Method for Calculating the Beam Span Structure During Motion of the Magnetic Levitation Transport

Abstract

Magnetic levation transport technology has great potential for implementation in the transport complex of Russia. Development of technical conditions and normative documentation is an integral step for the introduction of these innovations. This article proposes a computational model of a magnetic levitational train, which gives an idea of maglev train dynamic effect nature on bridge structures. The importance of this issue is due to the fact that in the construction of high-speed railways on overpasses is preferable to the ground version and the increase in construction costs caused by the need to strengthen the span structures for passing high-speed trains reduces the attractiveness of projects. Based on the results of calculations, conclusions about the significant difference in the nature of the transfer of loads from maglev trains to infrastructure in comparison with the conventional wheel-rail technology were made. Maglev trains allow to move at significantly higher speeds without a multiple increase in the dynamic ratio for bridge structures. The calculation model proposed in this article confirm the possibility of reducing costs for the transport infrastructure for magnetic levitation transport. The article outlines vectors of application and optimization of this model and draws conclusions about basic directions of further research in field of creation a regulatory and legal framework for this new type of transport in Russian conditions.
