Introduction to Vibration Study and Its Effects

Mechanical or structure vibration occurs everywhere, be it in our homes, at work or during transportation. Vibration is often a destructive and annoying side effect of a useful process or intended operation. It causes wear and fatigue and is often responsible for the ultimate breakdown of the machine.


This introductory course on vibration study provides participants a better understanding of vibration phenomenon; the sources of vibration and their detrimental effects; and the general vibration reduction measures. It aims to raise awareness of the participants on early treatment of the impending vibration issues.

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

  • Mechanical vibration phenomenon
  • Various sources of vibration and their effects
  • The different types of vibration control techniques
