"There is still a gap between China and the top countries of ice and snow eports!" Reporters often hear such a comment at the Beijing Winter Olympics.
Many ice and snow events in China started late and have a weak foundation, but at the Beijing 2022 Winter Olympics, Chinese ice and snow athletes have achieved many substantial leaps from "scratch" - not only to participate in the entire event, but also to achieve good results. The gap is narrowing, and the help of technology is indispensable.
"Secret Weapon" Special Wind Tunnel
How to let a group of athletes from "cross-item selection" quickly master the sport? How to make them better handle the wind?
Using artificial intelligence assistance system, real-time collection of athletes' jumping angle, aerial posture, speed, distance and other data, to provide better scientific and technological support to the coaching team... This is the chief scientist of the national key research and development plan "Science and Technology Winter Olympics", from Shanghai Sports Liu Yu of the academy, and what the team he is responsible for is doing.
Laiyuan National Ski Jumping Training and Scientific Research Base has overcome another difficulty: ensuring the "quantity" of training. In the past, Chinese athletes had only one option - training abroad, with high risk of injury and low efficiency. With the completion of the Laiyuan National Ski Jumping Training and Research Base, all the problems have been solved. The base is also equipped with the world's largest and China's first dedicated ski jumping wind tunnel laboratory, which is the "secret weapon" for improving the training level of athletes.
"Head-to-toe" technology armed
"If you want to do a good job, you must first sharpen your tools." In the past, in the steel frame snowmobile arena, the competition uniforms, helmets and spikes designed and manufactured by European and American sports brands dominated the mainstream, and it was difficult for Chinese athletes to buy suitable equipment. At the Beijing Winter Olympics, the equipment of the sled athletes, from helmets to competition suits, to gloves and spikes, shone from head to toe with the "Science and Technology Winter Olympics".
During the Beijing Winter Olympics, researchers organized a "helmet research". The aerospace-grade carbon fiber material used to make the helmet is 5 times as hard as steel, but only half as dense as steel. The helmet is customized according to the characteristics of the athlete's head. Yin Zheng's "Dragon and Tiger Crown" is full of personality, fully demonstrating the style of young Chinese athletes.
The spikes independently developed by the domestic brand Anta. All the nails are made of 3D printed titanium alloy structure, which is lighter in weight and can effectively reduce wind resistance. After repeated tests, this combat boot can averagely speed up compared to other brands in the starting stage. 0.023 seconds. The starting of the cart is the most important technical link in the steel frame snowmobile competition. It is of great significance to be able to increase the speed at this stage.
Simulation training - Check for gaps
How do athletes usually master the best technical movements in training? The answer is to combine simulation training with high-tech assistance such as wind tunnel technology to clarify the direction for athletes' progress.
From 2020, the comprehensive wind tunnel hall of the Erqi National Ice and Snow Sports Training and Research Base in Beijing will be officially opened. Chinese athletes can conduct wind tunnel simulation training at their doorstep. Combined with the technical movements captured by digital cameras, it can help athletes reduce wrong action bands. Come to the risk, find the state with the least wind resistance, so as to obtain better results.
In addition, the six-degree-of-freedom technology is also used in the steel frame sled training system. The so-called six degrees of freedom means that the platform can achieve translation in three dimensions, up and down, left and right, and front and rear, and rotation in three dimensions of pitch, roll, and yaw. The whole system is like a simulation game, which enables athletes to collect richer real-time training data in a safer training environment.
"Fast, Protective, Warm and Beautiful" Gears R&D in China
At the Beijing Winter Olympics, short track speed skating star Wu Dajing showed off the anti-cutting design of many parts of his uniform. This is the National Winter Sports Clothing and Equipment Research and Development Center. After referring to more than 100 kinds of fabrics around the world, it was finally successfully developed. A kind of anti-cutting fabric produced, using the latest 360-degree whole body anti-cutting technology, the anti-cutting strength is 15 times that of steel wire.
In order to provide Chinese athletes with equipment that is more in line with their own characteristics, the National Winter Sports Clothing and Equipment R&D Center has solved the four key technical problems of "fast, protective, warm and beautiful" for professional competition clothing, and realized the realization of racing clothing, protective materials and equipment. , low temperature protection materials and equipment, technical projects and clothing four types of product innovation.
The competition uniform "Costen" designed by the R&D team for the figure skating team is a concentrated expression of the word "beauty". In the past four years, the Beifu team has designed a total of 170 sets of competition uniforms for the figure skating team. Figure skating is a sport that embodies art, and the design of figure skating competition suits is also a comprehensive artistic creation process. Designers must not only understand the athlete's program, but also take into account the athlete's body, personality, preferences, aesthetics, etc. Each piece of clothing is unique.
