The features of the motion of a mechanical system with one degree of freedom are considered, in the case of asymmetry of its elasticity characteristics, with a vertical impact by a falling solid. It is shown that as a result of asymmetry of the characteristics, the maximum movements of the system downward in the direction of the impact velocity may be less than the maximum displacement of the system upward. Conditions are defined when this inequality holds. The conditions depend not only on the proper parameters of the oscillatory system, but also on the mass and velocity of the impacted body. The investigation was carried out on the assumption that the mechanical impact is absolutely inelastic, when after an instantaneous collision of solids they move together with the same speed and the same acceleration

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.
