Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1965 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: This design handbook presents data and methods for use in analyzing the dynamical performance of a rotor supported in fluid film type bearings. The data are given in form of design charts covering: (1) The dynamic bearing coefficients; (2) The onset of hydrodynamic instability; and (3) The critical speeds and the unbalance response of a simple rotor-bearing system. The design charts are in dimensionless form and cover a wide range of bearing geometries and operating conditions. Several different types of fluid film bearings are considered together with various forms of lubrication.

Available in PDF, EPUB and Kindle. Book excerpt: This Part IV of the Final Report presents design data for the stiffness characteristics of ball bearings for use in analyzing the dynamical performance of a rotor. The dynamic characteristics of fluid film bearings are given in Part III which also gives the methods for performing the analysis of the rotor-bearing system. Design data are presented for the extra-light and light group of deep-grooved and angular contact bearings undergoing either a pure radial load, pure axial load, or combined radial load with axial preload. The data are given in graphical form and cover both radial stiffness and load- carrying capacity. A nominal damping value for ball bearings, obtained from experimentation, is suggested. Some of the general guide rules for the selection of ball bearings are given. These are concerned with fatigue life, limiting speeds, design, and lubrication. Safe load levels are indicated.

Available in PDF, EPUB and Kindle. Book excerpt: This report is an update of the original Part IV of the Rotor-bearing Dynamics Design Technology Series, AFAPL-TR-65-45 (Parts I through X). A Computer program is given for preparation of ball bearing stiffness data input for rotordynamic response programs. The complete stiffness matrix is calculated including centrifugal effects. Considerations such as elastohydrodynamic and cage effects are not included since they have little influence on the calculation of ball bearing stiffness. The resulting program is reasonably small and easy to use. Lastly, the stiffness data included in the original Part IV have been updated and are included in appendices.
