Vibration Analysis,

Machine Fault Diagnosing

and Advanced Techniques

Level 2

Course Overview

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 analyzer 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 analyzer and machine so that you feel confident in the decisions you make.

Course Outlines

  • Review of maintenance practices.
  • Review of condition monitoring technologies.
  • Principles of vibration; Review of basics, waveform, spectrum (FFT), phase and orbits.
  • Understanding signals: modulation, beating, sum/difference.
  • Data acquisition.
  • Signal processing.
  • Vibration spectrum analysis.
  • An introduction to time waveform analysis.
  • An introduction to orbit analysis.
  • Phase analysis: bubble diagrams and ODS.
  • Enveloping (demodulation), shock pulse, spike energy, PeakVue™.
  • Equipment testing and diagnostics including impact testing (bump tests) and phase analysis.
  • Corrective action.
  • Running a successful condition monitoring program.
  • Acceptance testing.
  • Review of ISO standards.

Learning Competencies

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

  • How a well-designed program, and the reliability centered maintenance approach (with precision balancing, alignment, lubrication and resonance control), will improve the OEE and therefore the bottom line.
  • The condition monitoring technologies: infrared analysis (thermography), oil analysis, wear particle analysis, motor testing – via supplementary training.
  • How machines work – via supplementary self-study via the “Equipment Knowledge” section.
  • How to select the correct measurement location and axis, and collect good, repeatable measurements.
  • What the Fmax, resolution, averaging and other analyzer settings mean, and how to select the optimum settings for a wide variety of machine types.
  • How to analyze vibration spectra, time waveforms, envelope (demodulation), and phase measurements.
  • 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.
  • How to set alarm limits manually and with statistics.
  • How to balance and align a machine, and correct a resonance condition.

Who Should Enroll?

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.
