Simulation of the maglev suspension dynamic characteristics during movement, acceleration and deceleration
Martirosian I.V., Pokrovskii S.V., Osipov M.A., Starikovskii A.S., Rudnev I.A.
Abstract

Background: When developing high-speed transport systems based on the magnetic levitation phenomenon, it is necessary to take into account a huge number of factors that affect the characteristics and stability of this type systems. One of the simplest and most convenient methods for achieving these goals is numerical simulation.

Aim: simulation of the dynamic characteristics of a magnetic suspension based on a high-temperature superconductor during movement, acceleration and deceleration.

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

Results: during straight motion, lateral vibrations do not exceed 15 %, and the suspension speed and mass increase does not have a significant effect on the vibrations amplitude. In the case of vertical oscillations, the platform mass and speed increase leads to an increase in the vibration resistance of the system. With an increase in the turning radius of the track, the maximum possible speed of entering the turn without detaching the suspension from the magnetic track increases non-linearly.

Conclusion: The developed numerical model makes it possible to predict the dynamic characteristics of levitation transport and can be applied to systems of various scales.

Kireev A.V., Kozhemyaka N.М., Kononov G.N.
Abstract

Background: The paper discusses the features of building a control system for an electro-magnetic suspension of a cargo platform. The operating conditions of cargo systems are associated with a large range of changes in the mass of the cargo and an abrupt change in the voltage of the power source. The control structure of the electromagnetic suspension system contains a non-linear unstable object (electromagnet). This greatly complicates the management process.

Aim: The aim of the work is to study the properties of an unstable control object for its representation by an equivalent linear model, which makes it possible to automate the process of controller synthesis in the MATLAB software environment.

Methods. The main research methods are computer modeling, computational studies, analysis of research results.

Results: An approach to the construction of an adaptive control system for an electromagnetic suspension based on the synthesis of a linear controller based on an equivalent linear model of an unstable object is proposed.

Conclusion: The practical significance lies in the fact that the proposed approach can be used to design a control system for the electromagnetic suspension of a cargo platform.

Features of the assessment of socio-economic effects arising from the construction of lines of freight maglev transport
Smirnov S.A., Smirnova O.Y.
Abstract

Background: Transport is a sector of the economy that is subject to general economic laws, including with regard to issues related to investing in real assets, developing means of production, and ensuring expanded reproduction. Along with this, transport is a strategic sector at the state level, ensuring the functioning of the economy as a whole. In this regard, there are certain contradictions associated with the assessment of the effectiveness of investments in transport infrastructure. In most cases, investments in transport infrastructure are valued similarly to investments in a business project. After the issuance of Decree of the Government of the Russian Federation No. 1512 dated November 26, 2019, the approach to evaluating the effectiveness of investments with state participation has expanded, but it does not fully cover the issues of project effectiveness for the state. Along with this, the classical methods for evaluating the effectiveness of investment projects are subject to great subjectivity in relation to the calculation of social effects, as a result of which their applicability to projects at the national economic level is ineffective.

Aim: to consider the list of effects arising from the construction of transport infrastructure and determine the methodology for calculating the effects for the state.

Materials and methods: the research methodology is based on the analysis of methods for financial and economic evaluation of investment projects, as well as macroeconomic methods. The information base of the study is based on the official legal and methodological information of the authorities of the Russian Federation.

Results: as a result of the study, a list of effects for the state arising from the implementation of transport infrastructure development projects was determined, and the procedure for their calculation was substantiated.

Conclusion: the study confirms that the currently used methods for evaluating the effectiveness of investments in infrastructure projects for the state do not fully and objectively reflect economic realities. The proposed approach to the assessment will make it possible to carry out a comprehensive assessment of the socio-economic effects from the construction of cargo maglev transport lines and improve the quality of management decisions in the transport sector.
