Vibration Studies & Its Measurement & Control

Mechanical vibration refers to the oscillating motion of an object about a reference position. It is a result of dynamic forces in machines which have moving parts. Vibration disturbances occurred in machines and intricate electronic equipment, if left unattended, will increase product’s’ downtime, increase manufacturer’s maintenance and warranty costs and reduce user satisfaction. It is an important task for product designers as well as equipment manufacturers to understand and control the unwanted vibration occurs in these machines.


This two-day technical course provides participants a better understanding of vibration phenomenon, vibration isolation theory and practical considerations, vibration measurement and signal processing. It aims to assist practicing engineers in resolving their maintenance or design issues arising from the vibration of machines.

At the end of the course, participants will have a better understanding on:

  • mechanical vibration and its underlying theory
  • vibration isolation methodology and its practical considerations
  • how to set up a vibration measurement system, and
  • the essentials of digital signal processing or frequency domain analysis.
