The article examines the deformation processes of viscoelastic systems, which are widely used in food technologies as part of transport-technological and packaging equipment. The working components of such systems (stops, guides, stoppers, springs, dampers, friction units, etc.) change their shape and dimensions under external loads, affecting the efficiency of the equipment and energy consumption. Methodological approaches are proposed for calculating the work and energy characteristics of elastic and viscoelastic elements, taking into account their structural and rheological properties.
Based on the equations of rheodynamics, the work of elastic forces during compression and tension is analyzed, showing that the work depends on the square of the elongation and is independent of the trajectory or duration of the process. To account for the time-dependent characteristics of deformation, a viscous element – a damper – is introduced into the mechanical models, allowing the description of gradual spring deformation under constant or variable loads. Differential equations for parallel and series connections of elastic and viscous elements are considered, and their solutions and expressions for calculating work, deformation rate, power, and energy expenditure are obtained.
Particular attention is given to cases where the deformation forces vary according to a linear or nonlinear law, including exponential, which corresponds to real conditions in packaging processes. Graphical dependencies are presented, illustrating the nature of deformation under different types of loads. The obtained relationships can be used to optimize the energy parameters of technological equipment, improve the reliability and durability of its working components, and enhance the designs of transport-technological and packaging lines.

Publisher Vinnytsia National Agrarian University
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 119 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Ihor Kupchuk, Candidate of Technical Sciences, Associate professor, Associate Professor of the Department of Engineering Mechanics and Technological Processes in the Agricultural Industry Faculty of Engineering and Technology Vinnytsia National Agrarian University 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.
