VIBRATION TECHNOLOGIES IN THE RESTORATION OF THE WORKING BODIES OF AGRICULTURAL MACHINES
The paper deals with the use of vibration vibrations in the restoration of the working bodies of agricultural tillage machines operating under conditions of increased abrasive wear.
The analysis of the existing methods of their restoration is carried out, the substantiation of the use of vibration hardening treatment in repair production is given.
The research carried out on the choice of the optimal parameters of vibration strengthening of the cutting working bodies contributes to an increase in the wear resistance and reliability of soil cultivation equipment.
According to the research results, the change in hardness along the depth of the surface layer of cutting elements of the following agricultural tillage machines: plow shares, opener discs of grain seeders and cultivator paws was established.
Optimal values of the main parameters of vibration processing of cutting elements of the specified working bodies are experimentally determined and substantiated, which reduce the amount of their wear: amplitude A and vibration frequency of the processing tool n, hardening time t.
The change in the magnitude of linear wear along the width of the cutting elements of these parts is shown, as well as data on the intensity of their wear.
Experimentally obtained data on the absolute and relative wear of the diameter and thickness of the blade of the opener discs, which made it possible to choose a more efficient technology for their restoration.
According to the research results, it was found that the specified parts of soil cultivation equipment had the least wear value; they were restored by welding tires, plates or segments from steel 45, followed by surfacing with sormite and strengthened by vibration deformation.
The results of the work will be used to develop technological processes for the restoration of other working bodies of tillage machines by the method of vibration deformation.

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.
