Laboratory History

The laboratory of tribology was established by two members of the Academy of Sciences, Ishlinsky A.Y. and Rebinder P.A., in 1972. Research areas selection was influenced by such outstanding scientists as Kragelsky I.V. and Galin L.A. The first laboratory head was Professor Mihin N.M (1972-1989), the second head was PhD Dobychin M.N. (1989-1996). Since 1996 the laboratory has been working under the supervision of Goryacheva I.G., member of the Academy of Sciences and Doctor of Physical and Mathematical Sciences. She started working at the laboratory as a juniour scientist in 1973. During this laboratory operation the staff has conducted theoretical and experimental researches in various tribology fields; they also have developed unique instruments and tribological testing methods.

International and Russian Scientific Contacts

The researches conducted at the laboratory are supported by grants from RFFR (Russian Fund for Fundamental Research), grants from the President for Promoting Leading Scientific Schools and Young Scientists and by RR (Russian Railways).

The Laboratory together with All-Russian Scientific Research Institute of Railway Transport (ASRIRT) conducts regular researches on the issue of interaction between a railway wheel and a rail. This research has resulted into development of computer system (tribodynamic model) connecting railway carriage dynamics to wheels and rails contact characteristics and wear. Besides, there are also some researches on developing new materials for railway machinery elements.

Moreover, the laboratory also conducts shared researches with the Institute of Metal and Polymeric Systems of the National Academy of Sciences of Belarus, some institutes of the Russian Academy of Sciences (IMS (A.A. Blagonravov Institute of Machine Science), IGP (A.M. Prokhorov Institute of General Physics), IME (A.A. Baikov Institute of Metallurgical Engineering), IOC (A. N. Nesmeyanov Institute of Organoelement Compounds), etc.) and with MISHLEN company (France).

Achievements: Awards, Prizes, Titles of Honour, etc.

In 2009 Goryacheva I.G. was awarded with Large International Golden Medal in the Field of Tribology. This medal is given by the International Tribology Association.

In 2007 Goryacheva I.G. was granted with the Russian Federation Government Award in Science and Technology "for developing and introducing into mechanical engineering industry long-life, large-scale nonpolluting sliding friction units featuring premium tribological features".

In 2005 Goryacheva I.G. was honoured with Olympya National Award of Women Achievements Public Recognition in Russia in the Sience Studies category.

In 1990 Soldatenkov I.A. was awarded by the Academy of Sciences of the USSR with a medal for young scientists.

In 1979 Goryacheva I.G. was given the Award of Leninsky Komsomol (young communists' league).
