Abstract:
The recessed hydrostatic bearing without axial grooves is such a
bearing that makes good use of the dynamic effects on the axial
and circumferential lands in order in order to improve the load
capacity of the bearing. In this paper the programming of the
hydrostatic bearing with any number of recesses is discussed.
For the analysis and calculation of the bearing, the Reynolds'
equation is directly solved by the Finite Difference Method with
imequal steps which is one of the much more general numerical
formulation. The Complex Method is applied in the optimum
design. The total power dissipation/load capacity is regarded as
an objective function. In order to make the optimum design
available for use, a series of technical approaches are applied
to save computer time, such as higher and/or lower accuracy
iteration technique, automatic selection of the superrelaxation
factors. The computer program written in FORTRAN 77 for the
optimum design is worked out and can be run on the
microcomputers such as IBM-PC, MC 68000 which is specially
suitable to the conditions in our county.
