Abstract
A low-cost ultrahigh-speed magnetic hovertrain structurally features that a new railway bed is paved on the basis of existing one, the concrete seats and reverse L-shaped sections are sequentially arranged on new bed, Al-alloy frame is fixed to existing rail, several transverse beams are fixed to the bottom of existing train carriage, two longitudinal beams at both sides of train carriage are used to link said transverse beams, two electromagnets are symmetrically fixed to left and right of longitudinal beams in intervals, two laser distance meters are fixed between two electromagnets in one pair, and a limit frame and an Al-alloy frame are fixed to bottom of train carriage. Its speed can reach 500 Km/N with low cost.
Description
The present invention relates to magnetic suspension train.
Present magnetic suspension train is to utilize buoyancy or the attractive force that the powerful electromagnetic field of superconductor produces under the low temperature to realize not having the friction high-speed cruising, and the magnetic suspension train speed per hour that adopts the superconduction synchronous linear motor to drive as Japan can reach 500km/h; Former West Germany also disclosed similarly trial sheet.Because the generation of the lift force of these superconductors is by liquid helium, liquid nitrogen or fefrigerator in the railway carriage superconducting magnet in the railway carriage to be cooled to extremely low temperature could produce, no matter train rail is to be made of conventional magnet or superconducting magnet, its cost is all extremely expensive, thereby above-mentioned magnetic suspension train can't be dropped into practical application.
Task of the present invention is: overcome the deficiencies in the prior art, existing railway and car body are improved, design a kind of with low costly, adopt magnetic levitation technology to obtain not have the magnetic suspension train of friction high-speed cruising.
Task of the present invention realizes as follows: the rail of low-cost superhigh-speed magnetic hovertrain is to lay new roadbed on the basis of existing roadbed and sleeper, fixing concrete base on new roadbed, on concrete bed, fix inverted " L " shaped steel, and fix an aluminum alloy frame on the top of original " worker " word iron and steel rail, this frame width equates with the interior distance of two rails, length prolongs with railway length, magnetic suspension train is to lay several crossbeams in the bottom of original car body, crossbeam is coupled together with two longerons in the car body both sides, the top of longeron and a left side, two electromagnet are fixed every certain interval in the right side, one is vertical electromagnet, one is transverse electric magnet, between every pair of electromagnet, fix two laser rangefinders, fix a framing mask in the car body bottom, when train was unloaded, electromagnet was not switched on, wheel contacts with rail, the height of framing mask equates that with the height of damper spring when the electromagnet energising picked up car body, wheel could leave rail together along with car body; Vertically the gap between electromagnet and " L " shaped steel remains on when not switching on about 10mm, remains on about 5mm when electromagnet is switched on, and the gap between transverse electric magnet and " L " shaped steel remains at about 5mm; Fix an aluminum alloy frame in the bottom of former car body, its width is slightly less than interior wheelspan, length equates with length over ends of body, the base of framework is from the very little distance of aluminum alloy frame on iron and steel rail top, be equipped with lead in the aluminum alloy frame of car body bottom, when car body is sucked from track, feed three plase alternating current in the lead, this alternating current generates eddy current (with the opposite electromagnetic field of direction in the aluminum alloy frame of car body bottom) at the aluminum alloy frame internal induction on iron and steel rail top and promotes car body and advance at utmost speed; The electric power that train needs is provided by transmission of electricity bare wire and lead-in wire, and vertically the size of current in electromagnet and the transverse electric magnet guarantees that by laser rangefinder and the common control of computing machine vertical electromagnet and " L " shaped steel, transverse electric magnet remain at about 5mm with the gap of " L " shaped steel.
The present invention realizes energy-efficient purpose owing to existing common railway and train are become do not have to rub its running velocity of superexpress train of running at high speed can reach 500KM/W with lower cost.
