This study presents a numerical analysis of the static performance of plain journal bearings with inclined wear under external moment loads. The developed model incorporates journal misalignment, inclined wear geometry, and applied moment loads to evaluate bearing characteristics. It determines oil film thickness by considering bearing clearances, journal eccentricities, and misalignment. The model calculates the wear shape based on the wear radius and wear angle. It derives the hydrodynamic pressure field by solving the Reynolds equation using the finite volume method (FVM). By simultaneously satisfying the static force and moment equilibrium equations, the model identifies the equilibrium position of the journal. Results indicate that moment loads increase journal misalignment, which reduces the minimum local oil film thickness, concentrates pressure, and increases power loss. This effect becomes more pronounced at lower static loads. Inclined wear reduces the bearing's load capacity under certain conditions. However, it mitigates the local reduction in oil film thickness caused by the moment load. This mitigation becomes more significant as the wear angle decreases. The wear angle has a minimal impact on power loss. These findings provide new insights into the lubrication and wear behavior of journal bearings subjected to the combined effects of misalignment and moment loading.
