It is known a priori that vibrations that occur in the elements of the track structure during the passage of a train load are a superposition of free and forced mechanical vibrations. It has been established that the range of oscillation frequencies of th... see more

In the article the issues of testing the parts of a fastening ???-5 on reliability are considered and the modem way of fixing the backing anchor in a form at a factory of ferro-concrete sleepers is presented.

IN THIS PAPER, EFFECT OF UNCERTAINTY OF FASTENING SYSTEM PROPERTIES ON THE WHEEL/RAIL DYNAMIC FORCE (WRDF) WAS INVESTIGATED. FOR THIS PURPOSE, TWO DETERMINISTIC AND EPISTEMIC MODELS OF VEHICLE/TRACK INTERACTION WERE DEVELOPED, USING THE FINITE ELEMENT MET... see more

The railroad structure consists of rail steel, sleepers, fastening, ballast, sub-ballast and subgrade. The load of the passing train at a certain speed can produce vibrations channeled through the train wheels to the railway steel to be forwarded to ... see more

Purpose. The possibilities of railway transport for organizing transportation between the countries of the European Union and Ukraine are not fully utilized, since there are a number of technical differences in transport systems, namely: wheel gauge, char... see more

The basic stages of introduction on railways of cross ties from ferroconcrete are resulted. The data on rates of laying and extent of a railway on the ferroconcrete basis on Russian and Byelorussian railways are resulted. It is shown, that the width of a ... see more

The problem of creation of resilient rail fastening is considered for high-speed train services. The article describes the research methods of loading and resiliently-deformed state of resilient terminals and presents the results of investigation of the i... see more

In the given publication it is proved that in calculations of maximum dangerous width of a rail track it is necessary to consider both plays and presence of tolerances at manufacturing the elements of rail fastenings.
