Description
Technical field
The utility model is related to normal conducting electromagnetic levitation traffic system railway technology fields, more particularly, to one kind for improving
The track structure of medium-and low-speed maglev train running speed.
Background technology
Normal conducting electromagnetic levitation (EMS) traffic system is low with running noises compared with conventional rails traffic system, energy of climbing
The outstanding features such as power is strong, turning radius is small, high safety and reliability, operation maintenance cost is low, terrain environment is adaptable.At present
Build up in the world and the medium-and low-speed maglev circuit for putting into commercial operation share four, be respectively Japan Nagoya the East Hillside Line,
The highest running speed of Incheon, South Korea airport line, Changsha airport cable release and Beijing S1 lines, train is 100km/h.With traditional ground
Iron train is compared, and speed advantage is not obvious, therefore the speed of service for improving medium-and low-speed maglev train becomes current middle low speed magnetic
The hot spot of floating traffic technique development.
The factor for influencing medium-and low-speed maglev highest running speed of train is mainly the linear motor driving capability of magnetic-levitation train.
Different from traditional wheel track vehicle, magnetic-levitation train generates suction using the levitating electromagnet of lower part with track makes vehicle suspension, simultaneously
The secondary induction plate interaction of linear electric motor primary winding and track on train pushes train to advance, so medium-and low-speed maglev
For the track of system as important functional component, the speed of service to improving medium-and low-speed maglev train has significant impact.
In view of this special track relationship of medium-and low-speed maglev system, if to improve the speed of service of magnetic-levitation train,
The length and width that existing train linear motor must be increased makes it under the conditions of the electricity of air gap unit area, magnetic loading are suitable,
The thrust of linear motor is improved, this requires track structures also to need to be correspondingly improved.
The track structure form that generally uses of medium-and low-speed maglev operation line is that a kind of collection is suspended, drawn and wheel function at present
The steel composite orbit of " three-in-one " is mainly made of F shaped steel rails, aluminium tablet and fastener etc., wherein F shaped steel rails and aluminium sense
Answer between plate that there are one layer of insulating materials.Medium-and low-speed maglev track can be divided into three parts according to its function, lower part F shaped steel rails
Inside and outside pole plate generation suspending power corresponding with the pole plate of U-shaped suspension magnet, top aluminium tablet are produced with linear motor interaction
Raw thrust, side plate, which connect with track sleeper beam and provided for vehicle, slides support.So compared with the track of wheel rail system, in it is low
The problems such as there are complicated, sectional dimensions for the floating track of fast magnetic greatly, processing and installation precision is high and project cost is high.
Utility model content
The purpose of this utility model is exactly to be provided a kind of for improving to overcome the problems of the above-mentioned prior art
The track structure of medium-and low-speed maglev train running speed.
The purpose of this utility model can be achieved through the following technical solutions：
One of the technical solution of the utility model is a kind of for improving the completely new of medium-and low-speed maglev train running speed
