Full-scale study of stress-strain state of ballastless upper structure construction of rail way in terms of train dynamic load

摘要

This article is about the ballastless tipper structure track operation in Russia. The Rheda 2000 construction was laid at the experimental section of railway track. The problem of cracking was founded while using this construction. In order to determine the railway track stress-strain condition with terms of train dynamic load the experiments were carried out by using of strain gauges. The experts got the following results: the cracks appeared at the main plate in the locations of the fixed maximum tensile stress. Furthermore, the rolling-stock speed grows up with increasing of vertical and longitudinal voltage on the primary site of the linear dependence.
