Annotation

The paper addresses the issues of increasing the durability of piston pins of automotive and tractor engines through the use of vibration oscillations during their restoration.
Experimentally found the optimal values of the angle of inclination of the machined tool – punch and its effect on the amount of metal sticking to the working surface of the punch, which reduces the quality of the processed surface of the piston pins and increases the non-uniformity of deformation in the radial direction and length.
The change of the residual strain along the outer and inner diameter of the piston pin during vibratory deformation is shown.
The obtained mathematical dependences of the change in residual strain on the outer diameter on the value of the allowance for processing.
Experimentally found a relationship that associates residual deformation with the wear of piston pins.
The results of the work will be used for the development of technological processes for the restoration of piston pins and bushings of the top heads of connecting rods of various autotractor engines by the method of vibration deformation.

Keywords: technological process, mechanical oscillations, sticking of the material, residual deformation, processing allowance.

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.
