The Determination of the Characteristics of Hydrostatic Bearings through the use of the Electric Analog Field Plotter

A novel geometry optimization approach for multi-recess hydrostatic bearing pad operating in static and low-speed conditions using CFD simulation

“…Loeb [17] introduced a new methodology for estimating optimal proportions of the bearing pad and recess based on electric analog eld plotter. Generalized analytical equations could be used to calculate the bearing performance using read values obtained from graphs, presented in Loeb and Rippel [16].…”

“…A derivation of this may be found in [3]. 5 Equation (71) will reduce to (14) for the spccial case in which p0 2 << 1. To illustrate the error introduced, consider the following bearing, tested in the course of a project which will be the subject of a forthcoming paper [4) on hydrostatic bearings: 4 Bearing and Lubricant Center, General Engineering Laboratory, General Electric Co., Schenectady, N. Y. Assoc.…”

“…The authors' solutions for the square plate bearing with central round hole may be compared to a previous solution of this shape by A. M. Loeb [5]. This geometry, and many others, were solved by an electric analog field plotter.…”

“…This geometry, and many others, were solved by an electric analog field plotter. The load and flow from [5] for a square plate 20 in. on a side, with a one inch diameter center hole, is:…”
