Evaluation of dynamic measurement uncertainty in the time domain in the application to high speed rotating machinery

Abstract

The results were tested when evaluating the dynamic uncertainty in measurements of the vibration acceleration of an engine. It was established that the maximum value of the dynamic uncertainty of the measurement of the vibration acceleration stands at 0.14 m/s2 for an observation time of 300 s and with a nominal value of the signal of vibration acceleration of 2.34 m/s2 at a frequency of 6 kHz, which in relative units is 6%.
