Interactive Visualizers
New to the Red Wolf Reliability Training Center!
We’re excited to roll out a new collection of visualization tools designed to help you grasp challenging concepts in an intuitive way. Current releases include:
- Waveform Visualizer
- Bearing Defect Visualizer
- Beating Visualization tool
- Amplitude Modulation Visualizer
These visualizers will improve the understanding of rotating machinery concepts. Many vibration phenomena are difficult to explain using static plots or equations alone. Interactive tools allow users to dynamically change parameters and gain an intuitive understanding of what each parameter does. The main goal is to create an intuitive connection between theoretical vibration concepts and real-world machinery diagnostics.
These visualizers are intended for:
- Training new vibration analysts
- Demonstrating diagnostic principles to management or mechanics
- Supporting internal education
Education and skill development are our main focus, and these visualizers only elevate our users’ experience. Our vision is to create a growing library of resources that provides increasing value over time – a place where users can continuously learn, explore concepts, and build stronger technical understanding.

Our Interactive Visualizers
Waveform and Spectrum Visualizer
This visualizer demonstrates the relationship between a vibration time waveform and its frequency spectrum. The tool allows users to generate vibration signals composed of multiple sinusoidal components and observe how those components appear in both the time domain and frequency domain.
Users can adjust the frequencies and amplitudes of the individual signal components and instantly observe how the combined waveform changes. The Fast Fourier Transform (FFT) of the signal is calculated and displayed to show how each frequency component appears in the spectrum.
The visualizer also allows users to modify parameters such as spectral resolution and frequency limits, illustrating how these settings influence FFT interpretation.
Because many analysts learn FFT interpretation only from static spectra, this visualizer provides an intuitive way to understand how vibration signals are constructed and how those signals translate into spectral peaks.
Amplitude Modulation Visualizer
This visualizer demonstrates how amplitude modulation occurs in vibration signals and how it manifests in both the time waveform and frequency spectrum.
Users can adjust the carrier frequency, modulation frequency, and modulation index to observe how sidebands form around the carrier frequency. The tool simultaneously displays the carrier signal, the modulating signal, the resulting modulated waveform, and the FFT spectrum showing the carrier and its sidebands.
This visualizer helps explain common machinery faults where modulation occurs, such as looseness, gear wear, or mechanical impacts that modulate a dominant running frequency.

Beating Visualizer
The beating visualizer illustrates what happens when two similar frequencies interact. When two signals with slightly different frequencies combine, they produce a waveform whose amplitude fluctuates at the difference between the two frequencies.
Users can adjust the two frequencies and observe the resulting time waveform, which shows the characteristic “beating” envelope. The beat frequency and beat period are also displayed to demonstrate the relationship between the two source frequencies.
This concept is important in vibration analysis because beating can appear when multiple rotating components have similar speeds or when spectral peaks are closely spaced.
Rolling Element Bearing Visualizer
This tool demonstrates the characteristic frequencies associated with rolling element bearing defects. Using bearing geometry inputs such as number of rolling elements, pitch diameter, ball diameter, and contact angle, the visualizer calculates the fundamental defect frequencies including:
- Fundamental Train Frequency (FTF)
- Ball Pass Frequency Outer Race (BPFO)
- Ball Pass Frequency Inner Race (BPFI)
- Ball Spin Frequency (BSF)
The program plots these frequencies on a simulated vibration spectrum and allows users to select different defect types to see their expected spectral signatures. The tool also includes descriptions and images explaining the physical mechanisms behind each defect type.
This visualizer helps analysts understand how bearing geometry translates into measurable vibration frequencies.
