What They Don't Teach BUT SHOULD! >>

What they don’t teach BUT SHOULD! 

  • Just about any Analyst can manage a World Class Vibration Program.  Getting it there and keeping it World Class … well that’s a different story!
  • A kind note to managers and engineers: Just because your might know everything about a brick (it’s density, porosity, physical, chemical & mineral properties, color, hardness, weight, cost, etc.) does not make one a professional brick mason. The same applies for vibration analysis .

  • Why do “Armchair Quarterbacks” always know enough to be an ‘expert’ … but never enough to solve the problem???

  • Vibration Analysis is as much of an art as it is a science, and some scientists failed art class!

  • When someone “pushes back” on making repairs to a 3600-rpm machine with high vibration levels, just mention that the machine is getting 5.2 million cycles closer to failure every day.

  • Expect the unexpected. A machine can fail within minutes after collecting ‘good’ data.  For example, like when a piece of foreign material suddenly breaks off and blocks the oil flow to a bearing.  Another example is a bearing cage failure; both are sudden and result in catastrophic failures with little or no warning.

  • There are no guarantees in this business. If it looks, smells and tastes like “unbalance”, its only “unbalance” if “balancing” fixes the problem.

  • There is no specific amplitude when a machine goes from “good” to “bad”, or when it will fail.  Use caution when referring to industry vibration charts … often referred to as “idiot” charts (because they are only good when no other information is available).

  • When exactly when does a rolling element bearing fail?
    1. When the bearing has a visible defect?
    2. When the bearing fault frequencies exceed 0.325 IPS-Pk?
    3. When someone directs that the component due to concerns about elevated noise levels?
    4. When the machine fails and stops supporting plant operations?

  • Identical machines will respond differently. Many machines are sensitive to changes in operating conditions.  Knowing your machine’s history and it’s sensitivities to changes in operating conditions is half the battle.

  • Know your strengths – fortify your weaknesses. There are four (4) key areas of  knowledge and experience. They are:
    1. Formal training (and 1 good week of formal training is worth about five years of full time experience … without the hard knocks and machine failures).
    2. Knowledge of the vibration test equipment and software.
    3. Proper data collection techniques and analysis experience.
    4. Knowledge of machine design and performance characteristics.

  • Vibration analysis cannot predict the run time to failure (RTF). RTF depends on too many conditions, such as operating speed, load, temperatures, component design, amount of unbalance & misalignment, quality & quantity of lubricant, and much more. Whenever someone asks you to predict RTF, just say you need to run that machine under the current (identical) conditions at least three (3) times to failure, in order to accurately predict RTF using “Statistics”.  Then ask that person for permission to start the science project. (Problem resolved!)

  • The quality of your data analysis is only as good as the data that’s been collected … and there is no “perfect” data. All spectral data is a compromise between the analysis parameter settings, meter settings, window types, measures of amplitude, frequency range, type of averaging, # of averages, % overlap, lines of resolution, measurement point locations, transients, background noise and more.

  • The more you know about vibration analysis, the more you’ll realize you don’t know.
    – A new Category-I Analyst with no prior experience basically knows enough to be dangerous to himself and plant equipment.
    – A Category-II Analyst with 1 full year of experience is right about 70% of the time. That means he’ll be wrong ~ 1/3 the time.
    – A Category-III Analyst with 5 year’s experience is right about 85% of the time.
    – A Category-IV Analyst with 10 year’s experience is right about 95% of the time.
    – VAI’s patented data analysis process approaches 100% accuracy and at 1/3 the cost of an in-house program.
    – Anyone guaranteeing they can correctly analyze any vibration problem is lying … or you won’t be able to afford their salary.

  • Experts will not always agree. Ask three (3) experts and you may get three (3) different answers.

  • The following usually means you have a new component vibration issue to address:
    1. Step changes
    2. New frequencies
    3. Increasing trends
    4. The appearance of your Maintenance Manager

Students always provide positive comments similar to the following: 


  • After completing my machinery vibration training course, I was able to apply new skills and knowledge to both identify, test and correct a complex machinery vibration issue at the plant involving “foot-related resonance” on a critical motor. The knowledge I gained not only provided a direct path to finding the cause of the vibration, but also gave me the confidence to perform the correction in the field, which is not easy when loosening mounting fasteners on a nuclear plant motor. It was also especially rewarding to be able to reverse the correction, and repeat the entire process in front of management.  At least I was the “cat’s meow” at the plant for the day.


  • The knowledge I gained not only provided a direct path to finding the cause of the vibration, but also gave me the confidence to perform the correction in the field, which is not easy when loosening mounting fasteners on a nuclear plant motor. It was also especially rewarding to be able to repeat the correction … in front of management.


  • The vibration training course I attended gave me the knowledge to detect and identify degrading machinery faults at the earliest possible time. I’m able to recommend focused corrective maintenance based on the type of machine (motor vs fan) and provide accurate reports of a degraded component’s health and its subsequent reliability to the plant. Based on the vibration analysis training I learned, our organization is now able to significantly reduce unplanned downtime and save a great deal of money by eliminating unnecessary maintenance activities. For example, performing a running soft-foot adjustment rather than replacing a motor (due to an air-gap issue).


  • Based on the vibration analysis training I attended, I’m now able to significantly reduce unplanned downtime and save a great deal of money by eliminating unnecessary maintenance activities. For example, I now know why some motors have a high amplitude 120 Hz vibration and how to fix it (perform a running soft-foot adjustment) rather than recommended a motor replacement.


  • I can now confidently determine the health and reliability of our machines using machinery vibration analysis. By performing routine vibration testing and analysis on a monthly basis, I can quickly and easily detect and identify developing issues while they are still minor. I can also direct Maintenance on what they should look for when issues need to be corrected. By reducing machinery vibration levels, the ‘wear and tear’ on our machines is greatly reduced resulting in increased equipment reliability, longer operating life … and a much happier management.


  • The machine vibration training course I attended not only increased my technical knowledge, but I also gained an ISO Certification from a very well-known agency. This “Certification” also documents my training and I can now clearly present my case when faced with some of the “know-it-all’s”. My certification also looks good on my resume and I plan on attending more advanced vibration training, even if I have to pay for it myself.


  • After obtaining my advanced vibration analysis certification, my managers tasked me to present an ISO Category II vibration certification training course to a number of other plant vibration analysts. The training went flawless and all but one (1) person passed their exam. Everyone was very impressed with the training and my supervisor acknowledged the value that I provided to the company. I also saved my company a lot of money by providing the training myself vs. hiring an outside training organization.
