Abstract

This article deals with replacement of the magnetic grippers on the VPO-3-3000 machines with roller grippers. The novelty lies in establishment of dependences characterizing stress and strain in elements of the lifting and straightening devices and in rails during the operation. Reliability of the program for calculating the structural parameters of the lifting and straightening device for the VPO-3-3000 track renewal machine is shown. The developed design of the lifting and straightening device makes it possible to select the rational parameters of technology and the operating mode of the device. This design is recommended for use when developing working bodies for the straightening machines. The article presents calculation of the lifting and straightening device structural elements' strength during operation, in the Ansys WB software package.

Summary

Introduction

Railway ballast is the railway track foundation that is composed of graded stone ballast. One of the main areas of resourcesaving technologies used in repairing the railway track is the deep cleaning of the gravel ballast layer [4]. The quality of leveling is determined by requirements for the accuracy of positioning a railway track in terms of level, longitudinal section and plan. Information about the degree of the ballast consolidation under sleepers is important because it gives the possibility to evaluate the quality of the repair works, as well as further deformation of the track geometry. As studies show [11,12,13,14], a well-consolidated ballast layer after the track repair enables to extend the lifecycle period of the ballasted track and track structures significantly. The ballast layer loses its bearing capacity
