlinear multi-body dynamics were combined. Using of AVL Excite software, the elastohydrodynamic (EHD) coupling analysis model were established for main bearing lubrication. The main bearing vertical load, orbital path and minimum oil film thickness were explored. The minimum oil film thickness and power consumption of No.2 bearing were analyzed with the different bearing clearances. The results show that No.2, No.3, No.5 and No.6 main bearing force appear three peaks in a working cycle, the maximum force reached 1400kN approximately. Maximum force is the No.2 main bearing, for 1518kN; and minimum oil film thickness is 4.73μm. No.2 main bearing lubrication is slightly worse.
