An increase in the speeds of the electric rolling stock has an impact on the energy indicators of the operation of the traction power supply system. One of the technical solutions to the task of equalizing the traction load schedule to reduce voltage losses in the contact network is the use of electricity storage systems. The article presents the results of simulation modeling, which allow us to estimate the change in the energy indicators of an electric train with an increase in movement speeds for conditions of a single electric train following a section. According to the results of traction calculations, the influence of the voltage level on the electric train current collector on the technical speed is shown, the deviation of which for the typical voltage values in high-speed traffic is about 1%. For the selected section of rapid movement and technical speeds, the voltage level for traction calculations is justified. The dependences of the change in the average values of the load and the technical speed with an increase in the maximum speed up to 250 km/h are determined. Statistical estimates for the voltage on the pantograph of the Velaro RUS electric train are determined. The influence of the energy intensity of the onboard storage system with the corresponding charging characteristic on the reduction of maximum currents is shown. Dependences are obtained for the voltage drop on the electric train current collectors with an increase in movement speeds. The assessment of the maximum energy intensity of storage devices for the most severe operating conditions with a single electric train track on the site was carried out. These results allow us to determine the prospects for improving the method of calculating energy indicators and the use of accumulation systems in areas of rapid movement as on-board systems and compare their effectiveness with stationary systems based on simulation modeling, in which various control algorithms are implemented.

The purpose of this work is to determine the causes of cracks in the frame of traction motors of electric locomotives. An analysis of the statistics of detecting cracks in the frame of NB-514 traction motors at the Eastern testing area is presented, showing that every third frame in operation has cracks. The method of mathematical modeling on a computer with the use of FEM was used. It is noted that carrying out measurements in the crack initiation zone by the tensometric method is practically impossible due to the geometry of the frame. The results of mathematical modeling of mechanical stresses arising in the frame of the NB-514 traction motor during its uneven heating to temperatures characteristic of the hourly mode of operation of the traction motor are considered. It is shown that mechanical stresses arising only due to the temperature difference between the ambient air and the windings of the main and additional poles of the traction motor can reach 100 MPa. Variants of changing the design of the ventilation windows of the frame are proposed to reduce the magnitude of temperature stresses with a constant area of the ventilation openings. When correcting the shape of the ventilation windows of the traction motor frame, these voltages can be reduced to 76 MPa. It was concluded that one of the main reasons for the formation of cracks in the frame of traction motors are cyclically repeating temperature stresses, which is especially important for electric locomotives operating on mountain pass sections in the pushing mode. It is noted that the appearance of mechanical stresses in the backbone of the traction motor also depends on vibrations arising from the path and operation of the gear train, as well as on the variable part of the magnetic field of the motor, which are not currently studied in detail.

The article is devoted to the research of the of wind load effect on the aerodynamic component to the movement of a freight train. These findings contribute to a better understanding of the impact of aerodynamic resistance on the consumption of fuel and energy resources (FER) on train traction. The article shows the high significance of this problem for Joint Stock Company Russian Railways (RZD JSC). The conclusions were drawn from the analysis of statistical data on the routes of locomotive drivers, working on the Pallasovka-Verkhniy Baskunchak section, which is undergone to wind loads. The SOLIDWORKS application was used to design a train with a locomotive and gondola cars coupled on an embankment, and SOLIDWORKS Flow Simulation plug-in was used to simulate wind load, different in speed, varying from 0 to 90º. The values of the force of aerodynamic resistance to movement for the train as a whole and for each unit of the rolling stock separately were obtained. Using the methods of the theory of train traction, the influence of aerodynamic drag on fuel consumption for traction has been assessed. Based on the obtained values of the aerodynamic drag forces and patterns of air flow distribution, conclusions were drawn about the effect of loading a gondola car on an increase in traffic resistance. Conclusions are drawn about the effect of wind load on each unit of rolling stock in the train. It was found that when the wind is directed at an angle to the axis of the path, the force of the wind effect increases, compared with the case when the angle between the axis of the path and the velocity vector is zero. The experimental data on the increase in resistance from the wind load are confirmed by theoretical calculation, as well as practical processing of routes machinists. This article demonstrates the need for a separate regulation of fuel and energy resources in the event of wind loads, and may be useful in further detailed study of the aerodynamic drag of freight trains.

