Influence Research of Cavity Shapes on Temperature Field of Multi- pad Hydrostatic Thrust Bearing
In order to compute the thermal deformation of the hydrostatic thrust bearing in the heavy type CNC equipments, a numerical research concerning temperature field of multi-pad hydrostatic thrust bearing having sector cavity, rectangular cavity, Ishaped cavity and ellipse cavity is described. Three-dimensional temperature field of gap fluid between the rotation worktable and the base has been sim...
متن کاملFlow Criterion Research on Fluid in Hydrostatic Bearing from Laminar to Turbulent Transition
The multipad circular guide hydrostatic bearing of heavy-duty CNC machine is taken as the research object. Based on the lubrication properties of the heavy hydrostatic bearing, viscosity-temperature equation of interstitial fluid is established in various viscosities. In accordance with factory actual production, the fluid critical from laminar to turbulent is calculated by finite volume method...
متن کاملAnalysis of Temperature Effect on the Lubricating State of Hydrostatic Bearing
Setting the effect of oil states (sufficient state and deficient state) on temperature field distribution and temperature rise of heavy hydrostatic bearing as the starting point, simulation research is conducted with the FLUENT 6.5, which is popular in current field of scientific research all over the world. The results show that the temperature of heavy hydrostatic bearing has a linearly incre...
متن کاملIn vitro models for glaucoma research: effects of hydrostatic pressure.
PURPOSE The response of cells (e.g., optic nerve head [ONH] cells) to mechanical stress is important in glaucoma. Studies have reported the biological effects of hydrostatic pressure on ONH cells cultured on a rigid substrate. An apparatus, designed to independently vary hydrostatic pressure and gas tension (including oxygen tension) in culture medium, was used to evaluate the effects of pressu...
