Sažetak
The research and determination of the most suitable theoretical and numerical models available to model the behavior of the lubricant layer in marine radial plain bearings on the newly installed test rig of the University of Split, Faculty of Maritime Studies – PFST is a matter to be resolved. The numerical simulation modeling determines the pressure distribution in the lubricant layer of a radial plain bearing, from which the bearing reaction force and its longitudinal position is obtained by integration. Hence, the goal of this paper is to select a numerical model, which in terms of verification and validation gives the best results by using the MS Excel program “S11BearingsR.xls”, and improve it based on the research results provided by the PFST instrumented test rig. With the experimental verification of the calculated results produced with the program, the values of the bearing reactions and their positions obtained by the calculation can be compared with those that will be produced by the test rig. The numerical model will be obtained by finite differences method, from analytical solution of Reynolds equation and from analytical solution presented in DIN/ISO standards. The obtained results will indicate the selection of the most suitable model.
