Vibration Level 3 Outline

Case Histories and Round Table Discussion

Each of the following topics will include analysis and round table discussion noting successes and challenges from individual advanced cases using pertinent data offered by participants.

In-Depth Vibration Analysis
* Practical use of time waveform analysis
* Expanding the use of phase in specific problem analysis
* Obtaining phase when no rotating part is reachable for reference or trigger
* Most common distortions of phase information and how to correct for them

Improve Field and Shop Balancing
* Difficulties and confusion due to variations of static/couple unbalance (with case histories)
* Overhung rotors, hot rotors, multistage pumps
* Weight placement procedures
* True precision balancing, faster and easier
* “Rigid” and “flexible” rotor speed considerations
* Minimizing balancing errors
* Preventing ‘whip’ inflexible rotors
* Balancing large rotors

Pumps and Pump Related Problems
* Determining mode shapes of overhung pumps

* Effects of resonance that could confuse spectral analysis
* Effects of resonance that alter phase analysis
* Correcting complex and unusual resonance problems
* Techniques for proving resonance

Insights into Signal Processing
* Understanding Windowing and how it can help as well as distort
