Fault Diagnosis of Train Bogie Bearing Based on Multi-scale Sample Entropy Improved Extreme Learning Machine
Train bogie bearing is affected by track excitation, uncertainty of running speed, impact vibration of track joints and vibration of other components. The vibration signal is nonlinear and non-stationary, which makes it difficult to extract fault characteristics and fault diagnosis accuracy is low....
