ENSURING RELIABILITY AND RESOURCE CONSERVATION COULTERS DISCS OF GRAIN SEEDERS
Trukhanska Olena – Candidate of Technical Sciences, Associate Professor, Associate Professor of the Department of Agroengineering and Technical Service of Vinnytsia National Agrarian University (Solnechnaya St., 3, Vinnytsia, 21008, Ukraine, e-mail: seaswallow@ukr.net ).
Gadaichuk Maksym - engineer of the "Niva" farm.
A study was conducted aimed at studying the problems of the reliability of coulter discs and proposing ways, methods of restoring and optimizing the design of coulters of grain seed drills to maximize their reliability and durability.
Grain planters in agriculture play a key role in the process of growing crops. However, one of the most important components of these units are coulter discs, which are often exposed to aggressive conditions and heavy physical loads. Ensuring the reliability of coulter discs of grain seeders is a key aspect in agricultural production, since the efficiency of the technological process of sowing directly affects the yield and quality of agricultural crops.
A thorough analysis of the geometry and materials of the disks was carried out to identify weak points and potential sources of activation, as well as to determine the main factors that lead to their wear and destruction.
The values and distribution of the residual stresses in the material of the new disk and the restored one by welding three segments made of steel with surmite surfacing and vibration hardening were determined.
The values of the degree of strengthening of the material of the cutting edge of restored coulter discs were found. Optimal modes of vibration strengthening are established: frequencies and amplitudes of oscillations of the processing tool, time.
The research makes it possible to develop an optimized design of opener discs, which will ensure their high reliability and service life during various operating conditions.
The results of the research will be used to improve the technical characteristics and production technologies of coulter discs, which will help to increase productivity, reduce the costs of repairing seed drills and ensure efficient sowing.

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.