The article considers phenomenological and modelling approach to researching of interaction of a deformable wheel and a plane of support, their advantages and disadvantages are mentioned. In the context of phenomenological approach the five methods of locomotive tangent tractive force calculation were considered. There certainly must be pseudo-creeping to let locomotive tangent tractive force do work and change the kinetic energy of a train in the point of wheel and rail contact. Locomotive tractive force experts calculate the power as product of the locomotive tangent tractive force and the velocity of translational motion of a train, although in fact the velocity of the point of force application must be assumed. It is applied to a wheel pair, then the velocity of this point must be used to calculate the locomotive power. According to this fact the locomotive power is found several tens of times reduced.

Based on the analysis of the empty rolling stock on the Krasnoyarsk and East Siberian Railways, the technical parameters that have a significant impact on the unloading of the wheel of the first wheel pair in the course of movement are determined. The design features of wagons influencing the safety coefficient of train traffic are considered. Statistical processing of these gatherings, according to the materials of official investigations, revealed a number of interesting features. One of them is non-normalized total gaps in the sliders along the diagonals of the wagons. This fact in the movement of empty car causes misalignment of the body, which in turn leads to a redistribution of the loads acting on the spring kits on the sides of carts and wagons. The influence of elastic suspension parameters (height, spring break) on the redistribution of loads acting on the sides of the trolley is considered. The misalignment of the body of empty wagons, especially wagons with a sufficiently small mass of unsprung parts and a high center of gravity, leads to a significant reduction in the safety factor. The calculation of the transverse guiding forces acting at the point of contact of the wheel and rail, as well as their effect on the unloading of the wheel. It is revealed that the body skew leads to a significant increase in lateral force, which affects the stability of the empty rolling stock.

Constantly conducted studies of the reliability of electric equipment of traction rolling stock have shown that the most vulnerable element is the insulation design of the windings of power equipment, especially traction motors. Existing methods and means of restoration and repair of insulating structures of windings of traction motors of modern electric locomotives, based on drying polymer insulation in convective high-power electric furnaces, are energy and time-consuming. This technology has not undergone significant changes for over 50 years. In order to extend the polymer insulation life of electric vehicles of traction rolling stock, an insulation drying technology using thermal radiation was proposed that reduces the cost of electricity for repairs and increases the drying speed by reducing heat loss. The article is devoted to the design of a new device for drying the insulation of the windings of the magnetic system of the skeleton of the backbone of the electric locomotive traction engine by a rotating thermal field. The analysis of works and conclusions based on the results of theoretical studies related to mathematical modeling is presented. As a method of mathematical modeling, the finite element method was used in the work. A simplified 3D model of the winding of the core magnetic system with infrared emitters was created. According to the results of finite element mathematical modeling, temperature fields of heating the polymer insulation of the windings of the core of the traction motor were obtained. Based on this calculation, the work selected the optimal design parameters of the proposed device that provide the minimum energy costs for various sizes of the skeleton of the traction engines. Based on the proposed device variant, an application for a patent for a utility model has been filed, and this prototype is being assembled on the basis of the Ulan-Ude locomotive and car repair plant, a branch of Zheldorremmash JSC. New directions for further research are also set.

The article proposes a method of using the mathematical apparatus of the theory of fuzzy sets in automation of the locomotives reliability management, because when writing algorithms there is a problem of transition from not fully formalized concepts of human communication to formalizing software. Examples of the fuzzy sets use in calculating the locomotives reliability are described. When calculating the reliability parameters manually, the volume of calculations does not allow you to move to more complex algorithms. When there are automated systems, it is necessary for each indicator of the transportation process, which affects its reliability, to set the function of belonging to a dangerous and normal value using the mathematical apparatus of the theory of fuzzy sets. Then the risk of a dangerous event will be assessed in probability, taking into account the logical claim to the risk.

An analysis of the operation of electric locomotives on certain sections of railways shows that their power is used irrationally and electric locomotives are operated with low energy indicators, especially on long-distance flat stretches, which indicates that there are reserves for reducing the consumption of electric energy. The purpose of the work is to determine the optimal value of the rated power of electric locomotives by minimizing the electricity consumption on the site and to estimate the loss of electric energy from the non-optimal use of electric locomotives' power. To achieve this goal, an equation was drawn up for the dependence of the electric power consumption on the traction of an electric locomotive on the value of its rated power. To find the optimal value, this equation was differentiated by the value of the rated power of the electric locomotive and solved using the Cardano method. The expression allowed us to determine the minimum consumption of electric power is the rated power of the electric locomotive, depending on the required for a given traffic conditions and to evaluate the variation of energy consumption from non-optimal use of its structural capacity. The obtained equations allowed us to solve the problems of choosing the optimal value of the rated power of electric locomotives and evaluating the irrational consumption of electric energy from the non-optimal use of their power and can be used to determine the optimal parameters of electric locomotives. The conclusion is made about the importance of choosing the optimal power values of electric locomotives in order to obtain the highest technical and economic indicators during their operation.

