Understanding the Interactive Waterfall Plot
In vibration analysis, a waterfall plot is a three-dimensional graph that displays the frequencies of an asset over time. It consists of many two-dimensional FFT graphs stacked up against each other taken at different time stamps.
Vibration measurement and analysis is an important instrument for characterization, monitoring and diagnostics of machinery, structures and plants. Analysis of the vibration behaviour of machinery is one of the most important and effective techniques for moni-toring the "state of health" of a machine.
Waterfall plot - Wikipedia
A three-dimensional spectral waterfall plot is a plot in which multiple curves of data, typically spectra, are displayed simultaneously. Typically the curves are staggered both across the screen and vertically, with "nearer" curves masking the ones behind. The result is a series of "mountain" shapes that appear to be side by side.
Analysis of the problem by a vibration specialist is required. This guide is divided into two sections. The first section introduces concepts and methods used to detect and analyze machinery problems. The second section examples “typical” ways in which various machinery problems show themselves and how these problems are “typically” analyzed.
How Vibration Data is Gathered and Processed for Analysis Vibration Plot Types Both spectrum and waveform provide useful data. Machinery faults often occur at specific frequencies and are most easily identified in the spectrum. Trend plots show changes in a measurement over time. The Time Waveform shows random events, periodic events and imapcting
Waterfall Analysis: Frequency Resolution and Smearing
Apr 18, 2012 · Waterfall analysis is a tool that is often used to evaluate the acoustic and/or vibratory performance of rotating machinery. The process involves calculating spectra using fast Fourier transform (FFT) methods at incremental steps in rpm (revolutions per minute) as the rotational speed changes – either increasing (run up) or decreasing (coast ...
Waterfall Analysis: Frequency Spectrum or Order Spectrum?
Jul 25, 2012 · Figure 1: Spectrum waterfall from time (non-synchronously) sampled data. In order to illustrate what a typical spectrum would look like a single spectrum from this waterfall data at a simulated speed equivalent to 3000 rpm is shown below in Figure 2.
