Enjoying the scenery by car is a popular way for many people to travel leisurely, have you ever experienced the scenery on the maglev train? While enjoying the scenery, you can also feel the charm of the maglev traffic "floating" tour and integrate with the scenic spot, does this really realize the flow of people in the picture?
Today, the first domestic maglev tourist line, Guangdong Qingyuan Maglev Tourist Line, was launched for the first time and entered the stage of joint debugging and testing. The total length of the line is 38 kilometers and will be built in two phases. The first phase is 8 kilometers long and is expected to be officially opened at the end of this year, when it will realize the rapid access between Guangqing Intercity Yinzhan Station and Chimelong Theme Park. After the completion of the entire project, it is expected that the average daily passenger traffic will reach 1,31 passengers in the initial period and 9,14 passengers in the long term.
So, what is a maglev train? What does it float on? Is it safe? Do maglev trains have magnetic radiation? Is the ticket price expensive?
What is a Maglev Train? How is the ride different?
What is a Maglev Train? How does its ride compare to riding in a regular car?
According to reports, maglev train is an emerging means of transportation that realizes contactless suspension and guidance between the train and the track through electromagnetic force, and then uses linear motors to generate traction operation.
Since maglev trains can achieve contactless operation with tracks and lower noise than ordinary trains, the stability of the train operation is better and the comfort of passengers is greatly improved.
Maglev trains can be divided into several types according to speed, such as medium and low-speed maglev, high-speed maglev and ultra-high-speed maglev. The maximum operating speed of medium and low-speed maglev trains can reach 140~160 kilometers per hour, the maximum operating speed of high-speed maglev trains can reach 400~600 kilometers per hour, and the maximum operating speed of ultra-high-speed maglev trains can reach more than 1000 kilometers per hour.
How does a maglev train "float"? How is security ensured?
How does a maglev train "float"? How is security ensured? At present, what are the new technologies of China's emerging rail transit dominated by maglev?
Maglev is a system of rail transit, such as maglev technology, which ensures that the vehicle can be stably "suspended" and stabilized "guided".
Qian Qingquan, academician of the Chinese Academy of Engineering: The maglev train relies on the action of electromagnetism, that is, the magnetic force, and we can use this force to suck and repel this force to be able to lift the car up.
Therefore, a large number of electromagnetic control technology and electromagnetic materials will be used, maglev trains need high-power conversion systems, control systems and strong coupling, when the train is running, there is no contact between the car and the ground, so high sensitivity, low delay communication technology and lightweight new materials are required.
Yu Qingsong: Maglev trains have many key system technologies, and these key supporting technologies of maglev will drive a large number of emerging technologies and emerging enterprises in our country in electromagnetic materials, superconducting materials, including new lightweight materials, control, communication, transmission technology, etc.
According to experts, Southwest Jiaotong University, National University of Defense Technology, Tongji University and other universities have mastered the key maglev control technology, F rail, rail row, turnout and other key equipment processing and manufacturing have been localized, the current localization rate of medium and low speed maglev transportation system exceeds 90%, has completely independent intellectual property rights, and has a solid foundation for becoming a national strategic and innovative emerging industry.
As a kind of emerging rail transit, what are the advantages of maglev transportation?
Qian Qingquan, an academician of the Chinese Academy of Engineering, said in an interview with reporters from the main station that the safety of medium and low-speed maglev trains exceeds that of other rail transit modes and is absolutely safe. Maglev belongs to emerging rail transit, and the completion of Qingyuan Maglev Tourism Line is also another exploration and attempt in emerging rail transit in China.
Traditional rail transit has state-owned large railways and urban subways, emerging rail transit has special track structure, traction walking and guidance mode, or vehicle structure is different from the characteristics of traditional standard railways and conventional trains, is with the progress of science and technology and rises, to adapt to the social and economic green, low-carbon, environmental protection, beautiful development needs. According to experts, the emerging rail transit modes currently studied mainly include medium and low-speed maglev, high-speed magnetic levitation, straddle monorail, as well as empty rail, light rail, magnetic rail and so on.
