After Yan Wengang took away the bronze medal of the men's steel frame snowmobile and achieved a historic breakthrough for China, the Winter Games Center of the State General Administration of Sport sent a congratulatory message: "Yan Wengang is not afraid of strong hands, dares to fight, and in the case of the world's masters playing well, he won a valuable bronze medal for the delegation with a score of 4 minutes and 1 seconds 77, which is the first steel frame snowmobile winter Olympic medal in the history of the mainland; Yin Zheng ranked 5th with a time of 4 minutes 2 seconds 13, and created a track departure record with a time of 4.58 seconds, and skated out of the world speed on the Chinese track." ”
In the race, Yan Wengang skated a perfect performance of a top speed of 129.71 km/h and an average speed of about 120 km/h in the fourth round, surpassing the original third runner in 1 minute, 0 seconds and 15 seconds, and winning a valuable bronze medal.
Yin Zheng also created a track departure record, behind these two "China's firsts", it is inseparable from the escort of scientific researchers. In the process of preparing for the war, Chinese athletes even used aerospace technology.
In the process of preparing for the Beijing Winter Olympics, the national team used aerospace technology.
At the National Ice and Snow Sports Training and Scientific Research Base of Beijing Sports University, the team members train in the six-degree freedom training system, which can simulate the real field environment of steel frame snowmobiles, snowmobiles, bobsleighs, alpine skiing, cross-country skiing and other projects through the six-degree freedom platform sports and synchronous video screens, helping athletes to remember the track information in advance and form muscle memory.
The preparation of China's steel frame snow team also used wind tunnel technology.
According to Professor Li Bo, director of the wind tunnel laboratory of Beijing Jiaotong University, the steel frame snowmobile is the sport that is most tested in the wind tunnel.
It is reported that the wind tunnel is one of the most effective technologies for aerodynamic research, and the traditional ice and snow powers have introduced wind tunnels into sports training methods.
In the comprehensive wind tunnel hall, the national team can simulate a variety of real competition scene environments during training, with precise characteristics that are difficult to achieve in conventional land training, and the team members adjust their movements more accurately through such training.
In addition, the team of Professor Huo Bo of the School of Astronautics of Beijing Polytechnic Institute has developed a set of technical systems based on three-dimensional motion capture, automatic attitude recognition and ultra-wideband, which realizes the motion analysis of bobsleigh in the departure section and the curve section, the attitude kinematics of the athletes in the departure section and the analysis of human dynamics.
According to the official introduction of Beijing Institute of Technology, based on video integration and deep learning technology, the application of surveillance video carried out the kinematic parameter analysis of the athlete's whole slide, accurately obtained displacement, speed and acceleration information, accurately analyzed the athlete's push and pull on the sled, and then fed feedback on the push and pry training, which effectively improved the training effectiveness.
At the same time, high-speed cameras are set up at both ends of the curve to effectively capture the in and out of the bends of the athletes in the training and test competitions, and scientifically calculate the kinematic parameters of the curves, help the athletes and coaches find the optimal trajectory, analyze the sports process at a glance, and help Chinese athletes achieve a historic breakthrough from scratch in this project.
