World Tribology Congress Settled in China for the First Time Liu Yandong Letter of Congratulations

　　Tsinghua News Network, September 20(ReporterLi JingCorrespondentYu Jianwen) On the morning of September 18, the 6th World Tribology Conference (The 6th World Tribology Congress) opened at the Beijing International Conference Center. Vice Premier Liu Yandong sent a special letter of congratulations. More than 2000 Chinese and foreign tribologists gathered in Beijing to discuss the world The sustainable development of tribology science, engineering and technology. This conference is the first time that the World Tribology Conference has been held in China since its establishment 20 years ago. It is hosted by the Tribology Branch of the Chinese Society of Mechanical Engineering and undertaken by Tsinghua University.

In his congratulatory letter, Liu Yandong extended warm congratulations on the convening of the conference and extended a sincere welcome to experts and scholars from all over the world. Liu Yandong pointed out that as an interdisciplinary subject, tribology research involves a wide range of fields, which is of great significance for energy saving and consumption reduction, environmental protection, and promoting sustainable and healthy economic and social development. The Chinese government has always adhered to the concept of sustainable development and building a conservation-oriented society, attaches great importance to scientific research and industrial development in tribology-related fields, and is willing to work with other countries in the world to make unremitting efforts to promote the development and progress of tribology.

Liu Yandong said that the World Tribology Congress is the largest and highest-level comprehensive event in the field of international friction. The conference was held in China for the first time, which not only built an effective platform for promoting exchanges and cooperation in the field of international friction, but also provided an important window for displaying the achievements of technology and industrial development in the field of tribology in China. I sincerely hope that the participating experts and scholars will take this opportunity to have in-depth exchanges, inspire inspiration, and work side by side to make new contributions to the development of world tribology and the promotion of human well-being!

In her speech, Chen Xu briefly introduced the basic situation of Tsinghua University. She pointed out that after more than 50 years of development, tribology has formed a mature theoretical framework and a perfect industrial chain, and a number of excellent Chinese and foreign scholars have emerged, contributing to the progress of human science. The State Key Laboratory of Tribology of Tsinghua University has made positive contributions to the development of tribology and played a supporting role in the construction of related disciplines in the school. Chen Xu said that at this International Tribology Conference, tribology experts from all over the world gathered together to collide with sparks of ideas. This is a scientific feast in the field of tribology. I wish the conference a complete success.

Yang Wei expressed his heartfelt congratulations on the first settlement of the World Tribology Congress in China. He said that tribology research is related to economic and social development. In recent years, the National Natural Science Foundation of China has supported many teams, including Tsinghua University, and achieved fruitful results. In the future, it will further support the development of China's tribology, promote interdisciplinary research, promote international cooperation and innovation, and make tribology in my country's modernization and development. Play a better role in the development of world science and technology.

Academician Luo Jianbin said that drilling wood for fire made human beings move towards civilization, wheels replaced sliding friction with rolling friction, and bearing inventions closely related to tribology promoted the development of modern industry. Today, from aerospace to transportation, bridge engineering, to deep ocean diving and deep earth exploration, almost all super projects have tribological contributions behind them. This conference will focus on the development needs of tribology related to energy and green, pay attention to new fields, and strive to create a more efficient, safe and green earth home.

Professor Ali Eldaimir, the new president of the society, introduced the development status and future vision of the International Society of Tribology. He thanked every tribologist for his hard work and Tsinghua University for its careful preparation. He said, "We are gathered in Beijing to enhance exchanges, accelerate innovation and work together to build a home on the planet. I am confident that the results of the five days of the conference will have a lasting impact on the development of disciplines and industries in the coming years."

The five-day conference aims to summarize the recent research results in various directions in the field of tribology, explore the future research direction of tribology, and enhance the connection between the basic research and applied research of tribology and the industry.

The participating experts discussed and exchanged in the sub-forum.

2022 tribologists from institutions of higher learning, scientific research institutes, companies and enterprises in China, the United States, Japan, the United Kingdom, Germany, France and other countries registered to participate in the conference and received a total of 1398 submissions. According to the different directions of tribology, the conference set up friction science, wear and surface engineering, lubrication and lubricant, biological and bionic tribology, industrial tribology, engine and transmission tribology, industrial friction system, friction detection and monitoring, and the forum of young friction scholars. Through keynote reports, lectures, seminars and other forms, academic discussions and exchanges were conducted around new ideas, new theories, new methods and new applications of tribology.

Tribology is a science that studies friction, wear and lubrication, and occupies a core position in the fields of machinery, energy, and electronics. The study found that about 30% of the world's disposable energy is consumed by friction every year, about 60% of the machine parts fail due to wear, and about 50% of the malignant accidents of mechanical equipment stem from lubrication failure and excessive wear. The continuous progress of tribology is creating a more efficient, safe and green earth home.

The World Friction University began in 1997 and is held every four years. The first five sessions are held in the United Kingdom (London), Austria (Vienna), the United States (Washington), Japan (Kyoto) and Italy (Turin). China stood out in the competition with the United States, Sweden, South Africa and other countries and won the right to host the conference, thanks to the rapid development of national scientific and technological strength in recent years. Since 2013, in the field of tribology, the number of American "Science Citation Index" (SCI) papers in China's tribology has surpassed the United States and ranked first in the world, more than twice the third. China's research in the field of tribology, such as super-slip, harsh working conditions tribology, biological and bionic tribology, has reached the world's advanced level.

Tsinghua University's research on tribology is in an international leading position and enjoys a high international reputation. The National Laboratory of Tribology of Tsinghua University was founded in 1986. It passed the national acceptance in November 1988 and was officially opened to the outside world. It is one of the first state key laboratories in the field of mechanical engineering in China and Tsinghua University. In the past 10 years, the State Key Laboratory of Engineering ranked first in a row. In recent years, the laboratory has made a series of important achievements in chemical mechanical polishing and super lubrication research for integrated circuit manufacturing.
