Virtual Class

Dear Clients, Friends, & Associates:
As a result of the highly favorable reviews we received for its first dozen offerings in 2012 through 2020, I
am pleased to announce that we will be repeating our week-long rotordynamics training course this coming
March. The course, entitled “Practical Rotordynamics for Real Machinery” will be presented the week of 22
March, 2021.
Because of the COVID travel restrictions, we will be presenting this course virtually for the first time. We
had a “trial run” at the Turbomachinery Symposium in December, presenting some of the same info. that is
in this course, and the reviews were excellent. Still, since we have not done this virtually before, we are
offering a substantial discount on the cost of the course.
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 wellknown
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 last year’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

  • In addition to the sessions, if there is interest, we will be happy to host a short Q&A session on Friday the 29th. Additionally, we will ensure that there will be plenty of time for informal interaction with all three instructors, including breaks and lunches.
