GREEN'S FUNCTIONS FOR JOURNAL BEARINGS,

Abstract

The Green's Functions are given as the sum of a closed form function and a Fourier Series. The coefficients of the Fourier Series are given as functions of peripheral source location and journal eccentricity. With these data it is shown how the Green's Function for any L/D and source offset can be generated. Data assumes full 360 degree journal bearings but transformations are given for generating the Green's Functions for 180 degree bearings as well. The data given is applicable to both compressible and incompressible fluids. By the use of Green's Function the bearing problem is reduced from one of solving partial differential equations to one of simple integrations. The computer programming for integration is considerably simpler than that for differentiation. This simplicity enables designers not deeply versed in field equations and their convergence to perform their own analysis with minimum restrictions on geometry. (Author)
