Description
Technical Field
The invention relates to the technical field of rail vehicles, in particular to a rail traffic device.
Background
The existing rail transit workers have common trains, wheel-rail high-speed rails, magnetic suspension high-speed rails and the like, and in order to further improve the speed, the magnetic suspension super high-speed rails of the vacuum tunnel are currently researched and developed, and the aim is to realize high-speed operation of more than 350 km/h. The common train provides power through an electric power or a steam engine and moves forwards through the rotation of wheels, so that the speed is low and the efficiency is low; the high-speed rail of the wheel track is powered by electric power and still moves forwards through the rapid rotation of the wheels, the speed is high, the current practical application is up to 350km/h, and the space for further improving the speed is small due to the restriction of the rotating speed of the wheels and the adverse factors of contact friction with the track; the magnetic suspension high-speed rail realizes suspension and magnetic drive by providing a magnetic field through electric power, has high speed, is put into practical use at present up to 350km/h, has higher construction cost than the high-speed rail of a wheel rail, also has air resistance, and has great cost for further improving the speed.
In the current research and development of vacuum tunnel magnetic suspension super high-speed rail, the air resistance is reduced through a vacuum tunnel and magnetic suspension, the speed can reach more than 350km/h through magnetic drive, but the current research and development is still in an initial stage due to the technical difficulty and cost factors of vacuum tunnel construction and high-temperature superconduction, and the practical application is far away.
The principle of the air suspension train is that compressed air is sprayed onto a rail by using an aircraft engine with very strong power, so that an air cushion with the thickness of several millimeters is formed between the train bottom and the rail, and the whole train is supported and suspended on the rail surface. Then the rear propeller engine is used for propelling the train to advance. Such trains are commonly referred to as "air-borne trains". It is also called an "air cushion train" because it is supported as if it were by air cushions. France is the world's earliest country in which air-cushion trains were built. In the 60's of the 20 th century, two air suspension railways, one 18 km long and the other 6.7 km long, were built in paris and the suburbs of orleans, and multiple running tests were conducted. The test speed of the train was 200 to 422 km per hour. The air cushion vehicle used in the suburb of Orleans in 1969 is 26 meters long, 3.2 meters wide, 4.35 meters high, and 20 tons heavy, and can be used for 3 people. In 1955, Yiandei manufactured two LWT-12 air cushion trains, which were purchased by rail companies such as the United Pacific, but could not be made available. However, as to how to design the air-levitation train and the corresponding track, so that the air-levitation effect of the train is better, there is no report of related technical literature in the prior art.
Because the most advanced vacuum tunnel magnetic suspension super high-speed rail at present relates to the technical difficulties, cost, potential safety hazard and magnetic field environmental protection problems of realization of high-temperature superconductivity and vacuum tunnels, a novel gas suspension high-speed rail transit device which can run under normal ground atmospheric conditions, does not need a vacuum tunnel, does not need magnetic suspension, has low construction and operation and maintenance costs, safe and reliable running, is easy to realize in technology, efficient, energy-saving and environment-friendly and has the speed of more than 350km/h is urgently expected.
