Science And Technology Help Sochi Winter Olympic Games

Less than one year ahead of schedule, the snow skiing was built, and the snow was not created by snow. It was designed as a research aircraft, using carbon nanotubes to "a href=" http://www.91se91.com/news/index_f.asp "> equipment" /a > Snowboard... "P

Below P, the twenty-second Winter Olympic Games are going on in Sochi, Russia. Athletes from all over the world are fighting for honor and achievement.

While marveling at the athletes' individual talents, people are also amazed at the new technology emerging inside and outside the stadium.

Recently, a number of experts interviewed and analyzed the technology in the field.

When the opening ceremony of the Sochi Winter Olympic Games was held at P, it happened to be "warm winter".

Although other parts of Russia have already entered the cold winter, the temperature in Sochi is still high, maintaining above 10 degrees Celsius.

How can we compete in snowboarding without snow? < /p >

At P, we need technology to help us.

The Winter Olympic Games was equipped with 450 snow making machines and made preparations for "not relying on one centimeter of natural snowfall".

What is worth mentioning is that a high-tech artificial snow making system purchased by the organizing committee from Finland can regulate snow production according to real-time temperature, and even create snow at temperatures of 20 degrees Celsius.

< /p >

< p > why is the snow making system so magical in Finland? For this reason, Pu Mingrui, a journalist and Cultural Counselor of the Finland Embassy in China, told reporters that this is related to the geographical location of Finland and the long-term accumulation of snow treatment techniques.

< /p >

< p > Pu Ming Rui also said: "although there is no heavy snow in Sochi, Finnish Michael Maledikainen has used insulation technology to help Sochi collect and store 800 thousand cubic meters of snow ahead of schedule."

< /p >

< p > as early as last winter, according to Mahler Di Canin's "snow guarantee" plan, 14 huge reflective blankets, like a large quilt, were covered in the snow on the shady places of the mountains, blocking the sunlight.

Once necessary, the snow can be pported to the ski areas at the bottom of the mountain immediately.

< /p >

< p > after 1 years, although some snowfalls are melting, there is still about 500 thousand cubic meters of residual snow, which is equivalent to the more than 450 meter high square column.

It is said that only the current storage of snow is enough for the end of the Paralympic Games.

This winter Olympic Games, P andmar, from the United States, cooperated with the space giant Lockheed Martin, using motion capture and aerospace engineering technology to create better skaters for American skaters.

< /p >

< p > the R & D team used high speed cameras to capture the ice movement of speed skaters. According to the collected data, the glass fiber mannequin was made. Then the team wore hundreds of different a target= "_blank" href= "http://www.91se91.com/" > clothing "/a" to the human body model. After hundreds of hours of wind tunnel testing, we found the best material for making clothes.

Since then, they have created a computational fluid dynamics model to analyze the airflow around certain skaters in some body parts, use different materials in the thigh, reduce drag, change the position of the zipper, and increase small bumps.

Finally, a high-tech suit was completed.

< /p >

Cao Chunxiao, academician of the Chinese Academy of Sciences and aviation material expert, told reporters that, like designing a plane to consider reducing drag, reducing fuel consumption and increasing speed, the match clothing is raised to make it change with streamline and make it more accord with aerodynamics.

< p > Xi Yubao, vice president of Physical Education Institute of Anhwei Normal University, also pointed out that the technology content of sports a target= "_blank" href= "http://www.91se91.com/" > shoes < /a > clothing has great influence on the performance of competitive sports.

However, "in the development of competitive sports apparel such as skating clothing and other high technology, the domestic ability is relatively weak, and there is a certain gap with foreign countries".

< p > < strong > nano technology helps alpine skiing < /strong > /p >

At P, nanotechnology also played an important role in the Winter Olympics.

At this winter Olympic Games, carbon nanotubes were used on skiing boards of American Alpine skiers.

Each layer of ski is fixed by carbon nanotubes to stabilize the uneven pavement and prevent it from falling down.

At the same time, experts also said that using this material made of skis, "how you use will not be easily damaged."

< /p >

Ren Hongxuan, deputy director of the science and Technology Management Department of the national nanoscience center, told reporters that nano technology can play an important role in the Olympic Games, thanks to the characteristics of nanotube materials, such as light weight, strong wear resistance and reduced sliding resistance. P

Skiers will encounter unexpected bumps in competitions, while nanotubes can disperse and slow down vibrations.

< /p >

< p > "nanotechnology is not new to skiing, and many years ago, such technology was developed."

Ren Hongxuan said that researchers had previously coated nano boards on the bottom of ski boards to maintain their firmness and stability.

< /p >

< p > in fact, apart from these, there are still many scientific and technological elements that shine in the Winter Olympic Games: powerful wireless networks ensure that the results of the games are quickly and automatically pmitted to the Internet, and you still know who is the champion if you haven't heard the cheers of the audience.

The advanced timer can not only record the speed of the runners, but also provide acceleration, gravity analysis, and even locate the players in the arena.

In addition, the LED display highlights the highlights of the competition. Vinyl nitrile materials are used to make new helmets. The new zipper with better closure makes the waterproof performance of sportswear greatly improved. Behind the hidden sleigh without sleigh is the R & D team of Ferrari, Audi, McLaren and BMW.
