Annotation

The paper considers the issues of increasing the reliability of agricultural machinery through the use of reinforcing processing of recovered machine parts by plastic deformation, which provides an increase in the quality of their surface layer during recovery.
The operational stability of the piston fingers and the upper heads of the connecting rods restored by vibration reinforcement on the engines working in the mechanized agricultural complex was carried out: tractor - agricultural machine - car. Studies have shown that the amount of wear of piston fingers restored by the vibration deformation method is 1.23 times smaller than the traditional method of recovery, which confirms the effectiveness of vibration technology.
Technological processes of restoration of discs of diggers of beet harvesters, discs of coulters of grain planers, plow blades with use of vibrating vibrations of the processing tool are developed and put into production.
The results of these developments showed an increase of 1.21 times the time of beet harvester harvesting with the diggers' wheels with the vibration-strengthened method; an increase in technical use factor of 1.07 times, compared to new 65G steel wheels.
To improve the reliability of the PLN-5-35, PLN-3-35 plows, the technology of restoration of working bodies - blades is developed and introduced into production, which provides for increase of their durability and durability.
The coefficient of technical use of the plow units with the blades restored by the developed technology is 1.01 times higher than that of the plow units with the new blades made of 65G steel.
The wear rate of the toe, width and thickness of the blade are 1.51 respectively; 1.22 and 1.27 times less than the new 65G steel blades.
The results of the study of vibrating reinforcing processing of working bodies of agricultural machinery help to increase their resource, which provides increased reliability of machines.

Keywords: working bodies, plastic deformation, vibration processing, reliability, coefficient of technical use, durability, durability.

History of journal:

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.
