Method for evaluation of vibration signal, involves forming vibration signal as total signal from interference of low frequency fluctuating base signal and high frequency vibration signal

摘要

The method involves forming a vibration signal as a total signal (s-ges) from the interference of low frequency fluctuating base signal and high frequency vibration signal. The total signal is scanned with high scanning frequency. An upper envelope (sh-max) and a lower envelope (sh-min) are deduced from the scanned value of the total signal.
