清華大學機械系摩擦學國家重點實驗室助力第24屆冬奧會制冰
最新動態(tài)
2022年2月20日，第24屆冬奧會完美閉幕，北京冬奧會為全球觀眾奉獻了一場視覺盛宴。響應習近平總書記提出的“中國冰雪運動必須走科技創(chuàng)新之路”的號召，來自清華大學機械系摩擦學國家重點實驗室的馬麗然副教授與其團隊成員（董唱、劉媛、石志峰、黃致韜）為冬奧場地冰面的制備做出貢獻，團隊對不同場館水質進行對比分析，系統(tǒng)研究了制冰水成分對冰表面摩擦系數(shù)的影響，并利用超滑機制，提出了一種環(huán)保綠色的制冰配方，現(xiàn)場測試摩擦系數(shù)較原冰面降低了30%。為冬奧冰上項目更均一、更好的冰面制備提供了重要的技術支持。

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.
