LEONID TROFIMOVICH DVORNIKOV IS 85

On February 6, 2019, Professor of the Department of Mechanics and Mechanical Engineering of the Siberian State Industrial University (Novokuznetsk) L.T. Dvornikov turned 85 years old. Leonid Trofimovich Dvornikov is an Honored Scientist of the Russian Federation, Doctor of Technical Sciences, Professor, founder of the scientific school "Theory of the structure of mechanical systems and the practice of its use in the synthesis of complex machines, including mining and metallurgical ones."
The creative activity of L.T. Dvornikov can be conditionally divided into three stages: Tomsk, where the scientific school of Professor O.D. Alimov already existed; Frunze and Novokuznetsk, where scientific schools were created by L.T. Dvornikov in the main scientific areas developed by him.
In 1958, L.T. Dvornikov graduated with honors from the Tomsk Polytechnic Institute in the specialty of mining electromechanics and remained in teaching, while simultaneously studying in graduate school. At the initial stage, Leonid Trofimovich's scientific interest was connected with the modes of drilling rock using rotary machines, and since 1963 he has been engaged in a deep study of the theory of mechanisms and machines, to which he devoted his entire subsequent life.

In 1965, L. T. Dvornikov was invited to head the Department of Theory of Mechanisms and Machines at the Frunze Polytechnic Institute (Frunze, Kirghiz SSR), where he created a new scientific direction in the theory of mechanisms and mining machines used in the extraction of minerals. In 1974, Leonid Trofimovich defended his doctoral dissertation, was elected dean of the mechanical engineering faculty and became director of the research institute for mechanical engineering problems. From 1965 to 1989, he prepared 20 candidates of science in Kirghizia, published more than 200 scientific articles, and received more than 100 author's certificates for inventions. For his contribution to science and the training of highly qualified personnel for the republic, he was awarded the USSR Order of Friendship of Peoples (1986), was awarded the title of laureate of the State Prize of the Kirghiz SSR (1976), the title of Honored Scientist of Kirghizia and was elected as a Corresponding Member of the Academy of Sciences of Kirghizia. Later in 2004, by decree of the President of Kirghizia A.A. Akayev, L.T. Dvornikov was awarded the Order of Danaker for his great contribution to science and technology in the republic. Many students of L.T. Dvornikov's Frunze school became directors of large enterprises, firms, rectors, deans and heads of departments, created scientific schools themselves, and educate their students. Working in Kirghizia, L.T. Dvornikov did not break close scientific ties with Kuzbass, in particular with the Kuznetsk Machine-Building Plant (KMZ), where with his participation and under his scientific supervision many high-performance drilling units for coal mines were created. Eight KMZ engineers, engaged in improving mining machines under the scientific supervision of L.T. Dvornikov, defended their candidate dissertations and brought the equipment produced at KMZ up to world standards.

In 1989, Leonid Trofimovich was invited to work at the Siberian Metallurgical Institute as the head of the department of the theory of mechanisms and machines and the basics of design. Over the past 27 years, he created a scientific school on the "Theory of the structure of mechanical systems and the practice of its application in the synthesis of complex machines, including mining and metallurgical ones." On the subject of this school, L.T. Dvornikov prepared for defense five doctoral and 25 candidate dissertations, received about 200 patents for inventions, published 10 monographs and more than 300 scientific articles. Since 1992, he organized the training of specialists in the new specialty "Dynamics and strength of machines." By now, more than one hundred bachelors and engineers of the highest qualification have been graduated for the needs of Kuzbass, working at enterprises in the city of Novokuznetsk and the Kemerovo region. Most of these specialists are the authors of inventions, important technical projects, and scientific articles. A number of L.T. Dvornikov's inventions have inter-industry significance, some of them served, in particular, as the basis for the development of State Standards (GOSTs). At the request of the military-industrial complex, L.T. Dvornikov developed unique underground mining robots, protected by 37 inventions. The drilling modes used on the Luna-24 spacecraft were tested on the stands invented by L.T. Dvornikov. Many of L.T. Dvornikov's inventions are valued by users as a major contribution to technical progress, expressed in solving innovative problems that have no analogues in world practice. Actively participating in the innovation and invention competition held by the Kemerovo Region Administration (2003-2006), L.T. Dvornikov was awarded four first-degree diplomas for his inventions, medals "For Special Contribution to the Development of Kuzbass" of III and II degrees, and a medal "For Service to Kuzbass". His inventions were awarded silver and bronze medals at the International Coal and Mining Exhibition. L.T. Dvornikov's developments were demonstrated at the International Exhibition in China in 2007 (Shenyang) and received high praise; five international contracts for their implementation were concluded. During 2004-2008. Twenty technical solutions patented by Dvornikov found direct use in the Kuzbass mines.

His long-term fruitful inventive activity has been repeatedly noted with departmental Certificates of Honor and gratitude. Thus, for especially active participation in the Kuzbass innovation program, L. T. Dvornikov was recognized as the best head of department in the Kemerovo region in 2004. For innovative technical developments for the coal mines of Kuzbass, at the suggestion of Yuzhkuzbassu-glya, L. T. Dvornikov was awarded the Miner's Glory badge of all three degrees by the decision of the Ministry of Energy of the Russian Federation. By now, Leonid Trofimovich Dvornikov is the author of more than 350 inventions, more than 600 scientific articles, and ten monographs. He has prepared ten doctors of technical sciences for defense, about 60 candidates of sciences, and has trained and graduated hundreds of highly professional engineers. Over the years, he has been awarded the Medal of the Order of Merit for the Fatherland, 2nd class, and the Order of Honor (2010). In 1970, he was awarded the Medal of Valiant Labor.
