ИНФОРМАЦИЯ M. Vukobratovic′ MEMORIES APROPOS 75 YEARS OF ACADEMICIAN KONSTANTIN VASIL’EVICH FROLOV KONSTANTIN VASIL’EVICH FROLOV, University Professor and Full Member of the Russian Academy of Sciences (RAS), has in his longtime career held a number of outstanding working posts and honorary duties: Director of Mechanical Engineering Research Institute, Director of the biggest institute of mechanical engineering “A.A. Blagonravov” of Russian Academy of Sciences (RAS), Academiciansecretary of the Division for Mechanics and Process Control of the Soviet (Russian) Academy of Sciences, Chairman Mechanical of the Council for Processes of RAS, and Vice-president of RAS. <...> Having Engineering and Technological started his scientific career with research in the domain of conventional and special problems of machines and mechanisms theory, later on he focused his attention on the issues of vibration thechnology study and refinement and the problems of protection of man-operator, where he was one of the founders of a novel advanced research trend of biomechanics. <...> At the same time, during all the period of his creative activity, K.V. Frolov has been paying much attention, energy and efforts to study, formulation and solution of the actual and urgent problems of scientific and technical progress, intensification of the work of the research staff, search for the optimum techniques interconnecting science, technology and industry. <...> Being the Director of the Mechanical Engineering Research Institute (MERI) for a long time and taking active part in the work of the RAS, as well as of numerous government and public organizations, Academician K.V. Frolov has made a profound contribution to the development of theoretical and experimental research, to training of highly qualified scientific co-workers, establishing of new research centres and scientific associations, and strengthening of international collaboration of scientists from different countries of the world. <...> The wide creative scope of the Academician K.V. Frolov’s interests covers a large number of scientific and special technical issues. <...> He obtained fundamental results in the field of dynamics of machines; he laid down scientific foundations of modification, refinement and perfection of machines according to the criteria of vibration loading and vibration safety; he developed theory of vibration technology and equipment which became a scientific basis for high-performance machinery design based on mechanical principles, establishing thus a school of non-linear dynamics of machines. <...> He <...>