What are the advantages of maglev transportation in terms of speed and environmental protection?
In terms of application scenarios, high-speed maglev can meet our demand for higher speed transportation on land, fill the speed gap between aircraft and high-speed rail, and meet the differentiated travel needs of different groups of people. Medium and low-speed maglev can effectively promote urban space optimization and the construction of metropolitan areas and urban agglomerations, and promote regional coordinated development.
Qian Qingquan, academician of the Chinese Academy of Engineering: medium and low speed maglev, the first advantage is that its climbing ability reaches 7%, and the turning radius is small, it is only 70 meters, so the advantage is that the line selection is simple; The second is that it has no noise, no vibration, no friction after suspension, no dust, and is also environmentally friendly; The third operation is rail running, holding rail does not derail, safety is relatively high, and its maintenance is particularly simple.
Medium and low-speed maglev is equipped with an evacuation platform next to the track, and passengers can use the evacuation platform for evacuation and rescue in emergency situations such as fire. The maglev train has no mechanical contact with the track during operation, and can adapt to extreme low temperature weather of minus 40 °C under normal circumstances, and has good adaptability to bad weather such as rain, snow, and freezing.
Does the medium and low speed maglev have magnetic radiation?
Medium and low speed maglev noise is low, turning radius is small, can be shuttled in the city, see this, many viewers may worry, will the electromagnetic generated by the maglev vehicle have radiation to the human body?
Qian Qingquan, academician of the Chinese Academy of Engineering: Actually, because it is all closed, the magnetic field is closed, it will not diffuse, and the problem of magnetic radiation is about 10 meters away, which is the same as other traffic, and has no effect. Within 2 meters is like a fluorescent lamp, 2 meters away from us, and far below the national standard for the impact of electromagnetic radiation on the human body.
The noise value generated by medium and low-speed maglev is about 63 decibels, which is significantly lower than other urban rail systems; Since there is no wheel-rail wear, no iron powder or rubber dust is generated during operation, and environmental pollution is avoided to the greatest extent. There will be no noise, vibration and radiation effects on the inhabitants along the route.
Is the cost of the maglev train high? Is the ticket price expensive?
Transportation infrastructure is often expensive to invest and take a long time to recover costs. So is the cost of medium and low-speed maglev high? Are the fares affordable?
Medium and low-speed maglev traffic has the characteristics of strong climbing ability, maximum slope up to 70 thousandths, small turning radius, and a minimum radius of up to <> meters, making it particularly suitable for shuttling in the city.
Xie Hailin, General Manager of China Railway Maglev Transportation Investment and Construction Co., Ltd.: Compared with the subway, the capacity of emerging rail transit is lower, but its investment cost is much lower, which is very suitable for some non-megacities or non-first-tier cities, and its operating costs are also very low.
In addition, in terms of fares, if the medium and low-speed maglev line belongs to an urban rail transit line, the fare is not subject to its construction cost limit, and is determined by the local operation department according to the needs of social and economic development, just like the traditional urban rail transit fare and ticket system.
What is the development prospect of medium and low-speed maglev transportation in China?
Industry insiders said that medium and low speed maglev is a representative of emerging rail transit mode, medium and low speed maglev transportation design speed can reach 160 kilometers per hour, comparable to the traditional urban (suburban) railway, can be used as a suburban line in the city, strengthen the connection between the central urban area of the city and the peripheral groups and peripheral groups, and have more prominent advantages in terrain adaptability, green environmental protection, safety and other aspects.
Up to now, there are three medium and low-speed maglev transportation lines in operation, including Changsha Airport Maglev Express, Beijing Maglev S1 Line, and Phoenix Maglev Tourism Line, and many more lines will start construction.
In terms of high-speed maglev transportation, Shanghai has the only high-speed maglev demonstration line in operation in the world. In the future, whether traveling or traveling, more passengers will have the opportunity to experience maglev transportation - the unique charm of this emerging rail transit.
