What is the primary reason for using time waveform analysis in vibration measurement?

Time waveform analysis is primarily utilized in vibration measurement to capture transient events. These transient events are short-duration signals that can indicate various mechanical issues, such as impacts, misalignments, or sudden changes in operating conditions. By examining the time waveform, you can observe these sudden changes and spikes in vibration that a frequency domain analysis might overlook, providing critical insights into the health and behavior of the machinery.

This capability is essential for identifying problems that develop quickly or are not part of steady-state operation. Analyzing the time domain allows for a more thorough understanding of the dynamics at play during these transient occurrences, enabling more effective troubleshooting and maintenance decisions.
