The article investigates the stress-strain state of a thin-walled cylindrical pressure vessel with smoothly joined spherical heads operating under internal overpressure. The structural configuration of the sealed vessel, formed by sheet elements connected by longitudinal and circumferential leak-tight riveted joints, is considered, and a verification calculation of its main components is performed. The study generalizes contemporary approaches to the analysis of riveted joints with due regard to strength conditions, tightness, preload compressive forces, and the characteristic features of possible failure, which made it possible to substantiate the expediency of using such joints in critical pressure-loaded structures.
Based on the principles of strength of materials for thin-walled shells, the regularities of membrane stress distribution in the vessel walls were determined as a function of the shell geometry, wall thickness, and radii of curvature. It is shown that in the cylindrical part of the vessel, the stress in the longitudinal section is twice as high as that in the circumferential section; consequently, the longitudinal riveted joints are the most heavily loaded and should be regarded as the governing elements in calculations under internal pressure. A sequence for the verification calculation of riveted joints is presented, including the selection of the joint type, determination of the required wall thickness, evaluation of the joint efficiency coefficient, selection of the rivet diameter, and verification of the joint with respect to shear, bearing, and tightness.
Two possible design variants of this joint were considered, and it was established that the more rational solution is the one in which the cylindrical shell is arranged as an internal element relative to the head. Such a design promotes higher tightness of the circumferential joint, reduces the influence of local compressive forces in the transition zone, and improves the overall reliability of the structure. The obtained results can be used in the design, calculation, and improvement of sealed thin-walled pressure vessels operating under internal pressure.

Publisher Vinnytsia National Agrarian University
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 119 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Ihor Kupchuk, Candidate of Technical Sciences, Associate professor, Associate Professor of the Department of Engineering Mechanics and Technological Processes in the Agricultural Industry Faculty of Engineering and Technology Vinnytsia National Agrarian University 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.
