Hyperloop projects initiated in the USA may have failed, but this concept that Elon Musk put forward in 2013 Comes to life again in China. Moreover, the Chinese seem to have managed to control costs by making what western competitors could do.
Chinese engineers foreseen in the Hyperloop concept Low pressure magnetic levitation (manglev) system Last year, they built a 2 -kilometer test line in Shahanxi state. The tests that started in July give very successful results so far. Moreover, Chinese engineers It is said to reduce costs by 60 percent..
Different materials are used in the project in China than Musk’s suggested
CREC (China Railway Engineering Consulting Group) The team that works within the company uses a different design for low -pressure tubes than Musk’s suggested. Musk’s Hyperloop concept envisaged the use of large steel tubes. Engineers in China are closed with epoxy -coated reinforcement iron and corrugated steel expansion joints. It uses steel-concrete pipe design. This innovative design combines the stress strength of the steel and the pressure strength of the concrete, allowing the tubes to remain air -proof both in cold weather and in summer heat. Thus, energy loss is significantly reduced. But more importantly, the cost is remarkable to a significant extent.
The Chinese team not only changes the structure of the tubes, but also managed to eliminate another important problem with a new grilled system. The basis of the solutions lies in the use of low -carbon steel grids that reduce vortex currents encountered in magnetic levitation systems. This innovation will support travel close to supersonic speeds without the heat and pressure problems encountered in Musk’s projects. Ensures a durable and isolated corridor.
To build such a system The basic materials used need to be inventing from the beginning. Because traditional concrete coats can be deformed or cracking under the conditions close to the vacuum; Likewise, the standard concrete can be scattered when the inner air pressure approaches zero. In order to obtain a durable structure, Chinese engineers have activated special concrete mixtures reinforced with basalt fiber, glass fiber supplements that reduce fragility, and pre-vakum curing techniques.
Crec, who successfully built the 2 -kilometer test line, says that the road map is ready to enlarge this line. However, such a big A giant investment is required to implement the project. The fact that the US initiatives ended with frustration has caused suspicion of Hyperloop -like projects. However, the fact that Chinese engineers reduce the cost of 60 percent by using steel-concrete tubes instead of steel makes it more likely to have financially undergoing this project. We will wait and see if a large company will come into play to realize this project on a larger scale. However, we can say that China is much closer to the United States to make Musk’s Hyperloop dream come true.
