Maglev train - Chinese tourism scenic spots

Sea magnetic levitation train line west of Shanghai Metro Line 2 of the Longyang Road Station, east to Shanghai Pudong International Airport, maxicabs a total length of 29.863 km. Sino-German co-operation between the two countries by the developed world first magnetic levitation transportation line on March 1, 2001 in the Pudong dug under the first shovel, December 31, 2002 line test Bank, Jan 4, 2003 officially began commercial operations. Is the world's first commercial maglev line operation.


 

  This included the world's coolest train, with the front compartment of 27.196 meters long, 3.7 meters wide. Compartment in the middle of 24.768 meters long, 14 Within 10 minutes at Shanghai's Pudong Airport and back and forth between the fight. One place, you will experience the plane to "land aircraft" brought about by the strange feelings.
  Maglev trains - 21 century ideal means of transport. The maglev train principle is not difficult. It is a magnet for the use of "same-sex repulsion, the differences PHASE ", so that the magnet has the ability to resist gravity, that is," magnetic suspension. "


  Scientists will be "magnetic suspension" of this principle in the use of rail transport system, so completely out of the train tracks suspended and moving to become "round" train, up to several hundred kilometers per hour. This The so-called "maglev train", also known as the "magnetic cushion vehicles."
  From my 70s to start the development of the maglev train, the first principle like magnetically levitated small car in the spring of 1989, "floating" up. In May 1995, China's first manned maglev train over the tracks in the smooth running To come. This magnetic levitation magnetic levitation train conductor 3.36 meters, 3 meters wide, 2 m gauge can take 20 people, the design speed of 500 km.

  At present, as the fastest means of transport on the ground, the maglev train technology has indeed other ground transport technology unmatched advantages:
The first It overcomes the traditional round of the railway track to increase the speed of the main obstacles to the development of broad prospects. The first round of the railway track in the 1825, after 140 years, its operating speed before breaking 200 km /hour from 200 km /h to 300 km /h and spent nearly 30 years, although the technical And also improve the development and continue to improve the speed of the room has not, but very difficult. Should also be noted that the round of the railway track to increase the speed of the price is very high, 300 km /h high-speed railway construction cost of more than 200 km /h quasi-high-speed railway nearly twice as high, more than 120 km /hour general railway Three to eight times and continue to improve the speed of its cost will also rise sharply. Compared with the world's first magnetic levitation train is a small model in 1969 in Germany appears that Japan is in 1972 to create the. May be just 10 years after 1979, the maglev train technology to create a 517 km /h Speed record. At present, technology has matured, access to 500 km /h practical operation of the construction phase.



Second, high-speed magnetic levitation train, the maglev often lead up to 400-500 km /h, superconducting magnetic levitation up to 500-600 km /hr. For Yun, the speed of the main purpose of shortening the travel time for passengers, the speed with the requirements of the travel distance is closely related to the length. A variety of means of transport in accordance with its own speed, safety, comfort and economic characteristics in different travel distance play the role of the backbone. The experts on a variety of transportation With the total travel time and travel distance analysis showed that based on the total travel time, 300 km /h round of high-speed rail travel in the aircraft compared to less than 700 km away when superior. And 500 km /h high-speed magnetic levitation, the superior aircraft than the travel distance to reach more than 1,500 km Thirdly, low-power magnetic levitation train, according to the study of Japan and the actual results, with 500 km /per hour, per seat-kilometer maglev train the energy of the aircraft was only 1 /3. According to the German pilot, when TR maglev train reached 400 kilometers per hour, every seat kilometers to the With a speed of 300 km of high-speed wheel-rail train flat; and when the magnetic levitation train is also down to 300 km per hour, it's comparable energy consumption per seat-kilometer railway track low round of 33%.
