Xie Youbai

Machine Design and Theory, Tribology



Xie Youbai, male, was born in Shanghai in September, 1933. In 1955, he graduated from Jiao Tong University (Shanghai) with a specialty of Internal Combustion Engine Manufacture, and then was engaged in the teaching and research work concerning Mechanism and Machine Theory. In 1957, he moved to Xi'an with the University and worked there. He was appointed as the first supervisor of Ph.D. students in the field of Machinery Science at Xi'an Jiao Tong University in 1984 and Professor in 1986. Two years later, he was appointed director of Theory of Lubrication and Bearing Institute. Besides, he was vice-chairman of the first, second and third Council of Tribology Institution of Chinese Mechanical Engineering Society (CMES), and was appointed chairman in 1992. He is also dean of the Academic Committee of National Tribology Laboratory, Tsinghua University and member of Academic Degree Committee of State Council. Xie is the deputy editor on Journal of Tribology, member of the editorial board of Chinese Journal of Mechanical Engineering, China Mechanical Engineering, Journal of Engineering Tribology (Proc IMechE Part J) etc., and a part time professor of Shanghai Jiao Tong University, Southwestern Jiao Tong University, Northwestern Polytechnical University, etc. He was in the first group to be elected academician of the Chinese Academy of Engineering in 1994.

Professor Xie has been occupied with research and education in Machinery Science and Tribology for about 40 years. He has undertaken dozens of national key projects. He has been awarded over ten different prizes, including a National Natural Science Award and several Ministry Awards and Province Awards. He has published more than 100 papers, books, and about 16 students have obtained their Doctoral degrees and 31 have obtained their Master's Degrees under his supervision.

Professor Xie has made theoretical and practical studies in many different fields of Tribology, including lubrication, control, reliability, knowledge acquisition, databank and expert systems, and has made many achievements in those fields. Based on the previous simple systems, he developed the approach and proposed a basic framework of the engineering systems —tribo-systems. Furthermore, he has achieved many important findings, both theoretical and practical, in the area of tribological and dynamical design of rotor-bearing systems for large turbine generator sets and high speed rotating machinery.
