State Key Laboratory of Tribology, Department of Mechanical Engineering, Tsinghua University, Helps Ice Making for the 24th Winter Olympic Games
On February 20, 2022, the 24th Winter Olympics closed perfectly. The Beijing Winter Olympics provided a visual feast for the global audience. In response to General Secretary Xi Jinping's call that "China's ice and snow sports must take the road of scientific and technological innovation", Associate Professor Ma Liran and his team members (Dong Sing, Liu Yuan, Shi Zhifeng and Huang Zhitao) from the State Key Laboratory of Tribology, Department of Mechanical Engineering, Tsinghua University contributed to the preparation of ice surface in the Winter Olympics. The team conducted comparative analysis of the water quality of different venues and systematically studied the influence of ice-making water composition on the friction coefficient, using the super-slip mechanism, an environmentally friendly and green ice-making formula is proposed, and the field test friction coefficient is reduced by 30% compared with the original ice surface. It provides important technical support for more uniform and better ice preparation for the Winter Olympic ice project.
It is reported on the website of the International Tribology Council.
On February 4, 2022, the 24th Winter Olympic Games opened at the National Stadium in Beijing providing a visual feast for the global audience.
Liran Ma and her coworkers, from the State Key Laboratory of Tribology at Tsinghua University in Beijing, China, contributed to the Winter Olympic Games using tribological technologies. Inspired by the concept of superlubricity from hydration effect, the composition of water used to make ice in rinks, was well designed and regulated. They have succeeded with reducing the friction coefficient of ice by 30%, and getting more uniform and stable ice. Friction measurements were carried out in both laboratory and field tests. Field tests showed that the rinks in which ice was made by regulated water had better uniformity and lower friction. Athletes have broken Olympic records on many rinks, proving the rinks are fast venues.
