Vibration Analysis: Machine Vibration, Basic Theory

About

Understanding machine vibration is vital to the effectiveness of a successful predictive maintenance program. This course discusses condition monitoring and its fundamental application to rotating equipment. It reviews the relationship between frequency and vibration, as well as defining commonly used vibration analysis terms.

This presentation introduces the theory of Machine Vibration. The course explains the principles of how forces cause machines to vibrate and includes a visual explanation of critical terms such as frequency, resonance and time/frequency domains, amplitude, displacement, velocity and acceleration.

Objectives of this course are to understand:

-The relationship between frequency and vibration
-Natural frequency and resonance
-Time and frequency domains
-Vibration amplitude, the relationship between displacement, velocity and acceleration
-Phase measurements and phase angles, and define commonly used vibration analysis terms
-Be able to identify a time wave
