The results were approbated when evaluating the engines vibration acceleration dynamic measurements uncertainty. It was established that maximum value of vibration acceleration dynamic measurement uncertainty amounts to 0.137 m/s² for observation time of 600 sec and vibration acceleration signal nominal value of 0.35 m/s² at a frequency of 6 kHz. |
