Tóm tắt

PurposeThe paper aims to determine whether the type selection and parameters determination of the compensation are most important for yielding the acceptable or optimized characteristics in design of hydrostatic bearings.Design/methodology/approachThis paper utilizes the equations of flow equilibrium to determine the film thickness or displacement of worktable with respect to the recess pressure.FindingsThe stiffness due to compensation of constant‐flow pump increases monotonically as recess pressure increases. Also, the paper considers which is larger than that due to orifice compensation and capillary compensation at the same recess pressure ratio.Originality/valueThe findings show that the usage range of recess pressure and compensation parameters can be selected to correspond to the smallest gradient in variations of worktable displacement or film thickness.
