Optimum Design of the Recessed Hydrostatic Bearing without Axial Grooves

The optimum design of the hydrostatic bearing with any number of recesses is studied. For the analysis and calculation of such kind of bearing the Reynolds' equation is directly solved by the finite differential method with inequal steps. The complex method is applied to the optimum design in which the total power loss per unit load capacity is regarded as an objective function. In order to make the optimum program more available for use, a series of technical approaches, e. g. higher and/or lower accuracy iteration technique, are employed in saving computer time. On examination of some practical examples, it has been shown that this software package is available, reliable and high efficient so as to be provided directly for designers.
