Annotation

Principles of construction and research of deterministic models of vibration and vibro-impact machines are considered. The general analysis of work on vibration and vibro-impact compression allows to distinguish the signs of the corresponding modes of work on the basis of mathematical models of working processes of vibrating and vibro-impact machines.

The design of the inertial vibropress-hammer model and the description of its parameters gives the opportunity to choose different modes of inertial loading during the process of working out the technological processes of forming the pieces of powdered materials by the method of vibro-impact compression, allowing to evaluate the efficiency of their application.

The operating mode of inertial vibration press-hammer in the process of vibro-impact compression is characterized by an aggregate of mechanical parameters of transient processes occurring in the working liquid of the hydropulse drive and in the interaction of mobile units of the IVPM as a result of the periodic activation of the vibration exciter.

 

Keywords: vibration machines, vibro-impact machines, hydraulic drive, efficiency, working modes of pressing, vibro-impact presses

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.
