DTIC ADA094087: Rotor-Bearing Dynamics Technology Design Guide. Part 8. A computerized Data Retrieval System for Fluid Film Bearings

This report describes a computerized data storage retrieval system for the static and dynamic characteristics of fluid film bearings. The procedure combines asymptotic power law extrapolation outside the stored data range with smooth interpolation within the data table. Thirty-one data tables have been prepared and installed in the system. The procedure allows addition of new data tables in the future. The retrieval software allows the user to list the data content in either the dimensional or the dimensionless form or to generate data lines in the sequence and format directly usable as input to the rotordynamics software described. Inertia, compliance and damping effects of the pedestal can be included in the retrieval dynamic characteristics of each bearing.
