5-th International Scientific Conference

5-th International Scientific Conference
"Magnetic Levitation Transport Systems and Technologies"
to be held in Alexander I Petersburg State Transport University

24-26 May 2017

The expected number of participants is 140, 20 of them experts from other cities, and 9 foreign experts from Germany, China, Brazil and Ukraine.
The MTST’17 Conference is dedicated to solving the following fundamental scientific problems: developing the fundamental basis to offer national Maglev technologies to build, certify and operate commercially conveyor mainline freight and intercity passenger lines and communal transportation lines in megapolises.
The event to be held will promote solving the following specific tasks: permanent levitation, design and testing of unified superconductor modules for systems of magnetic levitation, lateral stabilisation and linear traction of a freight transportation vehicle, transportation vehicle stability in closed (technical vacuum) and open spaces.
Physical principles will be reviewed of magnetodynamic levitation and electrodynamic braking. Options were studied of building discrete levitation tracks using transverse Gramme ring coils and distributed squirrel-cage windings. Levitation unit designs schemes will be offered that reduce the initial speed of a transportation vehicle at which levitation starts by an order of magnitude, with minimum use of active materials. Discussion will be focused on the similarity between the levitation unit and the track built as an expanded squirrel-cage winding and an asynch motor with short-circuited (solid) rotor as well as the similarity between the physical processes and operation modes of an async motor and a levitation unit. The basic theoretical premises will be offered which are designed for an async motor with short-circuited rotor and the relevant computational formulas available for adaptation to describe the operation of the levitation unit. First of all, these relate to the electromagnetic momentum generated by the levitation unit, which in our case works as a brake. Since the discrete levitation rail track (winding) is permanently fixed, processes occurring in the levitation unit are similar to those in an async motor with short-circuited locked rotor. Computation relationships available from the theory of async machines are adapted to describe the levitation effect and electrodynamic braking of Maglev transportation vehicles.
Maglev transport is usually for passenger transportation. However, the analysis of highway freight operations along the Saint Petersburg – Moscow route demonstrates that Maglev transport may be in demand on the market of intercity freight operations, container traffic first of all. The scope of cargo traffic along that route is characterised by the following indicators. Marine ports of Saint Petersburg and the Leningrad region ship more than 1.8 million containers to Moscow annually. More than 90% of that traffic is by trucks. Five years from now, the number of containers shipped will reach 4.5 million. Expert assessments show that the existing surface transport system based on rail and truck transport will fail to cope with the cargo traffic in the near future. Additionally, transportation problems will become quite sensitive socially. Transportation costs become significant in the final commodity price. It may be double the wholesale manufacturer’s marketing prices.
Introducing Maglev transport technologies will stimulate highly intellectual science and production potential by developing national basic and applied science and the vocational higher school, forming the national design enterprises and starting high-tech production of state-of-the-art transport vehicles of global level.
Operating Maglev transport envisages development and broad implementation of satellite navigation technologies to support the diagnostics, communication, land and on-board automatic control in accordance with the international IRIS standard that will need relevant updating.
