Here is a signal analysis package GUI written using Tkinter: vibrationdata_gui_python.zip

It is compatible with Python versions 2.7 to 3.3, and hopefully future 3.x versions.

vibrationdata.py is the main script.

The remaining scripts are supporting functions.

These scripts demonstrate the use of multiple windows.

The following signal analysis functions are currently available:

Statistics

Trend Removal & Scaling

Butterworth Filter

Bessel Filter

Fourier Transform

Fast Fourier Transform (FFT)

Waterfall FFT

Power Spectral Density (PSD)

SDOF Response to Base Input

Shock Response Spectrum (SRS)

Rainflow Cycle Counting

Differentiate Time History

Integrate Time History

Autocorrelation

Cross-correlation

Cepstrum & Auto Cepstrum

Sound Pressure Level (SPL)

The following PSD functions are also available:

Overall GRMS

SDOF Response to Base Input PSD

Vibration Response Spectrum (VRS)

The following miscellaneous functions are also available:

Sine Amplitude Conversion

SDOF Response: Peak Sigma for Random Base Input

SDOF Response to Classical Pulse Base Input

More will be added in future revisions…

Python Tip from Brian Hawkins for numpy arrays.

a = b merely creates a new reference to b. a[:] = b means “set all elements of a equal to those of b”. The difference is important because numpy arrays are mutable types.
