Wear Identification of Vibration Drilling Bit Based on Improved LMD and BP Neural Network
In view of the low accuracy of single signal monitoring for the wear state of vibration drilling bit, a multisignal acquisition system for the wear state of ultrasonic axial vibration drilling bit is built to collect the drilling force, vibration, and acoustic emission signals under three different...
