A Qt-program to compute dynamic moduli of elasticity of timber boards, by analyzing an input signal and computing the corresponding eigenfrequencies. It was developed specifically to work with the VIB-E-220 data acquisition device (Polytec) together with a laser vibrometer, however, it is very general and can be used with other signal sources (any microphone basically).
- Live preview of the input signal
- Autotrigger FFT when an impulse is detected
- Chose from different input sources (microphones)
- Compute dynamic modulus of elasticity based on the obtained frequency, given the dimensions of the board and weight
- Works on Linux and Windows (and probably MaxOS, but I haven't tested that)
That's it! Pretty cool, right?
Use uv:
git clone https://github.com/cristobaltapia/vibrometer_analysis.git
cd vibrometer_analysis
uv sync
uv run vibrometer
