The baseline course runs Monday - Thursday and is $2950.  

This course is being offered in person this year.

Dear Clients, Friends, & Associates:
As a result of the highly favorable reviews we received for its first dozen offerings in 2012 through 2023, I
am pleased to announce that we will be repeating our week-long rotordynamics training course this coming
The course, entitled “Practical Rotordynamics for Real Machinery” will be presented the

week of 22 April, 2024. The course will be presented in person is beautiful Sarasota, FL.

Since the course focuses on three major topics, we have three expert instructors participating, as follows:
1. Lateral Rotordynamics – Malcolm Leader, P.E. (President - Applied Machinery Dynamics) –
Malcolm has long been known as one of the best rotordynamicists in the world and is also well-known
for his keen troubleshooting abilities. He has written several dozen papers on these topics.
2. Bearings – Dr. Erik Swanson, P.E. (President - Xdot Engineering and Analysis) – In addition to
traditional fluid-film bearings, Erik is well-known for his expertise in foil and magnetic bearings.
Additionally, Erik is a wizard at using the DYROBES rotor/bearing computer code, which all of the
presented case studies have been done in.
3. Torsional Vibration – Mark A. Corbo, P.E. (President - No Bull Engineering) – In addition to having
authored some of the most well-known and best-received papers on the subject, I am currently
serving as the Chair for the Torsional section of the API 684 rotordynamics tutorial.

  • Although the syllabus from this spring's course is probably going to be “tweaked” a bit, some of the topics that will be addressed in depth include the following:
    1. Fundamentals/Basics
    2. Relevance of the various topics (i.e., why do we even care about this?)
    3. Modeling tips
    4. Undamped critical speed maps
    5. Unbalance response analysis
    6. Rotordynamic instability
    7. High pressure compressor stability analysis
    8. Pump rotordynamic considerations
    9. Fluid-film bearing types
    10. Tilting-pad bearings
    11. Specialized bearings (i.e. magnetic bearings, foil bearings, etc.)

    12. Seals
    13. Undamped torsional analysis
    14. Torsional Campbell diagrams
    15. Variable frequency drives
    16. Torsional response anlaysis
    17. Synchronous motor start-up analysis
    18. Reciprocating machine torsionals
    19. Machinery specific considerations
    20. API specifications and compliance
    21. Case studies

  • The course, which will cover all of the above topics, will run from Monday through Thursday (22 through 25 April)  and cost $2950  per participant. 

 Some of the benefits you would receive from taking this course include the following:

1. A great familiarity with lateral and torsional rotordynamics which would allow you to communicate more effectively with experts in the field.

2. A better understanding of the meaning and validity of rotordynamic results obtained from consultants and/or in-house rotordynamic codes.

3. A better understanding of the rotordynamic causes of common rotating equipment problems which would assist you when trying to troubleshoot field and test-stand problems.

4. A better feel for which system elements play an important role in rotordynamic behavior and which ones have little impact.  This would be valuable when evaluating potential design changes.

5. An appreciation that rotordynamic analysis can be performed in a practical and timely manner and does not require a "research project."

6. An appreciation for the large role that rotordynamic behavior plays in the reliability of rotating equipment and for the importance of evaluating that behavior in the design stage.
