Vibration is a physical phenomenon. Throughout the ages the concept of vibration has fascinated brilliant minds. Geniuses like Copernicus, Kepler, Newton, Rayleigh and a host of others have put in their minds into this problem. They studied this phenomenon with whatever simple scientific and mathematical tools that were available to them at that time. As technology advanced, became diversified and sophisticated, the engineers were still faced with problems, for which either solutions did not exist or the existing solutions were inadequate. Problems related to vibration still continued to haunt them. The aim of this paper is to bring physical insight to the modeling, analysis and control of vibration through an improved understanding of the fundamental principles of vibration. Virtual instrumentation (VI) concept has been chosen for vibration analysis, as VI offers the flexibility for measurement of vibrations generated from diverse sources, and adapts to meet diverse requirements. Lab VIEW (ver 6.1) along with NI Data acquisition hardware was used for developing this virtual instrument.
