Dalian Qixiang Technology Co., Ltd. has successfully developed a new electromagnetic levitation high-speed rail technology after more than ten years of research and development. It is reported that this technology has increased the carrying capacity of the current magnetic levitation high-speed rail by more than two times. The load capacity of the high-speed magnetic levitation train has been increased from the original 20 tons to more than 50 tons. Realizing high-speed transportation with a large load capacity will double the transportation efficiency. Coincidentally, the company has also developed the super highway and magnetic levitation car technologies, which will increase the maximum speed of the highway to more than 200 kilometers per hour.
"To get rich, build roads first, and build highways quickly." Transportation plays a vital role in a country's economic development. In order to enhance transportation efficiency and enhance national comprehensive competitiveness, countries pay more and more attention to the development of rail transit and road transportation.
Each change of transportation means has significantly improved transportation technology. While increasing cost and cost, it also brings a significant improvement in transportation efficiency, and also allows the development of the national economy to enter a faster lane.
Recently, Dalian Qixiang Technology Co., Ltd. has developed a new electromagnetic levitation high-speed rail technology after more than ten years of research and development, and developed a 1:10-scale verification prototype in March this year. This new technology has doubled the load capacity of the current normally conductive electromagnetic levitation high-speed railway, realizing high-speed transportation with large loads for the first time, which can increase the load capacity of high-speed magnetic levitation trains from the current 20 tons to more than 50 tons, significantly improving the carrying capacity of high-speed magnetic levitation trains.
Large load electromagnetic levitation train verification test line
Magnetic levitation train Originated in Germany. As early as 1922, German engineer Hermann Kemper proposed the principle of electromagnetic levitation and then applied for a patent.
100 years later, Liu Zhongchen, a senior engineer of Dalian Qixiang Technology Co., Ltd., suddenly proposed a new structure of electromagnetic levitation train solution. The linear traction motor of German technology was changed from the bottom of the train to both sides of the train, "subverting" German technology by 90 degrees, realizing the original "disruptive" technological innovation from my country. The breakthrough change of this technical solution triggered a series of chain reactions. After freeing up space at the bottom of the train, an electromagnetic levitation structure solution with a larger load was discovered. The download weight was doubled while the track width remained unchanged, and the suspension power consumption did not increase. After several months of repeated optimization and technical research, Liu Zhongchen, general manager of Dalian Qixiang Technology Co., Ltd., developed a 1:10-ratio high-load electromagnetic levitation train verification line in March 2022, verifying that this new structural solution has greater load-bearing capacity and has the effect of energy-saving and power-saving.
This new electromagnetic levitation train adopts mature normally conductive electromagnetic levitation train technology, with the following characteristics:
1. Safety. Transportation safety is the first thing to consider. The train adopts a rail-mounted structure and will not break off the track, and can ensure safety at high speeds.
2. Large load capacity. The load capacity of magnetic levitation trains has increased from the current 20 tons to more than 40 tons, and can even reach a load capacity of 60 tons, which can realize high-speed transportation of heavy-duty trucks. The current China-Europe freight train adopts the wheel rail train heavy-load freight method. The weight of the 40-foot small cabinet container weighs 23-25 tons, and the weight of the 80-foot large cabinet container weighs 50 tons. Such a large load capacity cannot be achieved by current magnetic levitation train technology. It can only use heavy-load wheel rail freight trains, and cannot operate at a speed of 120 kilometers per hour, otherwise it will exceed the life limit of the bearing and cause risks. The China-Europe freight trains vary according to the starting and ending routes, and the train transport time is about 12-21 days. After the magnetic levitation train has a large load capacity of more than 50 tons, it can enable the heavy-load transportation to reach a speed of 600 kilometers per hour, the transportation time can be shortened to 3-4 days, and the transportation efficiency can be increased by 5 times. The improvement of load capacity allows passenger trains to be made into double-decker trains, transporting more passengers each time, reducing transportation costs by nearly 50%. Moreover, in the later stage, the development space will be improved to a speed of more than 1,000 kilometers per hour.
3. Strong climbing ability. The linear motors on both sides of the train can increase traction force from each other and continue to maintain excellent guidance capabilities, so that the heavy-load climbing capacity can be increased from the original 100 ‰ to 200 ‰, and can climb over hilly areas or steep slopes without having to drill a tunnel. The improvement of traction capacity can shorten the station spacing to increase the passenger rate, and the improvement of braking capacity can shorten the brake deceleration distance.
