The FFT amplitude however shifts down as the bandwidth is increased. The PSD amplitude does not shift because it is normalized to the frequency bin width. This normalization that occurs in a PSD calculation makes it so much more desirable to be used when analyzing random vibration signals.

We will want to make sure this equipment can handle the vibration levels in this environment so we may require a test organization to quantify that environment. I used an enDAQ sensor recently on a commercial flight to do just this, but I wanted to understand what type of vibration levels us humans were exposed to by measuring the seat in front of me.

Check out the data below along with a PSD again this is all available to download. Nothing beats the real data! This Fourier transform outputs vibration amplitude as a function of frequency so that the analyzer can understand what is causing the vibration. The frequency resolution in an FFT is directly proportional to the signal length and sample rate. To improve the resolution the time of the recording must be extended; but be careful of a changing vibration environment. A spectrogram takes a series of FFTs and overlaps them to illustrate how the spectrum frequency domain changes with time.

If vibration analysis is being done on a changing environment, a spectrogram can be a powerful tool to illustrate exactly how that spectrum of the vibration changes. A power spectral density PSD takes the amplitude of the FFT, multiplies it by its complex conjugate and normalizes it to the frequency bin width. This allows for accurate comparison of random vibration signals that have different signal lengths.

For this reason, PSDs are typically used to describe random vibration environments like those specified in military and commercial test standards. Before you can get started with your vibration analysis, you'll need to gather some vibration data! If you haven't gotten that far, explore some vibration measurement options ; and if you're going the route of accelerometers, make sure you select the right accelerometer type. If you're at a loss for how to perform the vibration analysis, download and use the MATLAB script that created all the plots presented in this post as a reference.

If writing your own code sounds a bit too complicated, then going the route of a standalone vibration analysis software package may be the best bet.

Share This. The same is true for peak-to-peak with the added benefit of providing the maximum excursion of the wave, useful when looking at displacement information, specifically clearances. The RMS root mean square value is generally the most useful because it is directly related to the energy content of the vibration profile and thus the destructive capability of the vibration. RMS also takes into account the time history of the wave form. Real World FFT and Spectrogram Examples Vibration Analysis of a Car Engine In real world applications there will typically be many different frequency components of a vibration profile as well as mechanical and electrical noise.
