Abstract

Digital time interval technique for the measurement of torsional vibrations in rotating shafts was discussed. An in situ encoder calibration method was presented that creates a reference array representative of the actual encoder angular intervals. A resampling algorithm was applied to create an array sampled with a constant time interval basis to minimize the error. Results show that there was a reduction in frequency smearing effects from running speed variations even with precision optical encoders.
