Super High Speed ​​Rail has just completed major tests but also like the first step in the journey to Wanli

July 17 news, according to "Fortune" website reports, Los Angeles super high-speed rail technology startup Hyperloop One this week announced that it completed its first high-speed rail system's first "full-size" test, the company compared this to the Wright Brothers aircraft Take off for the first time.

(The English term is "Kitty Hawk moment." On December 17, 1903, the Wright brothers drove their first plane, "Flight 1", in North Carolina, USA. Kitty Hawke Beach, for the first time powered by continuous flight.)

In this test, the maximum speed of the train in the vacuum pipeline reached only 70 mph (about 113 km/h), which is one-tenth of the company’s final target speed. However, the company feels confident enough to start the next phase of testing later this year. They hope that the train can reach 250 miles per hour (400 kilometers) per hour. Ultimately, the system will reach a maximum speed of 750 miles (1200 kilometers) per hour, which is nearly the speed of sound.

Since Tesla CEO Elon Musk proposed the concept of "super high-speed rail" in 2012, its high-speed special effects have captured the public's imagination. However, many people who are developing this technology say that the concept of the “super high-speed rail” system is not just about speed, but it has changed our thinking about how people and goods are transported, and this industry can only be achieved in the United States. The 1.48 trillion US dollar scale.

Sherwin Pishevar, co-founder of Hyperloop One, said: “This impact is consistent with our founding vision of turning cities into subway stations, changing the meaning of people’s places of residence and workplaces, and helping to promote backward areas. Economic development."

Other companies, such as Hyperloop Transportation Technologies (HTT) and Arrivo, are also developing their own "super high-speed rail" technology.

Phillip Plotch, a professor of political science at the University of St. Peters in the United States, pointed out that in history, with the advent of new transportation technologies, there has been an abrupt change in human activity space.

Throughout the 19th and 20th centuries, changes in transportation, from carriages to elevated trains, have enabled the city to expand rapidly, meaning that people can live further from the workplace. Then came the automobile era.

Prochi said: "Everything has suddenly erupted, and now your place of residence (away from the workplace) can be 20 miles away, while the urban area can reach 1,000 square miles instead of a few square miles in the past, and the Hyperloop (super high-speed rail) ) It will make a difference again. You can live anywhere (hundreds or even thousands of miles away) from the workplace. For example, you can work in New York City and live in Virginia or Boston."

In fact, with companies such as Hyperloop One pushing people to sell almost supersonic travel speeds, the need to live near the workplace can be completely eliminated. At the speed promised by the engineers, taking a Hyperloop train from Los Angeles to San Francisco may only take 30 minutes (taking a car to take 6 hours). Several states, including Colorado and Texas, are studying the feasibility of this technology, paying close attention to its development and seeing if it is worth investing.

Proche pointed out that such a dramatic change will lead to major changes in the economy around the Hyperloop station.

He said: "It will be a country's most valuable real estate. Cities and communities without Hyperloop stations will lose in economic competition. All cities are competing for jobs, entertainment, tourists, etc. This is why every city is now All want to own the airport, train station and highway.

Other experts agreed.

Dane Egli, senior adviser to the U.S. Department of Energy, pointed out: “If you just look at high-speed railways in China or other parts of the world—wherever there are transportation hubs, they have economic dynamism and local economic development can be improved. Egley added that he and his personally-chaired non-profit organization "Hyperloop Advanced Research Partnership" called on President Trump to include the Hyperloop Development Fund in the president's own proposal. Trillion-dollar infrastructure plan.

Egley said: "We met with officials of the Congress, the House of Representatives Transportation and Infrastructure Committee, the Ministry of National Defense, the Department of Homeland Security and the Ministry of Transport. They were all excited, interested, and curious about the Hyperloop. Now I'm preparing (The White House) wrote a letter. We didn't report directly to Trump, but I hope to achieve this in the next three to six months. Then I didn't know if Musk would be with us. Langp reported)."

Musk is a member of the White House Business Council, which advises the president. But after Trump announced that the United States withdrew from the Paris Climate Agreement, Musk withdrew from the committee.

Although Egly and other advocates have no enthusiasm for Hyperloop, there are still many reasons to doubt Hyperloop. Many scientists and engineers have described this concept as unrealistic and costly. In addition, traveling in a Hyperloop capsule car, it is still unclear how it affects people's physiology. The new track will have to be laid. This is a huge logistical challenge and it is not easy to solve. Although the potential economic benefits for the city that is willing to accept this technology are obvious, some people still warn that this may not be a wise investment.

Prochid said: "Hyperloop technology startups are trying to attract investors. Many times, these things are just a selling point. They are making efforts to make people excited about the benefits of this technology. I think that in In the absence of a true understanding of this technology, all regions should not hesitate to try." (Liu Chun)

Single Notching

Stator and rotor laminations are an important part of motors and generators. For large-size and small-batch punching sheets, we usually use the notching method to produce them. The advantages of notching are that the cost of the notching die is low and the production cycle of the notching die is short. It is suitable for producing large size laminations, usually the outer diameter is from 500mm-1250mm. The slot size is more accurate than Laser Cutting.
