Abstract

The effects of sphere dimples on the tribological performances of the journal bearing were investigated. The oil film rupture and reformation positions were obtained using a mass-conservation JFO(Jakobsson, Floberg, Olsson)boundary condition. The influences of the sphere dimples with various distribution forms and geometry parameters on the load-carrying capacity and friction characteristics were investigated. On this basis, parameter optimization of textured sphere dimples was implemented using genetic algorithm. The results show that the optimal dimple angle range and maximum depth can increase load-carrying capacity and decrease friction factor effectively when the eccentricity is small, but the sphere dimple texture is invalid for the decrease of friction factor when the eccentricity is large.
