Experimental study of the mixing process of asphalt concrete mixtures
Vasilev K.A., Averchenko G.A.
Abstract

The process of mixing mineral components with organic binders in the technology of preparation of hot asphalt concrete mixtures is considered. As a working hypothesis, the assumption of a functional relationship between the power consumption of the electric motor of the agitator and the mixing resistance is accepted. It is necessary to establish the dependence of the power consumption of the agitator drive on various technological parameters. Experiments were carried out: in laboratory and production conditions, which showed fairly simple dependencies.

The impact of natural factors on the condition of roads in various regions of Russia
Alekseev S.V., Simonov D.L., Katikova A.S.
Abstract

The article is devoted to the peculiarities of taking into account natural and climatic conditions when designing a highway. It is shown that environmental conditions directly affect the specifics of the designed roads. However, they can play a dual role: both to promote and counteract the long service life of the roadbed. Since it is impossible to influence the weather conditions, it is necessary to provide full protection of the highway. All factors affecting the road condition at the early stages of design were analyzed. It is concluded that if the regulatory and technical requirements are not met, the quality and safety of the road will not be ensured for each road and climate area.in this regard, the most effective methods of protecting and reducing the negative effects of environmental impact were considered.

Martirosian I.V., Osipov M.A., Starikovskii A.S., Pokrovskii S.V., Rudnev I.A.
Abstract

Background: analysis of the influence of cooling conditions of high-temperature superconducting elements on the power characteristics of a maglev system under conditions of rapidly changing magnetic fields

Aim: analysis of the influence of cooling conditions of high-temperature superconducting elements on the force characteristics of a magnetic-levitation transport platform under conditions of rapidly changing magnetic fields caused by the inhomogeneity of the magnetic track.

Methods: numerical analysis of the maglev system was performed by the finite element method in the Comsol Multiphysics engineering simulation software.

Results: at fast, more than 5 T/s, magnetic field change rates, due to the motion of the superconductor in a magnetic field with a non-uniform local distribution, the preferred method of cooling is the use of cryocooler technology. At rates of change of the magnetic field less than 5 T/s, it is permissible to use liquid nitrogen as a cooler.

Conclusion: The developed numerical model makes it possible to predict the dynamic characteristics of levitation systems of various scales and can be applied to contactless transport, as well as in rotating machines, including kinetic energy storage devices.

Sirotkin V.V., Pigalev D.A., Bol'shikh I.V., Chernyaev S.S.
Abstract

Background: The article describes the process of occurrence of additional losses in the extreme turns of the copper stator windings, based on physical laws. The causes of the skin effect in the stator windings of a switched reluctance motor (SRM) are presented, an assessment of the skin effect influence degree on additional losses in the SRM of medium and high power. 2D-model of the SRM sector in “COMSOL Multiphysics” software package is created to specify distribution of magnetic field in the SRM stator windings and to quantify the amount of additional losses. А comparison of the magnetic field distribution of the SRM configuration 12/8 obtained in the “FEMM” program and the SRM magnetic field distribution built in “COMSOL Multiphysics” software package is presented to assess the reliability of the results.

Aim: Calculation of the magnetic field distribution in the turns of the stator winding by building a phased 2D-model of the SRM sector (pole division) in “COMSOL Multiphysics” software package to quantify the amount of additional losses caused by eddy currents in the windings.

Methods: “COMSOL Multiphysics” software package is used to build 2D-sector of the SRM. To obtain results on the distribution of electromagnetic fields within the simulated area, finite element methods (FEM) are used to estimate income adjustments, the results are compared with calculations in the “FEMM” program.

Results: The patterns of the magnetic field distribution of the SRM obtained in “COMSOL Multiphysics” software package and in “FEMM” program confirm the presence of a skin-effect in the extreme turns of the stator winding. It can reduce the energy efficiency of the SRM and cause local overheating of the winding turns. As a result of the simulation, the picture of the magnetic field distribution of the SRM obtained in the “FEMM” program is similar to the picture of the magnetic field distribution of the SRM obtained in “COMSOL Multiphysics” software package. Ratio error of the values of the magnetic induction of different parts of the SRM is 3–7 %. It is acceptable and it indicates the correctness of computer modeling in “COMSOL Multiphysics” software package.

