While examining results of vibration analysis of a rotating piece of machinery, you find very high amplitude/displacement readings at a very high frequency at one measuring point. What would that indicate?

🔍 Key Concepts

• Relationship between vibration frequency and rotating speed • Typical vibration signatures of imbalance, misalignment, looseness, and bearing defects • How measurement location affects what the sensor picks up

💭 Think About

• Compare the described vibration frequency to shaft running speed: which faults usually show up near running speed vs much higher frequencies? • Think about which fault is most localized to one measuring point rather than seen broadly across the machine. • Recall which condition often creates many small, rapid impacts that show up as very high-frequency vibration.

✅ Before You Answer

• Identify whether the symptom is very high frequency vs. 1× or 2× running speed. • Note that the problem is strongest at one measuring point, not everywhere. • Match the clue high amplitude at very high frequency with the fault type most associated with rolling contact elements.
