EARLY DETECTION OF GEAR TOOTH CRACKING FAULT BASED ON RESONANCE BAND AMPLITUDE-PHASE DEMODULATION TECHNIQUE by SUN ShouBao, GUO Yu, WU Xing

“…Several traditional gear diagnosis methods are reviewed. The narrow band demodulation method is often accompanied with low-frequency interference and the resonance demodulation technique is limited in amplitude demodulation.According to the pros and cons of the traditional methods,the resonance band amplitude-phase demodulation technique was proposed for local gear fault detection to compensate the current gear diagnosis methods. …”

TOOL WEAR STATE MONITORING BASED ON WAVELET PACKET BP＿ADABOOST ALGORITHM by ZHU Xiang, XIE Feng

“…Aiming at the problems of less tool wear state data,low diagnostic efficiency,high maintenance cost and lack of effective diagnostic methods during CNC machine tool processing,A method of extracting features by wavelet packet analysis and kernel principal component analysis,and using BPAda Boost algorithm to diagnose tool wear state is proposed.The tool vibration signal and the cutting force signal are collected by installing an acceleration sensor on the machined workpiece of the numerical control machine tool and a force gauge on the workbench; Then the wavelet packet decomposition is performed on the signal to pass the signal through the low-pass filter and the high-pass filter of different dimensions,so that the conditional selection can be performed to form the energy value corresponding to the different frequency bands. …”
