Purpose:
The purpose of this course is to teach maintenance craftsmen basic vibration analysis so that they can effectively use their facilities vibration monitoring equipment to assess the condition of machinery. The intent is to enable them to properly identify the most common vibration signatures in the time and frequency domains. They will gain an understanding of what vibration analysis is, how it works and how they can use it to diagnose problems in machinery.
Objectives:
Objectives: At the completion of this course, the student who actively participates will:
- Understand the time and frequency domains
- Understand the sources of signals in the spectra
- Be able to calculate characteristic frequencies
- Understand the uses of different sensors
- Understand proper FFT setup.
- Be able to collect consistent, repeatable data
- Be able to use software analysis tools

Description:
This is not an introductory course. Prerequisites are the Vibration Monitoring Introduction course plus at least six months experience in an active vibration-monitoring program or equivalents. Without the requisite experience and knowledge, participants will not gain full value form the course.
The course starts with a review of basic vibration theory. Then common causes of vibration in machinery are introduced. Their unique signatures in the vibration spectra are described, followed by practice in identifying simple signals. Next, practice on simulated machinery signals is conducted. Once the students are comfortable with the process, actual measurements are taken on plant equipment if possible. Those signals are analyzed and uploaded to the vibration software. Heavy emphasis is placed on how to collect good data, including setup of the database and datalogger.
Content:
- Introduction
- What is vibration and where does it come from
- Common vibration causes in industrial machinery
- Proper equipment setup for analysis
- Identifying problems using vibration spectra and time waveforms
