The world's fastest maglev experimental platform was put on the line in Wuhan

On June 16, the "one-kilometer high-speed maglev test line" independently developed by Hubei Donghu Laboratory conducted its first public demonstration, and the test vehicle weighing 1030 kg successfully ran at a "top speed" of 650 kilometers per hour under the impetus of electromagnetic forceBreak the global record of similar platforms.

Walking into the "one-kilometer high-speed maglev test line", the one-kilometer-long maglev track is like a long dragon lying on the ground, and the scene is spectacular.

"It's ready, it's ready to test." There was a synchronization signal on the walkie-talkie, and Li Weichao pressed the start button. The test car at the south end of the track started with a roar, rushed to the north end of the track with lightning speed, and came to a steady stop after 10 seconds.

During the three tests, the all-media reporters of Hubei Daily experienced the on-the-spot at 100 meters, 300 meters and 600 meters of the track. Except for the 100-meter start, where you can barely see the trajectory of the test car, only a black shadow can be seen at the 300-meter and 600-meter mark. Even if you shoot with a professional DSLR camera, you can only capture the afterimage of the test car.

Background data shows that the test vehicle accelerated from zero to 650 kilometers per hour in just 7.1 seconds, a maximum acceleration of more than 8 Gs in the process, which is almost the limit of overload that fighter pilots can tolerate.

Why does the test car run so fast? Li Weichao introduced that under the action of electromagnetic force, the test car and the track produce the "same pole repulsion" effect, there is no physical contact between the two, the test car is suspended on the track, the vehicle is not restricted by friction during the acceleration process, only needs to break through the air resistance.

"650 kilometers per hour is not the ultimate goal of the test line, its typical working condition is 800 kilometers per hour, and it is expected that all construction tasks will be completed by the end of this year, and the acceptance conditions will be met." Li Weichao said that the high-speed maglev test line has high-precision speed control and high acceleration capabilities, and will become an open, cooperative and shared test platform after completion, which can carry out dynamic model tests, speed calibration tests and anti-overload tests in open atmospheric environments.

The purpose of the trials is to pave the way for innovative technologies to be applied in real life.

It is understood that high-speed maglev technology has application prospects in the fields of ultra-high-speed electromagnetic skid, high-speed maglev rail transit, low-altitude economy, aerospace electromagnetic launch, amusement facilities and other fields.

For example, the space shuttle can be "catapulted into the sky" through the electromagnetic system without turning on the engine when it is running and accelerating on the ground; When a commercial satellite is launched, the rocket does not have an ignition process on the ground, but launches the rocket into mid-air through electromagnetic acceleration and then turns on the engine; The jumping machine in the amusement park no longer uses hydraulic power, but is precisely controlled by an electromagnetic system to simulate the gravitational environment of the moon or even Mars, making the play experience richer......

The relevant person in charge of Hubei Donghu Laboratory said that the "one-kilometer high-speed maglev test line" is the epitome of Hubei Donghu Laboratory's transformation of scientific and technological achievements and new technology applications in the fields of new energy ships, rail transit, aerospace, new energy and intelligent microgrids.

Since its establishment more than 4 years ago, Hubei Donghu Laboratory has built 4 technology innovation centers, 3 scientific and technological achievement transformation companies and 10 pilot test platforms, and has obtained more than 50 patents authorized by the academician team, and has cooperated with Qingdao Metro, Hangzhou Metro, Hubei Port Group, China Huaneng Group and other units, with direct achievement transformation benefits of more than 400 million yuan, and economic benefits of more than 4.5 billion yuan for the whole society.
