A computer program for IC engine crankshaft main bearings wear diagrams

Abstract

© 2018 Institute of Physics Publishing. All rights reserved. IC engine crankshaft bearings are amongst the most loaded parts of the engine. Forces, acting on crankshaft bearings are changed very intensively during the engine operating cycle. Therefore, it would be very useful to have a visual representation of the bearings wear. For that purpose, a computer program has been developed to generate theoretical wear diagrams for all the crankshaft bearings of the engine. Theoretical wear diagrams provide a picture of the bearing material wear distribution resulting from the bearing load. The bearing load calculations used in the program are based on a statically indeterminate method. The description of the program, followed by some illustrations of its application, has been given in the paper.
