Abstract
Are presented the results of experimental studies to evaluate the dynamic impact of rolling stock wheels with defects in the track structure. Was accomplished of evaluation the impact of movement speeds in the range of 10 to 40 km/h and loading of rolling stock on the edge stresses in the rails, and acceleration of the rail, were compared results of statistical processing of the measured data to determine the maximum permissible level of acceleration of the rails. Was analyzed the influence of defects of various sizes on the value of stresses in the rails and accelerations of rails. It revealed a monotonic increase of the maximum probability values of rail acceleration when passing a locomotive and wagon, regardless of how load the wagon, unlike the stresses in the edges of the rails, which do not depend on the speed in the test speed range. It was found that only in the value of the maximum possible value of the rail edge stresses for the empty wagon can not be detected the defects of wheel with using only the statistical methods, in the same time is presented the anomaly in the values of acceleration of the rail in the records of the empty wagon.
