A running state monitoring system of high speed railway EM U was introduced in this paper,which includes the testing devices on the track,data acquisition devices and evaluation analysis software. T his monitoring system can analyze running state and w heel defects of EM U by consecutive w heel-rail force acquired from testing devices on the track when high speed railway EM U passing through. T he technical scheme and key parts design and development were presented,which have been applied and verified in the gale special test of Lanzhou-Xinjiang No. 2 railway line,and provide important experiment data for EM U running state in windy conditions.
