An Introduction to Vibration Analysis (Part 1) Vibration analysis starts with defining a series of potential faults. The series of faults are then logically sorted in a way that the analyst can eliminate unlikely faults from the pool. We eliminate faults with Confirming Evidence and/or Refuting Evidence. The Vibration Fault Periodic Table™ “Structure” and “Method” is defined in our first topic.
An Introduction to Vibration Analysis (Part 2) The Basics of Vibration Analysis includes: Amplitude (How Much), Frequency (How Often), and Phase (a measure of Relative Motion). Part 2 will focus on Amplitude. Amplitude is a Severity parameter that can be defined as Displacement, Velocity, or Acceleration.
An Introduction to Vibration Analysis (Part 3) The Basics of Vibration Analysis includes: Amplitude (How Much), Frequency (How Often), and Phase (a measure of Relative Motion). Part 3 will focus on converting the raw transducer Time Waveform into a Frequency Spectrum. Defining the Frequency Spectrum opens a whole new fault detection and analysis capability in on-line trending and monitoring.
Dan Ambre, PE, is the founder and principal engineer at Full Spectrum Diagnostics. The FSD Machinery Analysis Division specializes in Experimental Modal Analysis (EMA) and Operating Deflection Shape (ODS) machinery diagnostics. Their Vibration Training and Certification Division makes use of these unique analyses by incorporating them into our course materials for a “real-life” training experience.
