摘要

Aiming at the problem of the rail corrugation detection about low efficiency and low success rate, a method based on wavelet packet energy entropy (WP-EE) was proposed. First, the rail corrugation and the train physical fitting models were established, and then a coupling dynamics model was developed by using SIMAPCK. Next, four-layer wavelet packet decomposition of the axle box vibration signal is performed, wavelet pocket energy entropy and wavelet energy of each node are calculated. Finally, the simulation results were compared which reflect the information of rail corrugation.
