Fault diagnosis of shearer rocker bearing based on improved EEMD and HMM

The paper proposed a fault diagnosis method of shearer rocker bearing based on improved EEMD and HMM. The method uses improved extreme points symmetric extension and cosine window function to reduce impact of end effect on decomposition results, so as to improve signal decomposition precision; then...
