What is the function of a time waveform in vibration analysis?

In vibration analysis, the time waveform is crucial because it provides a detailed representation of how vibration signals change over time. This capability allows analysts to observe and identify transient events, such as impacts, shocks, or sudden changes in machinery operation, which may indicate issues like misalignments, imbalances, or mechanical failures. By examining the time waveform, one can assess the amplitude and frequency content of these vibrations in relation to time, offering insights into the behavior of the machine during those transient conditions.

Quantitative assessments of machinery performance, average speed calculations, and material hardness evaluations are more suited to other analytical methods and metrics rather than the specific interpretations possible through the time waveform analysis. Thus, focusing on the time domain signals is essential for diagnosing and troubleshooting mechanical problems effectively.
