Wheel Polygonalization Identification Method Based on Fluctuation of Temperature Data and Wheel Set Dynamic Monitoring Data

Abstract

With the increase of running time and speed, the wheel polygon phenomenon of high speed EMU is increasing gradually. Based on the analysis of the influence of wheel polygon on vehicle running state and the observation and statistics of the wheel set dynamic monitoring data and the wireless transmit device system data, a method of the wheel polygonalization identification is proposed which integrates the fluctuation of axle temperature data and wheel set dynamic monitoring data to improve the safety of high speed trains, so that the health status of high speed trains can be better monitored.
