A Novel Approach for Acoustic Signal Processing of a Drum Shearer based on Improved Variational Mode Decomposition and Cluster Analysis
During operation, the acoustic signal of the drum shearer contains a wealth of information. The monitoring or diagnosis system based on acoustic signal has obvious advantages. However, the signal is challenging to extract and recognize. Therefore, this paper proposes an approach for acoustic signal...
