Prof. Dr., Institute of Power and Transport Machinery Engineering, Vytautas Magnus University, Kaunas, LithuaniaThe current stage of development of tribology is characterized by the creation of methods for calculating friction pairs for wear. It has long been considered that the creation of such methods is impossible due to the extreme complexity of wear processes. If there are no calculation methods, respectively, there will be no methods for predicting wear resistance and durability of tribosystems. Development of analytical methods of calculation of wear resistance of tribosystems is complicated by nonlinearity of models of wear owing to difficult interrelations of mechanical, thermophysical and frictional properties. To obtain correct results, analytical methods for calculating tribosystems require proof by numerical methods using powerful computing systems. Cylindrical tribosystems of sliding in many power, technological and transport machines are one of the main elements that determines the durability and reliability of the machine as a whole. Therefore, the creation of a system of computational and experimental methods and numerical models for predicting the durability of cylindrical sliding tribosystems, taking into account the variety of operating conditions is an important scientific[...]Vytauto Didžiojo universitetasŽemės ūkio akademij