Conclusion: The patterns of the magnetic field distribution SRM in “COMSOL Multiphysics” software package and in the “FEMM” program confirm the presence of the skin-effect in the extreme turns of the stator winding, which will allow further research in the field of determining the numerical values of additional losses using 2D-model, and proceed from 2D-model to 3D-model of the SRM.

Nezevak V.L., Dmitriev A.D.
Abstract

Background: the determination of the energy indicators of the traction power supply system based on the train schedule in the conditions of operation of storage devices is based on the solution of a number of instantaneous schemes, each of which corresponds to the established operating mode. These methods require adaptation to account for non-linear characteristics or indicators, the value of which is associated with the retrospective of the change. In this regard, it is necessary to use calculation methods based on the solution of differential equations to solve problems related to the assessment of performance in transient or emergency modes, taking into account dynamic characteristics. Modeling the operation of storage devices in the traction power supply system allows you to evaluate the change in indicators depending on the parameters of the devices, traction load and circuit solutions for various topologies.

Aim: to determine the structure of models of electric power storage devices in DC and AC traction power supply systems, to consider the results of calculating the main energy indicators, to determine ways to improve circuit solutions based on the identified features, to determine the technical requirements for electric power storage devices in traction power supply.

Materials and Methods: to obtain the results, methods for solving differential equations corresponding to various variants of the topology of storage devices in traction power supply, implemented in the Matlab software package, are used.

Results: the results obtained allow us to determine the structure of storage devices for traction power supply, evaluate models of devices for traction power supply of direct and alternating current, outline the prospects for further research in the field of circuit solutions and required device parameters.

Conclusion: the results of the study allow models of electricity storage devices and technical solutions for their implementation aimed at introducing DC and AC traction power supply into the system.

Оn the issue of the development of permanent magnet suspension systems for transport systems
Kim K.K., Karpova I.M.
Abstract

Aim: to develop recommendations for the development of optimal design schemes of permanent magnet systems designed to create a suspension force.

Methods: we described the electromagnetic interaction in the system using classical field theory, the principle of superposition was used, the forces were calculated using the method of mirror images and Chebyshev quadrature formulas.

Results: an increase of the number of rows of magnets with alternating polarity leads to an increase in the resulting strength of the demagnetizing field and there is the opposite effect in the case without alternating polarities. The suspension force reaches its maximum at a certain distance between the rows of permanent magnets. The side force reaches a maximum at a certain amount of transverse displacement in the horizontal suspension system. The control of the loading capacity of the suspension by changing the size of the cross sections of permanent magnets is accompanied by an increase their mass of the magnetic material. The presence of a ferromagnetic buss significantly improves the characteristics of the suspension and has a beneficial effect on the stability of the suspension.

Conclusion: it is advisable to use multi-row structures on the track and on the vehicle with a certain step of installing magnetic rows with alternating polarity and the distance between the rows affects the magnitude of electromagnetic forces. The choice of the cross-sectional dimensions of permanent magnets should be carried out taking into account the specific requirements for the suspension system, taking into account the reversibility of the remagnetization process.

Unitsky A.E., Khlebus A.S., Ivanova E.A., Shashko A.E., Tsyrlin M.I.
Abstract

Rationale: Development of string rails with low weight per meter and high-performance characteristics that determine durability, wear resistance, reliable grip of vehicle wheels to the rail rolling surface is a vital task.

Objective: to investigate impact of the geometric parameters of the steel wheel and the flexible string rail with a polymer coating on the performance characteristics; to choose the most optimal parameters of the contact pair “wheel-rail”.

Methods: The calculation was made using the ANSYS finite element analysis software package.

Results: in order to reduce the level of contact pressures, it is more expedient to lower  the load on the wheel or increase the width of the contact, rather than to increase the radius of the wheel; the most optimal is the contact pair, where the modulus of elasticity of the polymer rail head is equal to the modulus of elasticity of the wheel material, that is, materials similar in elasticity are used in the contact pair.
