Vibration Analysis FFT, PSD, and Spectrogram Basics

Vibration is an oscillating motion about an equilibrium so most vibration analysis looks to determine the rate of that oscillation, or the frequency. The number of times a complete motion cycle occurs during a period of one second is the vibration's frequency and is measured in hertz (Hz). For simple sine waves the vibration frequency could be determined from looking at the waveform in the

Vibration Measurements Vibration Analysis Basics

Vibration analysis starts with a time-varying, real-world signal from a transducer or sensor. Analyzing vibration data in the time domain (amplitude plotted against time) is limited to a few parameters in quantifying the strength of a vibration profile amplitude, peak-to-peak value, and RMS, which are identified in this simple sine wave. The peak or amplitude is valuable for shock events, but
