Abstract
The main features of suggested model are as follows. Elastic crankshaft rotates in main bearings, bearing supports elastically deform in the linear and the angular directions under action of forces resulted from journals and bearings interaction. The linear and the angular elasticity limits of supports and crankshaft of a particular engine is a subject of FEM study. The model of dynamically loaded bearings considers the misalignment and the angular displacements of journals and mixed lubrication conditions. A new method to obtain hydrodynamic forces as well as moments is described. In addition to the existing bearing performance evaluation criteria, the deviation criteria has been suggested. The model and its modifications have been on-going basis for study and the improvement of several types of diesel locomotive engines. Some of the results of these studies are presented.
