In the light of the sun, a “high-faced” train “floating” at about 8 mm above orbit, from the long sandy south station, crossing residential areas, factories, bridges, villages ... Fly forward and arrive at the long sand yellow flower airport after 19 minutes and 30 seconds。
On 6 may, the long sand magnetic flow line was officially operated as a passenger test. This is the first medium- and low-speed commercial railway operation in the country with full autonomous intellectual property rights, marking the achievement of full coverage of our magnetic float technology, from research and development to its application, as the world's few countries with that technology。
The long sand magnetic fast line, which is 18. 55 kilometres long, links the long sand train south station and the long sandy yellow flower airport. The train runs for 19 minutes and 30 seconds with a maximum passenger capacity of 363 and a one-way fare of $20。
In order to facilitate passengers, the magnetic float train also provides free wifi and is expected to install a “city terminal” at the magneto-high iron station after august of this year to allow passengers to pre-load on-board machines, baggage, etc。
The long sand magnetic flow line is a major autonomous innovation for the engineering and industrialization of magnetic float technology in the country, bringing together scientists。
Construction began in may 2014. In the face of the foreign monopoly of technology, the parties concerned, with their own innovative purpose, have managed to overcome their difficulties by developing and producing a fully intellectually-owned magnetic float “wind chaser”, designed at a maximum speed of 100 km per hour。
According to the relevant technicians, the medium- and low-speed magnetic flotilla train was suspended and directed using the attraction between the on-board electromagnet and the orbital steel tracks, and its vehicle hanger was designed to be rounded, with the lower end of the car stretching out two curved arms. Once the train is electrified, a magnetic field is created between the vehicle-mounted electromagnet and the steel tracks. At that point, two rows of arms would hold the tracks tight and the vehicles would be suspended。
The magnetic float train, which supports the body entirely by suspension, is a technical challenge in order to maintain a steady and fast advance in its operation. To this end, scientists have developed a gap sensor that can ensure constant suspension of magnetic vehicles. Four sets of sensors per hanger detect the balance at a frequency of 10,000 per second, depending on the operation of the train. If there is a point-by-point imbalance, the system adjusts to the specific circumstances to achieve a balance, so as to eliminate the risk of the vehicles being operating in an uneven state of operation and enhance the safety of the vehicle。
“a floating system with autonomous intellectual property rights, a hanger adapted to the 1860 mm track, a highly reliable whole-car electrical system ... Our medium- and low-speed magnetic suspension train technology has reached world-class levels.” liu yumei, a chinese engineer, said。
Industry believes that medium- and low-speed magnetic float railways have the advantage of low noise, investment, adaptation and low land availability over other orbital vehicles, providing greener, environmentally friendly transport solutions to alleviate the growing “large-city disease”。
