The oil film clearance of hydrostatic workbench directly affects its lubrication performance. The oil film shape is determined by deformation of bearing friction pairs, and is extremely difficult to obtain. This study will indirectly obtain the oil film clearance through the deformation of the bearing friction pair, and the deformation prediction of hydrostatic workbench with double rectangular cavities in heavy type vertical lathe has(been) studied based on ANSYS WORKBENCH, and these are helpful to further investigate oil film shape under the working conditions of high-speed and heavy-load. The oil film clearance test bench was established, and the simulation results were verified, which verified the effectiveness of the proposed numerical simulation method. It can be concluded that with the increase of rotational speed and carrying load, the oil film temperature increases rapidly, the deformation of rotational workbench and base enlarges sharply, the viscosity of lubrication oil declines quickly, oil film becomes thinner immediately, together with bearing friction pairs uneven deformation, and local bearing friction pairs occurs boundary lubrication or dry friction, and then occurs friction failure.

Journal of Applied Fluid Mechanics

The Journal of Applied Fluid Mechanics (JAFM) is an international, peer-reviewed journal which covers a wide range of theoretical, numerical and experimental aspects in fluid mechanics. The emphasis is on the applications in different engineering fields rather than on pure mathematical or physical aspects in fluid mechanics. Although many high quality journals pertaining to different aspects of fluid mechanics presently exist, research in the field is rapidly escalating.
