Numerical Simulation of the Effects of Recess Depth on Dynamic Effect of Hydrostatic Thrust Bearing

This work describes a numerical simulation concerning dynamic effect of multi-pad hydrostatic thrust bearing having different recess depth in order to solve the loading capacity of the hydrostatic thrust bearing. Threedimensional pressure field of gap fluid between the rotation worktable and the base has been computed by using the Finite Volume Method. This study theoretically analyzes the influence of recess depth on dynamic effect of the bearing according to the Computational Fluid Dynamics and lubricating theory, and the simulation results indicate that an improved characteristic will be affected by recess depth easily. Through this method, the optimal loading capacity of such products can be achieved.
