Many years of research have shown that when working on a tractor on soft soils, characteristic of almost most farmers. operations, there is a deep immersion of the wheel hooks in the soil layer. Immersed in the ground, the hooks press it in the horizontal direction opposite to the movement of the tractor. As a result, there is a decrease in the translational speed of its movement.
Research in this direction, taking into account the conditions of movement of wide-track agricultural equipment in the wake of a constant technological track, has been conducted by scientists is extremely insufficient. And in considering the problem of developing the scientific basis for the use of a bridge tractor, some scientists believe [13] that the issues of their theory and technological properties require further development and development.
One of the ways to reduce the energy intensity of production processes in agriculture is the transition to track and bridge agriculture using wide-track (portal) vehicles (or bridge tractors), which are specially adapted for this purpose. Since their movement in the footsteps of a constant technological track is characterized by both an increase in traction and coupling qualities, and a significant decrease in resistance to their rolling. Because of this, bridge tractors are able to develop a higher level of traction and energy in contrast to a traditional tractor, which moves on agricultural land. agrophone. The issue of determining the required level of energy saturation of wide-gauge (portal) vehicles becomes relevant in order to create a system of their aggregation and practical use. As a result of the conducted researches it is established that the required level of energy saturation of the bridge tractor should be at the level of 23.5 kW / t. Under conditions of sufficient adhesion of the engines of a wide-track agricultural vehicle with the supporting surface of the soil trace of a constant technological track allows it to develop traction at the level of 6.37 kN per ton of its operating weight.

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.
