Description
M&Bs 4-day Vibration Analyst - Level 3 seminar
provides the information and training essential for further advancing an analysts
Predictive Maintenance (PdM) skills, and preparing them to perform and/or
direct and/or establish vibration-based condition monitoring programs, and
perform in-depth diagnostics of machinery. Attendees are instructed in data
collection, analysis theory, identifying machinery faults, and performing
basic corrective actions. And the course follows
ISO 18436 guidelines for Vibration Analyst Level 3 for training and
certification (ISO 18436.2, Condition Monitoring and Diagnostics of Machines
- Requirements for Training and Certification of Personnel - Part 2:
Vibration Condition Monitoring and Diagnostics).
Our highly experienced field staff will
instruct your analysts in basic vibration measurement & analysis theory, and
teach them how to identify common machinery faults. Your analysts will be
able to properly measure vibration and diagnose most common machinery
problems at the end of the seminar. We also provide guidance on properly
configuring your PdM software for the correct frequency spans, lines of
resolution, and spectral band alarms, all specifically based upon the design
aspects of each machine.
This course does not focus on particular
hardware or software offerings. We teach concepts applicable to most
diagnostic systems and portable data collectors, and we highlight relevant
analysis limitations. And workshops at the end of each topic provide
relevant practice, and help prepare attendees for the optional Certification
Examination offered on the last day of training. |

Objectives
In addition to the skills required of a Level 2
Vibration Analyst, this course will help train analysts to:
-
Select the appropriate machinery vibration analysis
technique
- Specify appropriate vibration instrumentation hardware & software
for portable & permanently installed systems
- Measure & perform diagnosis of single-channel frequency spectra, as
well as time domain plots such as waveforms and orbits, under both
steady-state and unsteady operating conditions, with or without a phase
trigger
- Establish vibration monitoring programs, including determination of
machines for periodic & continuous monitoring, frequency of testing,
route plans
- Establish programs for specifying vibration levels & acceptance
criteria for new machinery
- Measure & analyze operating deflection shapes
- Understand & be able to direct the use of alternative condition
monitoring technologies (such as acoustic emission, thermography, motor
current and oil analysis)
- Recommend field corrective actions, such as balancing, alignment and
replacement of machine parts
- Use acceleration enveloping (demodulation)
- Perform basic single-plane field balancing
- Report to management regarding program objectives, budgets, cost
justification and personnel development
- Prepare reports for appropriate personnel on machine condition,
recommend corrective action and report on the effectiveness of repairs
- Provide instructions and technical direction to vibration trainees
