The team performed medical MRI scans on eight athletes in ice and snow sports and six general personnel of different body sizes, collected nearly 1,000 tomographic images for each individual, and composed a complex data acquisition and processing system to measure the motion of 14 body segments of the dummy by installing about 40 sensors on the dummy and taking advantage of the traditional field technology of highly dynamic motion body posture measurement and control. characteristics.

At present, China does not yet have a set of perfect product standard systems, core technology and testing standards, most of which are in the hands of foreigners. Therefore, ice and snow sports equipment mainly rely on imports. The research and development results will form a set of industrial standards suitable for China’s national conditions and international mutual recognition, breakthrough bottleneck technology in the ice and snow sports equipment industry.

04 Let the big ice rink play flash mob

In order to promote ice and snow sports, high-tech technological innovation and product development are indispensable. Zhu Rui, a faculty member of the School of Aerospace Engineering of BIT, led the research work on key technologies for the study of the mobile detachable artificial refrigeration ice rink.

The team made a number of 1m x 6m ice panels, which are equipped with temperature and humidity sensors. The ice rink assembled by such "small-sized" ice plates can achieve the goal of rapid construction of different areas of the rink, but also to achieve full-time all-round ice rink monitoring and intelligent management.

211030(14).png

At present, the team cooperates with Huaxi Ice to build a 30m x 60m standard mobile disassembled artificial cooling ice rink in less than 46 hours, with a service life of more than 10 years and a recycling rate of more than 98% for more than 5 kinds of ice sports, such as speed skating.

05 The Never Fading Ice and Snow

Since snow and ice are prone to melt at high temperatures, this will hinder the popularity of snow and ice sports in the region and time, and the integration of the snow and ice industry with science and technology, culture and history. Therefore, the development of the 2022 Beijing Winter Olympics and snow and ice industry urgently needs to develop new non-melting snow and ice materials.

211030(15).png

In order to solve the problem of traditional ice and snow melting easily, the student gel ice and snow team under the guidance of Professor Zhang Kai from the School of Aerospace Engineering of BIT has successfully developed a non-melting gel ice and snow material. This new ice and snow material has many advantages such as the sight and feel of natural ice and snow, good biocompatibility, low cost, and reusability. The team has two key technologies to regulate the microstructure to lock the water molecules and the component regulation to create super tough gel ice and snow. The team has developed four major products: ice panels and ice walls, gel ice paintings, ice and snow-themed cafe items and decorative souvenirs.

In May 2021, the project won the special prize of the 11th Challenge Cup extra-curricular academic science and technology works competition for college students in the capital, "Science and Technology Winter Olympics".
