Finite element analysis of orifice-compensated multiple hole-entry worn hybrid journal bearing

摘要: This paper presents the analysis of a non-recessed worn hybrid journal bearing with orifice restrictors. Using Newton-Raphson method, FEM is used for solving Reynolds equation governing flow lubricant in clearance space. The performance characteristics are presented wide range wear depth. results computed an orifice-compensated hole-entry configuration uniform distribution holes circumferential direction. show that affects significantly and therefore, due consideration defect should be given accurate prediction over number cycles.
