ISOLINE OF THE BORDER OF NAVIGATION SAFETY ZONE OF A VESSEL
Authors: Garashchenko M. A.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT Prevention of the majority of emergency situations in navigation is based on observing a certain distance between vessels, which allows timely taking precautionary measures in order to avoid contact. The thus created conditional space of safety distances forms a navigation safety zone. The article gives a universal conceptual definition of such a zone, a generalized structural classification of factors affecting its size and shape, the nature of the isolinear zonal boundary. The concepts of isoasphalia as an idealized safe boundary, as well as an isoasphalic surface forming an idealized safe area around the vessel are introduced. On the basis of set theory, a variational law of variation of piecewise functions describing a safe space asymmetric with respect to the vessel’s diametric plane is derived. The resulting expression allows us to identify the boundary of an asymmetric elliptical navigation safety zone. Keywords: sea vessels, navigation safety, idealized model, isoline boundary, isoashpalia, isoasphalic surface, asymmetric elliptic zone, set theory, variational law.

INTERACTION OF A WHEEL WITH A RAIL DURING ROLLING
Authors: Pisarenko V. V.
Published: October 2022

[For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version)].ABSTRACT The problem of uneven wear of a wheel set is considered by many scientists of the world, in the works related to car building. New software complexes for mathematical modeling are being created, and each follows its own theory of rolling stock dynamics. In this article the main provisions for deformation and wear of a wheel along the circle of rolling during car movement are considered. In this case, the elastic sliding model is described in more detail. During wheel rolling and in the presence of torque in the contact area, there is always a gripping area that is located at the entrance, and an area of slippage at the exit. It is proved that the coefficient of slippage is equal to deformation in the gripping area. Under certain kinematic and dynamic conditions, a stress distribution graph is plotted in the contact zone. On the basis of the theory of tangential stresses, a displacement formula is obtained, which is transformed into a new formula for the creep coefficient, which retains the physical meaning of the value found. Keywords: theory of rolling stock dynamics, wheel set, rail, creep coefficient, sliding, gripping, contact spot, wheel rolling, stress distribution.

For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version). ABSTRACT The article proposes authors’ design to reduce the temperature of exhaust gases on the surface of pipelines of the resonator and the catalyst. To do so plates of various geometric shapes and sizes are arranged perpendicularly and (or) at an angle to their longitudinal axis, spaced apart from each other. The expediency of using this variant of modernization of the exhaust system of the internal combustion engine is supported by theoretical and experimental studies, the reliability of which is confirmed with a confidence probability of 0,95. The regression dependencies obtained give grounds for recommending their own order of regulating the rate of cooling of a pipeline that removes exhaust gases, in accordance with their initial parameters and subsequent dynamics of indicators. In addition, during the experiment it was possible to reveal the physical picture of the process of heating and cooling of a pipeline along its length.

USING PLUGINS IN BIM-PROGRAMS WHEN DESIGNING BRIDGE ELEMENTS
Authors: Kyaw Z. A.
Published: October 2022

For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version). ABSTRACT The article considers an example of extending the program for information modeling of elements of the metal bridge. Over just the past few years there has been a significant progress and qualitative leap in design of building structures transforming it from twodimensional drawings to information modeling (BIM technology). This transition became possible due to modern software. Unlike the creation of twodimensional drawings and three-dimensional model of the construction in the CAD system, the process of information modeling creates a database that contains information about each element of the building. This approach allows to store and modify information about the object throughout the whole lifecycle of the project. Revit and Tekla are the most popular products in Russia. With their help it takes little time to assemble an information model for a typical building because these programs contain large libraries with the elements. However, when designing a unique building it is necessary to add new elements and plug-ins (extensions) to the program. Plug-ins can significantly reduce the design time. Almost all of the programs for BIM allow the usage of such extensions. Tekla has a very convenient functionality for automation. With this program it is possible to extend the functionality using the Tekla Open API, which uses C# programming language. The article considers the automation process of placing the bolts in the nodes of the main through trusses of the metal bridge. To achieve this, a C# program (plug-in) that performs the placing of the bolts has been created. Examples of dialog boxes created with the help of the Tekla Open API that illustrate the implementation of the proposed algorithm are provided. Keywords: information model, computer-aided design system, BIM-technologies, Open API interface, adaptation, plug-in, truss, node, bridge.

ABSTRACT The current problems of increasing the efficiency of optoelectronic devices with the help of new materials are considered in the article. It is noted that the most promising direction of research is the design of semiconductor materials using the own isotopes of chemical elements. Thus, purification from heavy isotopes increases the speed of optoelectronic devices, quantum efficiency, sensitivity of photodetectors. The greatest effect of isotope purification can be obtained for a nanostructured material (superlattices). This new semiconductor material will create more sensitive instruments for night vision, solar panels, safety systems, medical equipment, ultra-long-range infrared photodetectors. Keywords: optoelectronics, communication, isotopes, purification, quantum efficiency, superlattices.

ON THE PROBLEM OF NONLINEAR WAVES IN RODS
Authors: Vakulenko S. P. , Volosova A. K. , Volosova N. K.
Published: October 2022

For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT The article shows new, nonclassical dispersion waves and vibrations, and their spectrum is studied for two reasons: firstly, there is an increase in the number of composite materials used in railway transport, which leads to the phenomenon of dispersion, and secondly, the spring of 2017 showed that many kilometers of tracks were flooded with shallow water. The task of detecting a track defect and determining its spatial localization can be solved with the help of measuring the energy of longitudinal, vertical and transverse oscillations. But the phenomenon of dispersion makes it very difficult to detect the occurrence of new track defects from the rolling stock (see World of Transport and Transportation, 2016, Vol. 14, Iss. 3). The method of «unfixed constructive change of variables» is used in the paper. The authors conclude that two necessary conditions for the solvability of a system of differential equations with first-order partial derivatives have one common nontrivial factor; and that through designing new exact solutions of the non-linear KdV equation that differ from the classical ones, it is found that there is a change of variables in which the equation for the function Y(ξ, d) = Y0(U(ξ, d), ξ) is separate from all the others. Keywords: railway track, vibration spectrum, diagnostic system, Korteweg-de Vries equations, method of non-fixed constructive change of variables. Acknowledgements.

For the English abstract and full text of the article please see the attached PDF-File (English version follows Russian version).ABSTRACT The international transport route using transit possibilities of Iran within the framework of the corridor «North-South» is a project, the urgency of which is conditioned by the processes of intensification of trade and economic relations between the countries of the Eurasian continent. ITC provides delivery of cargo from India, the Persian Gulf zone, Iran to the territory of Azerbaijan, Russia and then to Northern and Western Europe. In particular, rail transportation along this route will shorten the transportation time from 45-60 to 20-25 days compared to the way from the Baltic through the Mediterranean, the Suez Canal and the Persian Gulf. Such a change in logistics reduces transportation costs by 10-15 %. The prospective volume of container traffic is estimated at 3,5 million containers in a twenty-foot equivalent. Keywords: multimodal transportation, corridor «North-South», transport infrastructure, transport and logistics system, Caspian logistics cluster.
