Vibration Analysis for Service Centers coverThis 48-page manual was developed following EASA’s 12-part Vibration for Service Centers webinar series. It serves as an introductory training resource for service center technicians and supervisors involved in measuring, evaluating, and correcting vibration and balancing issues on machines under repair – as opposed to the in-plant predictive maintenance tasks covered in most general classes on the subject.

This document is intended as basic introductory training material for anyone who may be involved in evaluating or correcting vibration issues on machines repaired in the service center. Only certain sections may be of interest depending on the area and amount of involvement in vibration issues.

For a technician with responsibility for analyzing and correcting vibration and balancing issues, a general understanding of all of the information is essential. For technicians who will conduct field vibration and balancing services in customers' facilities, additional training is strongly recommended. A Level 1 vibration analysis class (usually 4 or 5 days) is a first step toward the competence needed for conducting field services. A Level 2 class is recommended. A number of providers offer ANSI-certified Level 1 and Level 2 vibration analysis classes, which normally include an opportunity for certification.

Major sections in the document include:

  • Introduction and Overview
  • Vibration Basics: Amplitude, Frequency and Phase
  • Vibration Tolerances
  • Basic Vibration Analysis
  • Dynamic Balancing Basics
  • Resonance
  • Rolling Element Bearing Vibration
  • Demodulation and High Frequency Band Measurements
  • Field Analysis Techniques
  • Field Balancing—Problems and Solutions
