N2 - As one kind of main shaft bearings, hydrodynamic journal bearings will have a long lifetime under purely hydrodynamic lubrication regime. However, the bearings are easy to wear when they are in mixed lubrication regime during starting and stopping. In this paper, a new method is presented for wear analysis of the hydrodynamic journal bearings, which is based on abrasive wear model. An equation is formulated for predicting the specific wear rate of the bearing material which as a function of the wear depth. Finally, the wear region and wear volume of journal bearings for a stripped-down single cylinder engine during start-up and coast-down are calculated by the proposed method, and then results are compared with those based on footprint model. The analysis results show that abrasive wear model is better than footprint model, since its results are closer to experimental investigation results than those of footprint model.
