With the development of the Internet in recent years, we can often see from the media or news that there is a group of people who firmly stand their ground and face the temptation of tens of millions of wealth. But he remained unmoved and firmly chose to stand on the side of the motherland, and used practical actions to prove his determination and ideals for the motherland. They gave up their own interests and contributed to the construction and development of the motherland. What we are going to talk about today is also related to this. A Chinese girl invented a maglev car. A foreign company wanted to buy it for 50 million, but she said she would give it to the motherland.
The girl's name is Cai Yuchen, a post-90s generation from Shanghai. In 2017, Cai Yuchen designed a maglev car called "Floating Boat", which was held in the future module of foreign countries. He became famous at the Automobile Design Conference and shocked the Chinese and foreign automobile manufacturing industries. Just from the appearance, this maglev car has a fashionable and futuristic feel. It has no tires and can rotate. It also has the function of driverless driving. Its simple appearance, translucent body and smooth lines have attracted countless people. Favorite automobile manufacturing industry. The working principle of this maglev car is very simple. It uses electromagnetic force to achieve contactless levitation between the car and the track.
Automakers from various countries are very surprised by this car, and a German automaker is even more optimistic about its development prospects, because it not only has a sci-fi design appearance and advanced intelligent technology systems, Coupled with the environmental protection concept of green and energy-saving travel, it is enough to seize the market in the near future. Immediately after the conference, anxious German automobile companies contacted Cai Yuchen and expressed their willingness to invest US$50 million to acquire her future design. But Cai Yuchen was unmoved and immediately rejected the German request. Afterwards, Cai Yuchen said that she was Chinese, so there was no doubt that she would dedicate all her lifelong learning, technology and design drawings to her motherland. This is also Every Chinese can do it, and this maglev car technology only belongs to China.
However, from a technical perspective alone, in order to realize the true magnetic levitation car technology and apply it to real life, several technical problems still need to be overcome, because the principle of levitation cars is based on magnetic levitation, so It is necessary to use the strong repulsion of two magnetic fields to achieve the levitation of the car. It is impossible to rely solely on the tiny magnetic force and the earth's magnetic field with chaotic directions. Therefore, in order to achieve this, special strong magnetic roads must be designed. , the attraction and pull formed by the metal objects around the strong magnetic road surface and the magnetic road surface has become a problem that needs to be solved.
Secondly, a car with a magnetic levitation power source not only provides a steady stream of current to the magnets on the chassis to form a strong magnetic field, but the magnetic field also propels the car forward, and this energy It is also necessary for the car to be able to continuously supply energy when it is at a standstill, so that the car body can always be suspended above the strong magnetic circuit. To achieve this, the car must be equipped with a small but powerful battery or energy as a power source. This naked problem requires technical research to achieve.
It is worth mentioning that in the young man Cai Yuchen, we can see that contemporary college students and young people are bravely shouldering the hope and future of the motherland with their youthful wisdom and talent. We need more People like Cai Yuchen who contribute to the future development of the motherland, as Liang Qichao said, when young people are strong, China will be strong.
