Based on the theory of Computational Fluid Dynamics (CFD),the oil film lubrication model was built and simulated by FLUENT software.The effects of oil film thickness,inclined angle of pads,position of annular oil groove on load capacity of a new type thrust bearing were analyzed.The results show that the load capacity of the new type thrust bearing is increased with the decrease of the oil film thickness,and the thinner the oil film thickness is,the more remarkable the increasing of bearing capacity.When the oil film thickness is a constant,both the load capacity and peak pressure are increased first and then decreased with the increasing of the inclined angle of pads.The load capacity is increased when the position of annular oil groove moves outward,and the reasonable position of annular oil groove can increase the load capacity of a new type thrust bearing significantly.
