Abstract

In vibration measurement, increasingly greater accumulative integration errors will be caused by the interference of DC components and low-frequency trend terms when an acceleration signal is integrated into velocity and displacement signals. To repress such errors, the principles and characteristics of time-domain and frequency-domain integration were analyzed, and the acceleration signal was preprocessed before integration. Afterward, the signal was subjected to low-frequency rejection processing so as to improve the integration accuracy. Moreover, the scope of application of the time-domain and frequency-domain integration method was analyzed and discussed. This method is of reference significance to the integration method of different acceleration signals.
