Separation of the Train Vibration Signal Based on Improved Fast ICA
Xingyuan Zhang, Jiliang Tu, Decun Dong · 2011
A separation method of the vibration signal based on improved fast ICA was proposed. It adopted the steepest descent method to improve the convergence rate. Improved fast ICA method is applied to separation of vibration signal from the train's running gear. Separation results proved that the method is feasible and effective. The method is contributive and instructional to train's running gear vibration fault-diagnose.