To increase the speed of the cargo delivery, freight wagons are being developed, intended for the design speed of 140 km/h. One of the important parts of a freight wagon is the bogie, the design of which determines the wagon dynamic behaviour. The bogie of such wagons uses a frame of a rigid design, which is susceptible to antisymmetric loads. The analysis of standards has shown that the strength test during designing a rigid bogie frame under the impact of maximum antisymmetric forces that may occur in operation when a wheel derails is not required, which can lead to a residual antysymmetric deformation of the bogie frame. Theoretical research is performed to estimate the impact of the residual antisymmetric deformation on traffic safety using the wheelset safety factor against derailment. The research results have shown that the bogie frame residual deformation leads to a load redistribution on the wheelset axle journal, which, in terms of the impact on the wheelset safety factor against derailment, is similar to the wagon rolling motion. The wagon rolling motion affects the reduction of the wheelset safety factor against derailment to a greater extent than oscillations during pitching and bouncing. Thus, the permission to operate wagons with the antisymmetric residual deformation of the bogie frame without its non-destructive testing can lead to traffic safety violation. In order to ensure the traffic safety of wagons with bogies having rigid frames and reduce economic losses at the design stage, bogies strength depending on the action of antisymmetric forces should be estimated.

The subjects of the study are the problem of controlling the crew in space by means of an automatic system for controlling the gap between the electromagnet poles and ferro-rails in the system of high-speed land transport based on the levitation effect. One of the main conditions for comfortable levitation mode of the crew is the absence of vertical deformations of the crew during multipoint suspension due to non-uniform distribution of lifting and guiding forces. In order to ensure the stability of the crew's electromagnetic suspension, various combinations of control system feedbacks are proposed. The results of the study of the electromagnetic suspension control system using the electromagnet current feedback in the land speed vehicle levitation mode are presented. The main requirement to the control system of an electromagnetic suspension in the levitation mode is the maximum permissible deviation of the permissible air gap ±5 mm under the action of the impulse of the aerodynamic force in the horizontal plane and the speed of its application. The principle of subordinate regulation of the control system parameters with the use of regulators in accordance with the functional two-loop system of automatic regulation with current feedback has been proposed. The application of the double-loop automatic control system at supply voltage fluctuations corrects the electromagnet current and excludes the deviation of the maximum permissible gap between the electromagnet and the ferro-rail. The performed calculations prove that the introduction of the electromagnet current feedback decreases the velocity transfer coefficients and thus increases the signal speed.

One of the properties of the reliability of the power supply of electric rolling stock of railways is the trouble-free operation of the traction power supply system in various modes of its operation. For post-emergency and forced modes of operation of the traction power supply system, a decrease in load capacity is characteristic. In order to ensure the throughput and carrying capacity of the railway section by traction power supply devices, it is proposed to consider the use of electric power storage devices on electric rolling stock and in the traction power supply system.

Modeling of changes in the modes of operation of the traction power supply system is carried out taking into account the state control of switching devices. The calculation results allow us to estimate the voltage drop at the output of electric power storage devices, including taking into account the exponential zone of the discharge characteristics of batteries, to estimate the voltage change for a given electric traction load depending on the energy intensity of the storage device, made on the basis of the most common types of batteries and a supercapacitor.

The developed proposals will allow increasing the energy efficiency of passenger DC electric locomotives.

Railway transport faces the challenges not only to ensure uninterrupted transportation of national economic goods, but also to develop new locomotives and increase the efficiency of their use. In particular, the currently accepted mode of starting diesel locomotives of the UzTE16M type leads to additional consumption of fuel resources, therefore, research on the development and improvement of the conditions for starting diesel locomotives of this type is relevant. Based on the study of previous studies and designs of various systems in order to facilitate the start of diesel locomotives with electric transmission, it is necessary to establish the available reserves of the power circuit and control circuits. The article considers a mathematical model of torsional oscillations in a diesel generator start-up system with two concentrated mass moments of inertia. Torsional oscillations between the traction generator and the crankshaft of diesel locomotives of the UzTE16M type have not been previously considered. In this article, the problem of torsional oscillations of the reduced masses of the armature of the traction generator and diesel engine in the mode of starting the DG from the battery and additional devices is solved. The Lagrange method has derived a system of mass oscillation equations based on generalized coordinates of elastic oscillations between the masses of the armature of a traction generator and a diesel engine with a variable mass moment of inertia. For the resulting system of equations, the solution is performed by the method of operational calculus, taking into account the accepted functions of mass moments of inertia, moments of driving forces and resistances. Conclusions are drawn that the operation of the diesel starting system on diesel locomotives of the UzTE16M type is determined by the functions of the reduced mass moment of inertia of the diesel, the driving torque and the angular velocity function; the resulting solution makes it possible to calculate the driving torque and the range of angular velocity changes when starting the diesel generator set of UzTE16M locomotives for further comparison with experimental data; when using the recommended electric scheme for starting a diesel locomotive, an increase in the driving torque of the diesel crankshaft and the angular acceleration speed of the traction generator armature is achieved. Based on the developed model, it is recommended to determine the angular velocity of the diesel crankshaft.

