Understanding Vibration Analysis Fundamentals
Before examinang specific studies, it 's essential too understand thee fundamentamental principles that make vibration analysis such an effective diagnostive tool. Any piece of equipment that rotates operates at a specific vibration frequency, and as thee equipment begins to unbalance, this vibration frequency changes, albeit in small ways, until is completely unbalances.
