DEVELOPING THE BEHAVIORAL PATTERN OF NON-RIGID INTERPIPE JUMPERS WITH COMPLEX CONFIGURATION AT A PIPE BOARD UNDER IMPULSE LOADING
Vakulenko Roman - Candidate of Technical Sciences, Associate Professor of the Department of industrial Engineering Mikhailo Ostrohradskyi Кremenchuk National University (St. University , 20, Кremenchuk, Ukraine, 39600, e-mail: rom.vak311@gmail.com).
The article deals with the simple two-dimensional axis-symmetric mechanical model of the technological system of the operation to distribute a steel pipe into a steel pipe grid is considered. The pipe grids are replaced by an equivalent bushing having a height H and radii of the inner and outer surfaces R1 and R2, respectively. The calculation was made for the most commonly used metal pair. The steel pipe and pipe grid are assumed to deform according to the elastoplastic type. The pipe material steel type 12X18H9T Material of the pipe board steel type 40X. From the inside, the pipe is subjected to impulsive pressure, being not uniform in length and time.The pressure amplitude during pulsed flaring and explosion welding of pipes with pipe grids is given. For solution under the Wilkins method, the pipe was divided into quadrilateral elements. In the radial direction 6 rows of elements were used, in the axial direction – 400 rows, and there totally were 2400 elements used for the pipe. The bushing is divided into 23 rows in the radial direction and 100 rows of elements in the axial direction, with totally 2300 elements. Further, the deformed state was analyzed at a number of characteristic points located on the pipe outer surface and the bushing inner surface. The graph shows the radial displacements of points on the pipe surface in the initial period of time. The non-simultaneity of the collisions and the out-of-phase oscillations indicate bending and bending vibrations of the pipe. The dependence of the node displacements on the bushing inner surface in the radial direction on the deformation time and the dependence of the point radial velocity on the outer contact surface of the pipe on the deformation time are also shown. The dependence of the displacement speed of the points of the nodes located on the sleeve surface on time in the initial period of the process is given. The stressed condition of the system elements is characterized by the occurrence of stress waves generated by pipe being struck and spreading in the bushing and pipe. The process of pipe fastening is analyzed using the model of a flat deformed state. The co-deformation of a pipe and a pipe board with a hexagonal hole arrangement is considered for the case if a single pipe needs flaring inside the pipe grid.

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.
