VIBRATION ASSESSMENT QUIZ •
SHOULD I ATTEND THE ENTRY LEVEL OR ANALYSIS I SEMINAR? “Should I attend the Entry Level Level or Analysis I seminar?”, “Am I ready for Analysis I?” are common questions for those beginning a new career in vibration analysis. Analysis I assumes and builds on the student having a basic understanding of vibration measurement and analysis. The following questions are taken from the Entry Level training manual and are designed to help one make the decision.
•
It is recommended that you start with the “Entry Level” seminar if you cannot fully answer 80% of the following questions with confidence: · What are, and, can I explain each of the 5 steps in most successful PdM programs? · Can I explain each of the 3 basic characteristics measured in vibration? · Can I explain the effect that decreasing dynamic force has on amplitude response? · Can I explain the period of vibration? · Can I explain the difference between a Natural Frequency and a Resonance? · Can I explain the difference between a Resonance and a Critical Speed? · What units are used to express amplitude and why use one over another? · Do I understand what Phase is and when to use it? · Can I find and explain each of the basic menu selections in my analyzer? · Can I explain Transducer Sensitivity and Frequency Range? · What is a low frequency accelerometer? accelerometer? When do I use it? How do I tell my instrument which accelerometer is connected? · Can I explain why and when to turn off Sensor Power?
· Do I know when to use Auto Range and why? · Does a Shear Mode Accelerometer have advantages over Compression Mode? If so, what are they? · Can I explain the common “Average Types”? · What are Routes? · Can I explain why Sidebands appear in a spectrum? · Can I explain how Sidebands help the analyst? · Can I explain how a Beat differs from classic Amplitude Modulation? · Am I familiar with common terms such as Sub-synchronous, Fundamental, Harmonic…? · Can I explain why most rolling element fault frequencies are Nonsynchronous? · Can I explain what indicates the severity of a gear problem? · Can I explain why high amplitude at 2X Line frequency indicates an eccentric rotor in an AC induction motor? · What is the difference between Route Mode and Analysis Mode? · Can I explain how Dynamic Range affects the reading?
