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
• Be able to determine the natural frequencies, mode shapes and damping of systems, components and assemblies
