Analysis of Whirl Speed of Rotor-bearing System Supported on Fluid Film Bearing

This proposal outlines the background of the project “Analysis of whirl speeds for rotor bearing systems supported on fluid film bearings”. Most of high speed rotating machinery such as turbines and rotary compressor use both journal and thrust bearing configuration. However, in practice, only journal bearings play a significant factor in rotor whirling and vibration. When bearing fails or shows sign of distress, it is important for the engineer to recognize and make corrective adjustment before catastrophic failure of the entire machinery occurs. This explain the purpose of this study which is to provide analysis of whirl speeds for rotor bearing systems supported on fluid film bearings. Further details are explained in Chapter 1.
