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 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 کاملReliability of Shallow Foundations Designed Against Bearing Failure Using LRFD
There is a growing interest world-wide in the development of a rational reliability-based geotechnical design code. The reason for this interest is a least two-fold; first of all, geotechnical engineers face uncertainties which are commonly significantly larger than those faced in other fields of engineering and so there is a need to properly characterize and deal with this uncertainty. Secondl...
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 کاملInterface pressure profile analysis for patellar tendon-bearing socket and hydrostatic socket.
Conventionally, patellar tendon-bearing (PTB) sockets, which need high dexterity of prosthetist, are widely used. Lack of chartered and experienced prosthetist has often led to painful experience of wearing prosthesis and this will in turn deter the patients to wear the prosthesis, which will further aggravate stump shrinkage. Thus, the hydrostatic socket which demands relatively lower level of...
