Based on the study, some analogies in the problems of statics and dynamics of elastic elements of structures under the action of moving inertial load are considered and substantiated. The obtained analogies allow in some cases to significantly simplify the procedure for constructing solutions of dynamic problems of mechanics. In some cases, the obtained analogies allow to determine the initial values of frequencies and critical values of load speeds, which are further specified in the calculation process. Mechanical and corresponding mathematical models of mechanical system "Sieve - grain heap" for sifting of grain mix are developed. Differential equations of motion of the grain mixture in an inclined sieve are derived. The obtained mathematical model is studied and the kinematic and geometric characteristics of the sieve and its modes of operation are substantiated. Mechanical and corresponding mathematical models of bimaterial fracture mechanics with between phase cracks and different electromagnetic conditions on their shores are considered. Analytical solutions of the problem on the basis of which the character and features of destruction of such materials are investigated are constructed. According to the results of the research, reports were made at international scientific conferences, articles were published in the conference proceedings of professional publications and publications that are part of international scientific databases.