Measures to normalize the consumption of diesel fuel for the operation of shunting locomotives are an integral part of the efficiency of the use of traction rolling stock. Due to the presence of problems in the formation of the fuel consumption rate, such as the performance of the shunting locomotive, the loading and technical condition of the diesel generator set, the operating conditions of locomotives, it is necessary to improve the existing fuel consumption rate determining methodology. The article presents the results of studies of the operating modes of shunting locomotives, the parameters of the spread of the values of the operating time of the diesel generator set in the load mode for shunting locomotives of the TEM2 and TEM18DM series are given. A mathematical model based on the bases of machine learning models is proposed, taking into account the degree of loading of the diesel generator set and the technical and economic characteristics of the locomotive series. The task of the proposed model is to determine the fuel consumption of a locomotive by an iterative calculation method, where the input parameters of the model are the performance indicators of the locomotive. It is established that the method of forming the fuel consumption rate for performing shunting operations should take into account the degree of loading of the diesel generator set and the technical and economic characteristics of the locomotive series. According to the results of the implementation of the proposed model for establishing specific fuel consumption rates for the studied locomotives based on the results of their operation, the average indicators of specific fuel consumption by locomotives by the positions of the driver's controller are obtained. The proposed method allows us to take into account the actual degree of loading of the diesel generator set and establish the correct fuel consumption rate for a certain period of operation of the locomotive, which represents the practical significance of the work. The presented research results are the beginning of work on the development of an intelligent system for diesel fuel rate rationing for the operation of shunting locomotives.

The article considers a suitability of mathematical model of stretched rod to determine the relationship of the parameters oscillations of the contact wires and their tension. This model allows you to determine the tension by the frequency oscillations of the contact wire obtained after the passage of the current collector. In this case, the speed of the electric rolling stock will not affect the frequency of the damped oscillations.

The article analyzes the test schemes of induction traction motors by the mutual load method using DC generators as load machines and powered by a three-phase AC network with a frequency of 50 Hz. Features of functioning of each of the given schemes of mutual loading are considered. The disadvantages of these schemes are noted, due to the presence of excess equipment or the lack of short-circuit protection in the anchor circuit of the load generator and the complexity of its connection to the DC link. The scheme developed by the authors is proposed, devoid of the noted disadvantages of the known schemes and combining all their advantages, which is the simplest both in the power part and in controlling the process of connecting the armature winding to the DC link of a frequency Converter. A mathematical model of a test system consisting of an induction traction motor, a DC load generator and a two-link static frequency Converter is presented. The mathematical model of this test system is made up of parts corresponding to its individual elements. The presented mathematical model makes it possible to calculate the static and dynamic operating modes of the proposed scheme at the stage of development of an electrical complex for testing induction traction motors. Recommendations on the implementation of developments in the operation of induction traction motors in locomotive repair depots are given. The expediency of implementing the results of work in organizations-developers of test stations for induction traction motors is also noted.

The subject of the study is energy efficiency of traction power supply system and traction electric drive of electric locomotives. The article is scientifically based on the assessment of the energy efficiency of the mutually connected system of electric traction of trains. The study is aimed at solving problems on reduction of voltage losses in the contact system, active power in the contact system and traction electric drive of electric locomotives. This is possible due to the full and continuous use of the electrical potential of the power supply system. The research methodology is based on the law of energy preservation, mathematical modeling of the energy process and spectral analysis of voltage and current on the current collector of the electric locomotive. Analytically and by results of calculation it has been proved that significant losses of voltage, active power in the contact system, traction electric drive of electric locomotives are caused by unsatisfactory operation of power regulators and mismatch of voltage level in the contact power network, which is necessary for realization of heavy and high-speed driving of trains. In order to eliminate the negative effect of the inductive coupling of AC traction power supply on the energy efficiency and speed of trains, it is proposed to increase the voltage in the DC contact system and develop power regulators of electric locomotives. Mathematical model of DC electric traction system shows possibilities of reduction of electric energy losses and increase of movement speed due to application of electric semiconductor variator for matching of high voltage in contact system with voltage of traction electric motors of electric locomotive.

