Abstract

This study mainly uses the mass conservation algorithm to analyze the influence of the rectangular surface defects, which are distributed on the bearing surface, in terms of the position of surface defects, defect area, defect depth, and defect occupancy rate on the performance of journal bearing at a steady state. The numerical results show that the rectangular surface defects exert an important influence on the load capacity and friction force. Most of the rectangular surface defects are unfavorable for bearing lubrication, although in some cases, the rectangular surface defects can reduce friction force, they can also weaken load capacity and increase coefficient of friction.
