Rotordynamic and Journal Bearing Analysis Course Objectives:

• Understand the differences in rotor behavior when machine rotors are supported by different bearing types, rolling element bearings and fluid-film bearings
• Understand journal bearing design theory and how it applies to vibration troubleshooting
• Be able to apply the basic principles of rotor-bearing dynamics to vibration diagnosis
• Be able to apply vibration theory and techniques, including measurement and interpretation of multi-channel spectral results such as frequency response functions, phase and coherence
• Be able to understand and perform signal analysis, including understanding of frequency and time domain processing, including orbits, shaft centerline plots, load path plots and their limitations
• Utilize multiple data formats including spectra, full-spectra, waterfall, cascade, and bode in vibration diagnosis of journal bearing turbomachinery
• Understand the currently available measurement techniques for contact and non-contact measurements on rotating machines, reciprocating machines, and structures
• Be able to apply the proper sensor technology based on many different applications
• Diagnose typical malfunctions including but not limited to unbalance, misalignment, cocked bearing, whirl, whip, loss of lubrication, aerodynamic and/or hydraulic instabilities, worn bearing and resonance.
• Be able to determine the natural frequencies, mode shapes and damping of systems, components and assemblies

Note: All labs will be split between solving for an unknown malfunction and practice problems.While students are in lecture, Red Wolf Staff will induce at least one malfunction into the lab rotor and the students will be given time to determine the issue and correct it.

Malfunctions may vary from sensor or other hardware and software issues to problems with the rotor and/or its bearings or lubrication.

Practice problems will include topics like lubricant selection, proper clearance determination, alarm calculations, natural frequency calculations, balance corrections, etc... There will also be general knowledge practice questions.
