Rotor-Bearing Dynamics Technology Design Guide. Part 1. Flexible Rotor Dynamics

Abstract

This report describes an update of the Air Force computer programs concerned with the dynamics of high speed rotors. The new program, which replaces AFAPL/SFL Programs No. 100, 101, and 117, has the capability to perform a variety of rotordynamics analyses. These analyses include torsional vibration and bending vibration. The bending analyses consist of those for critical speeds, unbalance response, asynchronous response, and rotor stability. In addition, the program incorporates the following: a formulation based on whirl coordinates with an exact bending solution between rotor modelling stations, the capability to utilize a small subset of these stations in much of the calculations, a set of bearing characteristics that depend on rotor speed and vibration frequency and that include anisotropy and damping, and an economical combination of a separate rotor analysis and the characteristics of the bearings. The report includes: an introduction to use of the program as well as a detailed user's manual, an overview of the mathematical basis of the program and a complete presentation of those mathematics.
