Module 1: Overview of Vibration
  Lecture 1: Introduction to Vibration Control
 


Vibration signifies to and fro motion about some equilibrium configuration

This is undesirable in most engineering systems.

The ill effects of vibration include:

 

 Fatigue failure

  • Structures like aircraft fuselage
  • Machine components like crankshaft.

 

 Severe damages due to resonance

  • collapsing of bridges,
  • damages in transmission lines
  • damages to offshore structures.

 

Malfunctioning of sensitive Instruments/ systems

  • payloads from vibration of launching rockets.
  • high precision machining
  • micromachines & microassembly
   Loss of accuracy of work-piece due to vibration of machine tools.
