Mobius Institute Training Slides
The following examples are from the
slides used in the Mobius Institute classes. Of course, there
are a huge number of slides covering everything from the
fundamentals of vibration through to advanced diagnostic topics.
A large number of the slides include
animations and links to the simulations.
|
|
We cover maintenance practices
(including predictive maintenance and reliability engineering) so
that people can understand the benefits of the condition monitoring
program, and how it fits into the bigger picture. |
 |
|
We begin with a very simple animation of
a fan to explain the vibration waveform and spectrum, and terms such
as frequency, period, amplitude, rms, peak-peak, etc. |
 |
|
We have developed a range of artwork and
interactive simulators to help explain the FFT process and the
spectrum. |
 |
|
We also cover the orbit in both a
general sense and as a diagnostic tool. |
 |
|
We explain amplitude (and frequency)
modulation from a theoretical (simple) point of view and demonstrate
how it appears in the spectrum and waveform. |
 |
|
Beating is covered, as a many other
signal phenomenon. |
 |
|
We use lots of case studies, and when we
do, we can show the real "live" data, and play the signal through
the computer speakers. Being able to hear the vibration makes
it easier to understand the waveform and the condition. |
 |
|
Lots of real data... |
 |
|
Lots of case studies. |
 |
|
We try hard to make it clear why faults
occur, how the vibration pattern will look, and how to diagnose the
fault. |
 |
|
And we do this with lots of fault
conditions (depending upon the course you take). |
 |
|
Again, we use lots of case studies.
We use real data, and show how it changes as the fault develops. |
 |
|
In this case the bearing failed... |
 |
|
Of course, we cover demodulation
(enveloping) and all other vibration analysis techniques. |
 |
|
We utilize excellent 3D graphics. |
 |
|
In this slide the rotor is spinning, and
you can see the rocking motion - that makes it much easier to
understand the topic. And we have a large number of excellent
animations. |
 |
|
More 3D graphics and animations. |
 |
|
More excellent graphics. |
 |
|
We cover balancing in the corrective
action section. |
 |
|
Our simulations and animations will make
the concepts and procedures easy to understand. |
 |
|
Each step is animated on the screen. |
 |
|
We cover shaft alignment as well.
(We also offer a separate alignment course.) |
 |
|
We have 3D animations that clarify all
of the important concepts, and demonstrate procedures such as soft
foot measurements, dial indicator measurements, laser alignment, and
much more. |
 |
|
This animation shows how the stem may
lose contact during the rotation of the shaft. |
 |
|
We also utilize real photos and movies. |
 |
|
More 3D animations. |
 |
|
Our resonance simulator, and the
animations, make it easy to understand modes, natural frequencies,
resonances, and their correction. |
 |
|
We can explain all of the measurements
normally associated with bump tests, run-up/coast-down tests,
negative and peak-hold averaging, order tracking and transient
analysis. |
 |
|
And we use some great case studies.
Data from an Emerson Process
Management case study. |
 |
|
This pump animates on the screen. |
 |
|
Here is the same pump in a modal test. |
 |
|
And in a finite element analysis test. |
 |
|
We discuss the changes that can be made
to correct resonance conditions too. |
 |
|
|
This is just a sample from
the huge number of professionally developed slides. We have
strived to make them clear and simple; making it easier for you to
stay focused and keep up with the class - and excel in the exam.
