Abstract:
A method of measuring an axial force of a bolt may include fastening a joint using a fastener, receiving a vibration signal by a detector, transforming the received vibration signal into frequency domain data having a plurality of frames, analyzing the signal transformed into the frequency domain data, and predicting an axial force and indicating a predictive value thereof.
