Unlocking the Future of Transportation: China Leads the Charge in Hyperloop Development

The Principles Behind Hyperloop

  The concept of “Hyper High Speed ​​Rail” was first proposed by Elon Musk, the founder of the US Space Exploration Technology Corporation (SpaceX). down, driving at a very high speed. Magnetic levitation technology is a technology that uses the force of a magnetic field to suspend trains on the track, which can eliminate wheel-rail friction and reduce noise and energy consumption. A vacuum pipe is a device that sucks the air out of the pipe to form a vacuum state. This can reduce air resistance and improve the operating efficiency of the train. In addition, the super high-speed rail locomotive is a newly developed low-resistance locomotive with a streamlined duckbill shape, which can greatly reduce the air resistance generated during driving.
What are the advantages of hyperloop

  Fast super high-speed rail can reach more than 1,000 kilometers per hour, and can even exceed the speed of an airplane. This means that people can reach farther places in a shorter time, thus improving travel efficiency and convenience.
  High safety The design of the super high-speed rail is very safe, and it will not derail or roll over. The Hyperloop runs in a vacuum tube and is not affected by external factors such as weather and terrain, and will not collide with other vehicles. Due to the use of magnetic levitation technology, the train will not touch the track, and will not generate sparks, smoke and other safety hazards.
  The energy-saving and environment-friendly hyperloop reduces air resistance and friction, which can greatly reduce energy consumption and operating costs. It is driven by electricity, does not emit any harmful gas and waste, and has no pollution to the environment.
  Good Comfort The hyper-high-speed train runs smoothly, has low noise, small vibration, and low acceleration, which can bring passengers a comfortable riding experience. Passengers do not feel fatigued due to the short running time.
  Low operating costs Traditional high-speed rail wheels need to be returned to the factory for maintenance every 1.2 million kilometers, and must be scrapped every 2.4 million kilometers. However, the Hyperloop has no wheels and no friction loss, so after it is put into operation, the amount of maintenance is small, and the operating cost is significantly reduced.
What problems need to be overcome by super high-speed rail technology

  The vacuum tube technology and magnetic levitation technology required by the hyper-high-speed rail system have made some breakthrough research progress, but there are still many difficulties to be overcome. First of all, how to realize and maintain a large volume of low-vacuum space at low cost is a problem that needs to be solved. Secondly, how to build the platform so that it is convenient for passengers to get on and off the train, but also maintain the vacuum state of the pipeline. In addition, the super high-speed rail needs to adopt straight-line traction technology, but the efficacy of this technology cannot meet its power needs at present, and it still needs to be improved. Also, the current magnetic levitation technology is not stable enough for Hyperloop.

Countries around the world scramble to develop hyperloop

  At present, in addition to China, some countries are also developing and testing super high-speed rail technology, trying to seize the opportunity of this future transportation market. The most famous of these are Elon Musk’s SpaceX and Hyperloop One. SpaceX has built a 1.6-kilometer-long vacuum tube test site in Nevada, USA, to test various components and prototypes of the Hyperloop. Hyperloop One has established two super high-speed rail test lines in Nevada, USA and Dubai, UAE, which are 500 meters and 10 kilometers long respectively. In addition to the United States, countries such as Europe, India, Japan, and South Korea are also actively exploring super high-speed rail technology. India plans to build a 312-kilometer hyperloop line between Mumbai and Pune, which is expected to be completed by 2029. Japan and South Korea are also developing their own Hyperloop technology and have conducted several successful trials.

China Takes Lead in Hyperloop Development

  Chinese scientists have been researching superhigh-speed rail technology since 2017. The main research direction is the combination of supersonic flight technology and rail transit technology, that is, through the application of superconducting suspension technology and vacuum pipeline technology, supersonic near-Earth flight can be realized. This technology has been developed for 6 years, and it will not really usher in a major breakthrough until 2023. my country’s current super high-speed rail technology has realized operation in a low-vacuum environment, and the air resistance is 3% lower than that of traditional high-speed rail. Coupled with magnetic levitation technology, it has truly realized flying close to the ground. Compared with products made by the United States, Japan and other countries, my country’s maglev technology has more advantages in cost. Ordinary superconductors need to be cooled with liquid helium at a temperature of -269°C in order to maintain superconducting properties, while the “high temperature superconductor” developed in my country only needs to use liquid nitrogen at about -190°C to achieve the same effect. Since liquid helium is 50 times more expensive than liquid nitrogen, my country’s maglev trains greatly reduce manufacturing costs. In addition, our country also has the blessing of electromagnetic skids. On October 20, 2022, my country successfully operated the world’s first electromagnetic skid in Jinan, Shandong. Its maximum propulsion speed for objects over a ton can reach 1030 kilometers per hour, setting a world record for the world’s highest speed of large-mass ultra-high-speed electromagnetic propulsion technology . In addition to boosting acceleration, the electromagnetic skid can also reduce the pressure of the car body on the track through the upward electromagnetic force, so that the super high-speed rail can also reduce wear when accelerating.
