振动分析 for Service Centers
This 48-page manual was developed following EASA’s 12-part Vibration for Service Centers 系列讲座. It serves as an introductory training resource for service center technicians and supervisors involved in measuring, 评估, 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 评估 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
- Basic 振动分析
- Dynamic Balancing Basics
- Rolling Element Bearing Vibration
- Demodulation and High Frequency Band Measurements
- Field Analysis Techniques
- Field Balancing—Problems and Solutions

Companion 12-part webinar recording series
This 12-part recording (15 hours) covers a wide range of topics on vibration.
Members rely on EASA to provide technical assistance and training in all areas related to machinery repair. In the area of machinery vibration, there are training providers that offer general classes in vibration analysis and balancing, but the content is geared to plant maintenance personnel who would be conducting in-plant predictive maintenance services. Some key areas important to EASA service center technicians is not covered adequately, and much of the content does not apply to vibration testing conducted in the service center. This course is designed to address those shortcomings and provide fundamental training in vibration analysis and balancing that directly applies to technicians working in the service center.
Main goals of the series
This 系列讲座 was designed to:
- Provide EASA service center technicians with the technical knowledge they need to effectively measure and diagnose vibration on machines being tested in the service center.
- Provide the foundation understanding necessary to use vibration data as an indicator of machinery condition
- Provide the fundamental knowledge of dynamic balancing necessary to use common balancing instruments in the service center
Who would benefit from watching this series?
Service center technicians who measure and analyze machinery vibration, and those who must evaluate the vibration data will benefit greatly from the fundamental understanding and knowledge provided by this training series. Service center engineers who may be involved in writing, interpreting and applying vibration and balancing specifications and tolerances will gain a practical understanding of the terms, definitions and parameters encountered in those specifications.
As with any technical subject, fundamental math skills will allow attendees to quickly comprehend concepts and apply techniques. Vibration results from the mechanical and electrical forces at work in machinery, and a fundamental understanding of those forces, and machine components that cause them, will aid in the understanding and application of the subject matter.