The subject of the study is the process of applying optical technologies for non-contact measurements of geometric parameters of a wagon wheelset during operation and repair. The purpose of the study is to study the methods of field testing of technologies for controlling the geometric parameters of car parts using an optical rangefinder, with mutual verification of the results obtained using numerical modeling using three-dimensional digital models of objects and measuring instruments. As a result of the study, experimental and calculated dependences of the optical sensor readings were obtained during the change in the relative position of the measuring object (wheelset) and the rangefinder. Two laser triangulation rangefinders were used for field tests. For numerical simulation, a program was created that allows generating a three-dimensional model of the rolling surface of a wheelset consisting of a set of points belonging to the surface of rotation. The simulation consists in finding the intersection points of a line defined using the coordinates of the point of the radiation source in space and the guiding vector with the model of the skating surface. After the calculations, the result is given in the form of a table with calculated ranges and visualized as projections of a three-dimensional wire model of a wheel and a rangefinder beam. Visualization of the numerical modeling process is important to avoid misinterpretation of the calculation results and to verify compliance with the physical meaning of the numerical data obtained during modeling. Comparison of graphs shows the convergence of the results and sufficient accuracy of numerical models and techniques that can be used in the future to plan full-scale tests of the designed techniques and equipment for dimensional control of railway car parts.

A variant of application of a contact compensated chain suspension with levers and lateral current collection for a three-phase traction power supply system (TSTE) is considered. Two different-phase contact suspensions are located on different sides of the track axis. The electric rolling stock must have two current collectors that press on the contact wire from the track axis in opposite directions. The description of the design of the contact suspension as a whole and the main components, in particular, the fastening of the rods, which makes it possible to provide a vertical zigzag and limit the transverse movement of the contact wire, is made. At points at the supports, the levers are connected to the consoles and have a knot to create angular rigidity. In addition, the rotation of these levers is limited towards the axis of the path and in the opposite direction. This prevents the possibility of lashing of different-phase contact wires. In accordance with this design, a mathematical model of this contact suspension was developed based on the finite element method, which provides calculation in statics and dynamics, taking into account the current collector. To describe the pantograph, a common three-mass model is used. Based on the analysis of the results obtained using this model, the influence of the design parameters of the suspension, cross wind and the speed of the pantograph movement on the quality of the current collection is determined, the limits of applicability of the suspension under consideration, depending on the value of these parameters, are established. It has been determined that, in contrast to a conventional contact suspension with a vertical current collection, for suspensions with a lateral current collection, a side wind has a significant effect on the quality of the current collection. It is the wind speed that is the main factor limiting the possibility of using a suspension with lateral current collection.

The work relates to the application of a new method of noncontact RFID monitoring of the condition of insulators for overhead power lines, including signaling, centralizing, blocking, and longitudinal power supply lines . A significant number of accidents occur due to the breakdown of insulators and imperfection of control methods. It is proposed to use a non-contact RFID control system for overhead power line insulators, which consists of a reader with a transceiver and an antenna, standard insulators with RFID indicators and special software. The aim of the research is the influence of climatic factors on the components and assembly structures of pin insulators with RFID indicators and the operation of the RFID control system in general. The selected study samples are a radio frequency tag, an aluminum-coated plastic cap with an integrated tag, and a pin-shaped porcelain insulator with an RFID indicator in the assembly. The climatic tests were carried out in the testing center of technical means of railway transport of the Ural State University of Railway Transport (IC TSZHT USUPS). Temperature changes were simulated from -60 to +50 ° С with air humidity up to 93%. The results on the adhesive properties and electrical conductivity of a conductive coating on a polyethylene surface and the stability of the functioning of RFID tags are presented and analyzed. Suggestions for improving the components and assembly design are given. Firstly, to use a screw thread on the top of the pin instead of a special knurling, which will reduce mechanical stress during installation of the structure of individual components and will reduce the error in the installation dimensions to improve the reception and transmission of signals between the reader and the tag. Secondly, sandblasting of the surface of the polyethylene cap can improve the adhesion of the surface to the conductive coating, which will increase the electrical conductivity of the structure. The result of this work proves that the developed RFID control system of insulators functions in the climatic conditions specified by GOST, which allows to recommend its implementation in the lines ts use in lines of devices with a voltage of 6-10 and 35 kV.
