Abstract

Background: The methods of calculation and elements of the technology for creating heteropolar magnetic systems of levitation, lateral stabilization and a rotor-runner of a traction linear synchronous motor for the development of the transport technology "Russian Maglev" in order to achieve an increased levitation gap of 0.2 m, reduce the threshold speed of the exit vehicle in levitation mode up to 10 km/h.
 Aim: to develop methods for calculating and designing heteropolar poles from elementary permanent magnets, coils of the same type based on composite low-temperature superconductors and high-temperature tape superconductors of the second generation and a step-by-step technology for their production.
 Tasks:
 
 Creation of an on-board magnetic system of levitation and lateral stabilization, allowing to provide a levitation gap of 0.2 m, a threshold value of vehicle speed of 10 km/h when transition to levitation mode, to reduce stray magnetic fields to the level of the natural field of terrestrial magnetism of 50 T;
 Creation of a rotor-runner of a linear synchronous motor with an ironless stator with a power of 10 MW.
 
 Methods: outlines the main calculation methodologies: "analysis" and "synthesis". The "analysis" methodology is adopted in solving the "direct" calculation problem, when the configuration of the magnetic system is set and the magnetic field in the working area is calculated, and, if necessary, the stray magnetic fields. This methodology can be effectively applied if there is experience in creating magnetic systems. Otherwise, the "synthesis" methodology is applied, which is used in solving the "inverse" calculation problem, in which the picture of the distribution of the magnetic field in the working zone is set and the configuration of the magnetic system is found (synthesized).
 Results of the study performed:
 
 The parameters and characteristics of high-energy permanent magnets made of rare-earth metals, low-temperature and high-temperature superconducting winding materials have been analyzed, the choice of permanent magnets and superconducting winding material has been made;
 Calculations of the magnetic system of permanent magnets in the "Halbach assembly" and in the traditional assembly in a toothed ferromagnetic core have been carried out;
 Calculations of a track coil with a rectangular cross-section of the winding are performed;
 Methods for calculating and optimizing superconducting magnetic systems from a set of similar track modules have been developed;
 
 Conclusions: The results of the performed fundamental research will allow starting the calculation, design and construction of conveyor-main passenger and freight lines of maglev transport, as well as urban public transport.

ОРИГИНАЛЬНЫЕ СТАТЬИ ORIGINAL STUDIES

Обоснование: Излагаются методы расчета и элементы технологии создания гетерополярных магнитных систем левитации, боковой стабилизации и ротора-бегуна тягового линейного синхронного двигателя для развития транспортной технологии «Российский Маглев» с целью достижения повышенного левитационного зазора 0,2 м, снижения пороговой скорости движения транспортного средства выхода в режим левитации до 10 км/ч. Методология «анализ» примняется в решении «прямой» задачи расчета, когда задается конфигурация магнитной системы и рассчитывается магнитное поле в рабочей зоне, а, при необходимости, магнитные поля рассеяния. В противном случае применяется методология «синтез» для решения «обратной» задачи расчета, в которой задается картина распределения магнитного поля в рабочей зоне и находится (синтезируется) конфигурация магнитной системы. Разработаны методы расчета и оптимизации сверхпроводниковых магнитных систем из набора однотипных трековых модулей; Выводы: Результаты выполненных фундаментальных исследований позволят приступить к расчету, проектированию и строительству конвейерно-магистральных пассажирских и грузовых линий магнитолевитационного транспорта, а также городского общественного транспорта.
