CAT II Vibration Analysis (VCAT-II)

CAT II Vibration Analysis

Do you already have an understanding of vibration fundamentals and want to become more confident and accurate in your diagnoses? Then you will enjoy this course!

As a Category II analyst you are expected to know how to test machines correctly, how to diagnose faults accurately (and perform additional tests to verify your diagnosis), how to set vibration alarm limits, and how to correct certain types of faults. Now it is time to understand what those analyser settings mean so that you can take the best measurements. Now it is time to understand why the vibration patterns change the way they do – and how to use time waveform analysis and phase analysis to verify the fault condition.

We are offering you the opportunity to not only learn these topics, but to truly understand the analyser and machine so that you feel confident in the decisions you make.

Aim

You will come away from the course with a solid understanding of:

1. How a well-designed program, and the reliability centred maintenance approach (with precision balancing, alignment, lubrication and resonance control), will improve the OEE and therefore the bottom line
2. The condition monitoring technologies: acoustic emission, infrared analysis (thermography), oil analysis, wear particle analysis, motor testing – via supplementary training
3. How machines work – via supplementary self-study via the “Equipment Knowledge” section
4. How to select the correct measurement location and axis, and collect good, repeatable measurements
5. What the Fmax, resolution, averaging and other analyser settings mean, and how to select the optimum settings for a wide variety of machine types
6. How to analyse vibration spectra, time waveforms, envelope (demodulation), and phase measurements
7. How to diagnose a wide range of fault conditions: unbalance, eccentricity, misalignment, bent shaft, cocked bearing, looseness, rolling element bearings faults, journal bearing faults, gearbox faults, resonance, and other conditions
8. How to set alarm limits manually and with statistics
9. How to balance and align a machine, and correct a resonance condition

Who should attend?

If you have been performing vibration analysis for more than twelve months, and feel that you have a good understanding of the fundamentals, then you are ready to step up to the Category II course. (Note that you require 18 months experience to be certified.) Anyone who wants to be confident and capable of diagnosing a wide range of fault conditions, correct certain conditions, and taking accurate measurements needs to take this course. Many plant sites require contractors to be certified, and many employers require employees to be certified. The RMS / Mobius Institute course and certification program follows the ISO 18436-2 standard and the ASNT Recommended Practice SNT-TC-1A.

What is unique about this course?

RMS / Mobius make it unique.  We use 3D animations, Flash simulations, and numerous software simulators that completely demystify vibration analysis.  While vibration training courses have traditionally been very theoretical, difficult to understand, (and boring), you will be captivated by the RMS Training methods, and you will enjoy our practical approach.  You will take away skills that you can immediately apply to your job, and you will truly understand what you are doing.  When senior vibration analysts attend our classes they often say “if only I could have learned this way when I got started” – well, now you can!

Addition benefits unique to RMS / Mobius Institute courses

Classroom activities

• Sitting and watching an instructor can be boring…  When the instructor is using modern slides, 3D animations, and incredible simulators, there is no way that you will be bored, however there is nothing like hands-on participation.

Hands-on participation accelerates learning and enjoyment (depends on venue)

• In the RMS / Mobius Institute courses you can use the simulators, and you can collect readings and study real vibration patterns.  There is no doubt that the simulators make it easier to understand the topics we cover – but when you can use them yourself, the learning is further accelerated.

Workbooks provide feedback – do you really understand?

• We also provide quiz questions that help you check if you really did understand the topics, and that you will be able to make the right decisions in the field (and in the exam).  Every morning we have a lively discussion as we go through the questions.

Take away more than just knowledge

• We don’t just deliver an excellent course.  We provide you with resources that you can use before, during and after the course.

Get started before the course even starts

• Before you even start the course you can visit our Learning Zone Web site to take the self-paced iLearnVibration lessons (and read through the manual).  These lessons will help prepare you for the course – you will learn so much more if you go into the course with this knowledge.

Excellent materials that you will treasure forever

• During the Vibration Analysis Cat II (Jan) you receive a vibration analysis chart, vibration analysis pocket guide, a vibration reference guide, (a very handy booklet); a mouse pad that is covered with classic spectra representing common fault conditions; access to quiz styled sample questions and answers, and our VA Category II manual.  This new manual is easy to read, is filled with illustrations, follows the course slides exactly, contains an excellent “Equipment Knowledge” appendix, and can be used as a reference in the future.

Don’t stop learning just because the course ends

• For six months after the Vibration Analysis Cat II (Jan) (or longer for a small fee), you can continue to access the iLearnVibration self-paced material on the Web site.  If you forget something that you were taught, or you just want a refresher, then just jump on to the site and go through the fully narrated lessons.

Distance learning benefits

If the high cost of travel and accommodation, and the time away from your family and work has stopped you from receiving the training that you need, then you should consider our distance learning courses.

At a time that is convenient to you, and at a pace that works best for you, you can take our lessons and learn in a very similar way to attendees of our classroom courses. Depending upon the course, you can either view fully narrated slides, or you can watch a video of the class in action.

Narrated slides

Utilizing the popular iLearnVibration and iLearnAlignment products, we offer distance learning courses where you can view the lessons at your own page, in your own time, and get assistance from an instructor when any questions arise. Of course, you can just buy the products and learn at your own pace without assistance, but you are sure to benefit from interaction with the instructor. In certain courses, you can also interact with other students.

Video lessons

These are not noisy, unprofessional videos taken from actual classrooms, each video was carefully created and edited so that you receive the full benefit. As you can see in this sample, you see the instructor talking and you see the slides (and simulators) being used in high resolution. All you need is a good Internet connection and a good monitor (1024×768 or better) and you will be ready to start learning. You can pause and rewind the video so that you can see and hear the instructor cover the topic again.

In addition to the lessons, hands-on videos are presented where a variety of vibration analyzers are used to perform a range of tests. The tests include demonstrations of averaging (linear, rms, and peak hold), bump tests, run up and coast down tests, simple ODS tests, bearing fault detection tests, phase analysis, live spectrum analysis, time waveform analysis, and more.

You can also perform activities defined by the instructor, and take quizzes that will be reviewed by the instructor.

This is a great way to learn. The convenience of learning from home, and the reduced costs associated with travel, meals and accommodation make this a very attractive option – especially while the world’s economy is still recovering.
