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

Resonance
* 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
* The use, advantages and drawbacks to filters
* DFT vs FFT
* Pro’s, Con’s and relationships of time, frequency and phase
* Vectors and how they can distort
* Demodulation/high frequency analysis

Miscellaneous Topics
* Preparing vibration reports that managers can use
* Why amplitudes may increase after proper machine corrections
* Drive belt related vibrations
* Further tips for gear problem analysis
* Reciprocating machinery analysis
* A practical look at oil whirl
* Common errors and misconceptions in vibration troubleshooting
* Developing a more complete and productive vibration control program.  Learn the effective relationships and roles of those in a world class vibration control program.
* What goes wrong in the first place!
