Sample CVA - Certified Vibration Analyst Practice Questions
Try these questions from our free CVA - Certified Vibration Analyst practice tests. The correct answer and an explanation follow each question.
What is the crest factor of a vibration signal?
- A. The ratio of peak amplitude to RMS amplitude
- B. The ratio of RMS amplitude to average amplitude
- C. The ratio of peak-to-peak amplitude to RMS amplitude
- D. The ratio of velocity RMS to acceleration peak
Answer: A. The ratio of peak amplitude to RMS amplitude
Crest factor is the ratio of peak to RMS amplitude; for a pure sine wave it equals √2 (≈1.414), while impulsive bearing faults increase the peak without proportionally increasing RMS, raising the crest factor.
What is the polar (Nyquist) plot in rotor vibration analysis?
- A. A plot of spectral amplitude in polar frequency coordinates
- B. A plot of the 1× vibration vector (amplitude and phase) traced as shaft speed changes, shown on a polar coordinate graph
- C. A map of bearing clearances measured at multiple angular positions
- D. A frequency response function plotted in magnitude and phase format
Answer: B. A plot of the 1× vibration vector (amplitude and phase) traced as shaft speed changes, shown on a polar coordinate graph
A polar plot traces the tip of the 1× vibration vector on polar coordinates as shaft speed varies, creating a loop whose shape reveals critical speeds, modal behavior, and the quality of the balance correction.
What tool is primarily used to measure vibration?
- A. Thermometer.
- B. Accelerometer
- C. Barometer.
- D. Speedometer.
Answer: B. Accelerometer
An accelerometer is the primary sensor used in vibration analysis to measure acceleration, which is directly related to the forces causing vibration. It converts mechanical vibrations into an electrical signal that can then be analyzed to diagnose machine health. Accelerometers are widely favored for their accuracy and broad frequency response in detecting various machine faults.
What often causes excessive machine vibration?
- A. Software glitches.
- B. Misalignment, imbalance, or bearing wear
- C. Poor lighting.
- D. Wrong paint color.
Answer: B. Misalignment, imbalance, or bearing wear
Excessive machine vibration is typically caused by mechanical issues that disrupt the smooth and balanced operation of rotating components. The most common culprits include misalignment between coupled shafts, imbalance in rotating parts like impellers or rotors, or wear and damage to bearings. These issues introduce unwanted forces and motion, leading to increased vibration.
