Beginning Vibration Analysis with Basic Fundamentals By: Jack Peters Beginning Vibration Introduction Understanding the basics and fundamentals of vibration analysis are very important in forming a solid background to analyze problems on rotating machinery. Switching between time and frequency is a common tool used for analysis. Because the frequency spectrum is derived from the data in the time domain‚ the relationship between time and frequency is very important. Units of acceleration‚ velocity

undesirable effects like vibrations or noise [1]. Both vibrations and noise have negative impact on human safety and health. These effects may cause: a) balance disorder (motion sickness)‚ b) neck and occiput area pain (connected with stressed back muscles preventing excessive movement of head caused by vibrations)‚ common among professional drivers‚ These factors cannot be underestimated‚ because the consequences have unquestionable impact on human health and safety.

Researchers are working on alternative energy sources like solar‚ thermal‚ acoustics‚ and vibration. These sources are clean and have theoretically infinite life compared to batteries. Considering implantable and embedded microsystems that should operate and survive on their initial energy supply‚ these ambient energy sources are attractive alternatives. Among these alternative sources‚ environmental vibration is particularly attractive because it is almost everywhere in our living environment and
