China's High Speed Targets 1000 Per Hour | Maglev
The economy is growing very fast in China, which is growing every passing trains very seriously. Upgrading the network to 2020 and increasing the speed to 1000
One of the alternative technologies in the world, especially with environmental pollution, is electricity. Every year more and more companies produce and market electric or hybrid models. However, there are problems that cannot be solved by electricity in the automobile industry. For example, traffic and speed limits. Therefore, developing countries are turning to a non-traffic-driven rail system that can quickly cover long distances.
France and Germany in Europe, Japan and China in the Far East rail system is very stable. While France is heading for standard wheeled TGV trains, Germans have been investing in magnetic trains for a long time. China is the biggest customer of these trains.
2 manyetik Maglev lev, one of the world's most commercially active railway lines, is located in China. Moreover, this system in China is the longest Maglev line and one of the fastest train lines. This line, which connects Shanghai Pudong Airport in Pudong City Center, is called ong SMT ı, namely, Shangai Maglev Train.
Launched in 2001, this line was completed in 2004 and was put into service for passengers. In other words, magnetic trains have been in China for 8 years and now plans to expand this line of 30 kilometers. The goal of the Chinese government is to take much longer and much faster service to the Maglev's service in 2020.
Maglev technology takes its name from “Magnetic Levitation Mag. This term, which refers to magnetic ascension, clearly explains the system of the train's operation: these trains really go in the air, and after the take-off, they never come into contact with the rails during the journey. Therefore, since it has no friction, it can go to much higher speeds and also consumes less energy.
The foundation of Maglev technology is based on 1930s. The patents received in those years later were evident in the construction of the first Maglevs in the 1960. Although he did not invest in this technology, he set up a Maglev line in the USA, New York in 1968. But it was the Germans who provided the real development of technology. 70'li and 80'li years producing many different Maglev technology and speed records, the Germans now also have the most experienced companies in this regard.
In the lower part of the train there is an overhang to the bottom of the rails. The magnets in this protrusion pull the magnets on the rail and keep the train in balance. In order for the train to take action, the logic of opposing poles is used. Coils on the bottom and bottom of the train are loaded on a regular basis + and - so that the pole in the train has to follow the magnetic field in the continuous rail. The train is moving. In this system, speed control of the train is done by frequency control. The rate of change of the plus and minus poles determines the speed of the train.
Maglev 's most serious application to the public was introduced in China. The 2004 has been active since 430 and the 30 mileage is at the 7 20 501 in minutes. In fact, the train has a record speed of 400 miles per hour. But due to the environmental conditions and the comfort of the passengers, the average speed is kept at around XNUMX kilometers per hour.
There are Germans behind the Maglev in China. System outlines and trains prepared by the company named Transrapid. This company was founded in partnership with Siemens and ThyssenKrupp. The rail system was built by a group of Chinese companies.
The cost of the SMT system to China was 1.33 billion dollars. The cost of building one kilometer of the bi-directional system is 43 million dollars. Including the cost of trains. Therefore it is very costly to install the Maglev system. The reason for this cost is that the entire rail system is equipped with millions of expensive coils. In addition to this, it is necessary to have a straight line in order to keep trains at high speed. That means a lot of bridges and a well calculated slope.
But China has no intention of stopping. The Chinese government, which has plans since 2006 to expand the system, wants to increase speed on the one hand. Nowadays, the 1000 is using the speed of the trains. Obviously, it is quite difficult to achieve this with the standard method, because air friction and the G force effect on the passengers will reach tremendous levels. Therefore, trains are planned to travel in a vacuum tube.
France standard wheeled TGV trains can reach speeds of up to 500 km. But this technology is more limited than Maglev. As a result, the wheels have a physical limit to the rails. Maglev technology is theoretically unlimited in speed. Outside China, Japan uses Maglev trains, while South Korea plans to launch a new line in a short time. In addition, countries like Malaysia, India, Iran and Venezuela are making plans for Maglev. In Turkey is similar to the TGV high-speed train system is installed and the system does not come at all costs because Maglev agenda.
