Research About High-Speed Maglev-Railway On The Relation Of Speed Target And Building Cost

With the development of the economy, science and technology, the society put forward stricter require for the travel speed and comfort. The transportation vehicles such as airplanes, cars, trains and so on, have creating new reports continually, at the same time, the maglev railway which as a new type of transportation vehicle becomes a technology mature and credible form the initial tentative plan. Today with the merits of speediness, economy, safety and comfort, the maglev railway has breaking new foreground for railway traffic.The speed target of high-speed maglev railway has been designed at 400～500km. p. h. therefore , compared with other traffic systems, the maglev railway can reduce the journey time distinctly and its speed can padded the spacing among the vehicle, high-speed track railway and airplane. The maglev railway is not only speedy, but also quite safety. Owing to one another restriction between vehicle and track, vehicle is unable to deviate. Due to maglev railway adopts traving crane technique of non-contact, its comfort will be improved obviously.Speed target is the max running speed of trains, or the design speed of high-speed railway. The speed target of high-speed railway is the nubbin index of high-speed running, the outstanding indicate of high-speed railway system, the decisive parameter of the design of high-speed railway in the whole, and the aim to build the high-speed railway in the world. So the choice of speed target which must be advanced, feasible, reasonable in economics, and be propitious to the long-term's development. It also needs to consider that how to exertion the backbone effect of our railway in our traffic system.The choice of speed target can influence the design criterion about the lower part structures , the superstructures and the equipment about trains and stations, then it must influence the whole cost of the railway. So it is necessary to set down the speed target of maglev-railway for different conditions to ensure the high-speed maglev-railway developed in healthy, and to gain favorable economic effects and social benefits.Through using for reference main research methods of high-speed wheel railway lines about the speed target, and combine with the technical characters about the maglev railway system, this paper through using experimental of route selection to bring forward some advise about the high-speed maglev train's speed target aim at the different geographical conditions, the different topographical conditions, forming studying the relations between the speed target and building cost. Then put forward some advice about the speed target for high-speed maglev-railway system.
