In which frequency range is velocity testing applicable?

• A. Low frequencies
• B. High frequencies
• C. Mid frequencies
• D. Very low frequencies

Answer: (C)

Velocity testing is applicable in the mid-frequency range because this range effectively captures the dynamic response of a structure or machine while minimizing the effects of both very low and very high frequencies. In the mid-frequency range, the vibrations of equipment can be accurately represented, allowing for the assessment of various operating conditions. This range is critical for characterizing the behavior of machinery, as vibrations in this spectrum can reveal issues such as misalignments, wear, and other mechanical faults. Therefore, focusing on the mid-frequency range offers the best insight into the performance and potential problems within mechanical systems. Other frequency ranges may not provide the same level of detail necessary for effective diagnostics, making mid-frequency testing a preferred choice in vibration analysis.
