Method for measuring track corrugation by utilizing axle box vibration and impact information

The invention provides a method for measuring track corrugation by utilizing axle box vibration and impact information. A vibration and impact information acquisition device contains a rotating speed sensor S arranged on a wheel set shaft of an operating vehicle, a vibration and impact detection sensor A1 and a vibration and impact detection sensor A2 which are arranged on an axle box bearing block at the two ends of a wheel set, an online monitoring device JKQ and a corrugation ground analysis system DMXT, wherein the rotating speed sensor S, the vibration and impact detection sensor A1 and the vibration and impact detection sensor A2 are connected with the online monitoring device JKQ, and detection, acquisition, diagnosis, analysis and decision of vehicular corrugation information of the operating vehicle are realized by virtue of the online monitoring device JKQ or by downloading data of the online monitoring device JKQ to the corrugation ground analysis system DMXT. The method for measuring the track corrugation by utilizing the axle box vibration and impact information has the advantages that the axle box vibration and impact information of the operating vehicle are acquired, based on a generalized resonance measurement principle, vehicular real-time track corrugation wave length and wave depth measurement and analysis or track corrugation wave length and wave depth measurement and analysis after downloading is completed are realized, and the manual workload is greatly reduced.
