Development of arbitrary waveform torsional vibration signal generator

In order to more accurately evaluate or calibrate the electronic torsional vibration test analyzer and analysis method, a torsional vibration signal generator is developed in the present study. The developed device generates a tooth pulse interval sequence based on the inverse solution of the shaft torsional equation. Moreover, a single-frequency signal, inter-harmonic signal, time-varying harmonic signal, and noise-containing time-varying...