4. Energy-saving and power-saving. With the same load capacity, 40-50% savings than German electromagnetic levitation trains. The volume of cargo carried per cargo has been increased and transportation costs have been reduced by nearly 50%.
5. It can realize the mixed transportation of passengers and freights. It turns out that wheel-rail high-speed rail is supported by wheel rails. Due to the bearing fatigue limit, the speed cannot be fast under heavy loads and the load cannot be large at high speeds, which makes the load capacity of the current high-speed rail at 350 kilometers per hour cannot exceed 15 tons, and can only be transported by passengers or light loads. Heavy-load freight trains can only pull cargo at a slow speed, otherwise it will cause risks after exceeding the life limit of the bearing. Heavy-load trucks cannot be mixed with high-speed passenger and high-speed rail lines, and passenger and freight need to build separate dedicated lines. For example, coal transportation must be built with separate transportation lines, and it takes 7 days to transport from coal production to thermal power plants. Large warehouse reserves must be built. If a large-load magnetic levitation train is used, it can only be reached in one day, and the remaining carrying capacity can provide passenger and other cargo transportation. After the load-load capacity of magnetic levitation trains is greatly improved, high-speed mixed running between light-loaded passenger cars and heavy-load trucks under high speed can be achieved. The transportation volume of one line is about 4 times that of the current high-speed rail traffic, which will greatly improve the transportation efficiency of my country's high-speed rail lines.
The obvious problem restricting the popularity of magnetic levitation high-speed rail is that the cost remains high. This new high-load magnetic levitation high-speed rail track structure is simpler than German magnetic levitation technology, which will reduce the cost of magnetic levitation high-speed rail to a closer approach to the current high-speed rail line cost, about 10-30% higher than the current high-speed rail cost. The more complex the road conditions, the smaller the cost difference. This new technology provides technical support for my country's high-speed railways to achieve high-speed, large-volume passenger and freight mixed transportation, and achieve efficient logistics transportation, and will provide infrastructure guarantee for the rapid development of my country's economy.
This technology completely subverts the German high-speed magnetic levitation train technology, which will allow my country's high-speed magnetic levitation train to surpass the German magnetic levitation train technology, which has always been a benchmark in terms of technical principles, and change China's impression that it will only imitate foreign technology, which will allow the world to re-understand China's innovative development potential and contribute to China's technical solutions with more international competitive advantages.
Although this electromagnetic levitation train has no upper limit in its theoretical speed, considering the economy and safety of actual construction, the speed can reach 600 kilometers per hour under standard atmospheric pressure. In the future, combined with vacuum pipeline technology, it can overcome more than 90% of the air resistance, and the speed can reach 1,000 kilometers per hour, achieving ground pipeline flights against the ground in an altitude environment of tens of thousands of meters. The high-speed rail that travels thousands of miles a day will cause earth-shaking changes in people's travel efficiency, and the concept of time and space distance will also change. You can imagine the following scenario:
You can take a flying iron to a scenic spot thousands of kilometers away on weekends, and you can rush home that night. Long-distance travel has become more fashionable, and the time to ride ineffectively is shortened, and you can go to a further place in your life. The express delivery industry will also choose this kind of flying iron more. The delivery will arrive in the morning and the afternoon, and northerners can eat fresh fruits shipped from the south on the same day. Products from manufacturers from all over the country can be received on the same day or the next day, and sales have been greatly increased. Supporting factories can choose at will across the country, and the country is like a city... The same-city effect appears.
In the field of road transportation, Dalian Qixiang Technology Co., Ltd. applied the super high-speed rail technology to cars in 2017 and developed the magnetic levitation vehicle technology, which can transform the expressway and make the maximum speed of the magnetic levitation vehicle exceed 200 kilometers per hour.
This new magnetic levitation car uses the array permanent magnet at the bottom of the vehicle and the conductive metal on the highway to generate electric suspension and automatic guidance at high speed without deviating from the track, which can realize automatic driving. The power supply on the highway can power the linear motor of the track. The car no longer burns oil and consumes electricity. Wherever the track is built, the magnetic levitation car can "fly" wherever it is built, which will prevent future new energy vehicles from worrying about the driving range of cars on the highway.
This super highway can carry the transportation of goods between major cities, allowing magnetic levitation cars to switch from burning oil to using electricity, making new energy vehicles more environmentally friendly emissions, and helping China's carbon neutrality goal to achieve the goal of logistics transportation between cities in my country faster, allowing online shopping products to reach users faster, and speed up the circulation of products . Autopilot on such a super highway can take a break while flying on the ground.
