Annotation

Due to the growth of bulk cargo transportation by road, it is necessary to increase the level of mechanization and automation of loading and unloading operations. In recent years, various powerful high-performance unloading machines of original designs (car tippers, vibrating platforms, elevators, etc.) have been created to mechanize unloading processes. This makes it possible to speed up unloading, reduce costs and reduce excessive downtime of dump trucks under unloading. However, the use of such machines is cost-effective at unloading points with a turnover of more than 30 dump trucks per day.

Therefore, the problem of creating simple and cheap equipment that ensures efficient unloading of dump trucks with bulk cargo, as well as cleaning of rolling stock from cargo residues, as regardless of the type and composition of cargo, some of them are delayed on the floor, in stamped ribs. pockets of all-metal body walls. The largest amount of cargo remains on the hatch covers, the angle of which is on average 300, while the angle of the actual slope of the cargo reaches 450 and more.

Due to this ratio of angles, even dry material cannot fall out completely through the hatch opening, let alone moistened or viscous bulk cargoes. The amount of bulk cargo residues depends on many factors (type of cargo, its humidity, size of pieces, air temperature, distance of transportation, method of unloading) and can be from 2 to 30% of the total weight of the cargo [1]. The use of useful vibrations allows to solve this problem the most expediently. Therefore, the development of a vibratory shock device for unloading vehicles is a promising and urgent task.

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.
