What is the PSD in Vibration?

Random

Author Jared Van Baren

In vibration analysis, PSD stands for the power spectral density of a signal. Each word represents an essential component of the PSD. The power spectral density (PSD) is the most common tool for analyzing random vibration. Resonances and harmonics hidden in a time-history graph are visible in a PSD graph. In practice, generating a PSD is usually the first step in examining and analyzing a random waveform.
