The problems of the dynamics of elastic systems under the action of a mobile inertial load and certain features of mechanical and corresponding mathematical models of problems of this class that can be attributed to non classical problems of mathematical physics are considered. A brief overview of the problems whose solutions are obtained on the basis of the generalized method of separation of variables is given, which in some cases makes it possible, in the framework of the initial assumptions, to construct exact solutions and on their basis to study the nature of the oscillations and stability of the system. The study of the mathematical model is performed on the basis of the method of the two-wave representation of motion in the form of two 

groups – proper and accompanying oscillations. The role of the accompanying oscillations, which are caused by the mobile inertial load, vary significantly depending on the speed of the mobile load and the ratio of the fixed and fixed mass of the system. The oscillations and stability of a reinforced rectangular plate are investigated taking into account the discreteness of the location of the ribs along which the mass load flows.


Keywords: dynamics, mobile inertia load, frequencу, critical speed

History of journal:

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published  94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M  PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering  and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
