Application of bacterial preparations for bioreclaiming of disturbed soil within the zone of railway transport

The possibility of reclaiming actions with application of the biopreparation fertilization traditionally used in agriculture of the Republic of Tatarstan is analysed. The investigations were carried out by a series of small plot multiple-factor annual field experiments. The results showed the possibility of using of this method in the field of reclaiming of oil-contaminated soil.

Problems of organization of bulk freight traffic

The basic problems of organization of bulk freight traffic in stages of making up and braking up of freight flow as well as during delivery to terminal points are considered. The technological aspects of organization of transport called to optimize the interaction parameters of the owners of infrastructures of railway and industrial transport, carriers and operators of rolling stock, freight generating realm are described.

Methods of investigation and the calculation of reliability characteristics of the production process at the car servicing in the freight station subsystems

The issues of study and the analysis of reliability characteristics of the production process in station subsystems are considered. The nature and laws of failure distribution in the freight station subsystems were investigated. Analysis of production processes on the freight stations showed that the existing formulae overestimated results of the evaluation of the car waiting time of the service beginning. Formulae allowing to do a more accurate time estimate of car servicing waiting in production subsystems of a freight station were developed.

Optimization of the calculated curve of freight train operation on the span

A quality evaluation method of the calculated curves of freight train operation on the span at the random time taken which can be used at layout into block sections and for the evaluation of economic losses at various ways of interval traffic control as a result of train deviations from optimal speed curve, as well as for solving other tasks was developed. The variable hourly costs for train operation on the given span are used as an optimality criterion.

Methods of analysis of the operational efficiency of dispatcher control systems

The methods of estimate of efficiency of dispatcher's control systems at the operation stage are offered. In contrast to the known methods based on the evaluation of reliability and isolated system safety, the proposed methods allow to take into account operational load distribution on the subdivision, the effect of the structure of dispatcher control system, processes of formation and transmission of signals, etc. The application of methods developed in the article will improve the objectivity of the evaluation of the operational efficiency of dispatcher control systems.

Analysis of the calculation of the bearing capacity of car wheel pair with application of a method of principal components

The usability of a method of principal components to the calculation analysis of stress-strain state of car wheel pair is shown. Statistical estimation allows to specify the reliability indices of wheel pair. Using mathematical models of a method of principal components it is possible to predict the bearing capacity press-fit connection of a wheel and an axle of car wheel pair.

About the movement stability of multiaxis truck of rolling stock

The derivation of linearized equations of multiaxis truck movement with the force of elastic deformation of wheels and rails in the contact zone, which are various for different wheels, is submitted. The expression for the critical speed of truck movement is determined with Hurwitz criterion, and from this expression it is possible to determine the analytic connection between the dimensions of defects of truck running gears and additional forces of inertia generated by these developing defects which can theoretically prove restrictions on the permissible dimensions of defects that lead to the appearance of additional forces of inertia.
