Документ Comparative analysis of current approaches to digital twins of electro-hydraulic mechatronic systems creations(Hydraulics and Pneumatics Research Institute, Bucharest, Romania, 2023-11-10) Skvorchevsky, Alexander EvgenievichThe aim of this study is to identify approaches and principles for creating digital twins of electrohydraulic mechatronic systems. The aim of the study was achieved by bibliometric analysis and systematic review for identification approaches and principles of creating digital twins of various electro-hydraulic mechatronic systems in all stages of their life cycles. As a result of the research, publications were systematized in accordance with the approaches and methods proposed in them for creating digital twins of electrohydraulic mechatronic systems and their elements. Namely, which stages of the life cycles of electrohydraulic mechatronic systems are covered by the approaches and methods proposed in publications. During the bibliometric analysis, no publications were identified that would offer a systematic methodology for creating different types of digital twins of electrohydraulic mechatronic systems at all stages of their life cycles. Thus, the creation of such a systematic methodology is an important scientific and practical task.Документ The possibilities evaluation of replacing electro-hydraulic actuators with planetary roller screws linear actuators(Харківський національний автомобільно-дорожній університет, 2023-05-24) Skvorchevsky, Alexander EvgenievichFor decades, electromechanical and electrohydraulic actuators have competed with each other. Despite the significant advantages of electromechanical actuators, firstly the absence of possible oil leaks, and the conversion of electrical energy directly into mechanical energy, in many industries they could not compete with electro-hydraulic actuators due to the high-power density of the latter. Also, the advantages of electro-hydraulic actuators include the possibility of damping shocks and vibrations that occur in equipment and heavy-duty machines.Документ Restoration and transformation of high-tech machine building industry by implementing the principles of the CALS-concept in the context of Industry 4.0 development(ПП "Технологічний Центр", 2022) Volontsevich, Dmitriy; Skvorchevsky, Alexander EvgenievichThe object of this study was the processes of restoration and transformation of high-tech engineering using the principles of Industry 4.0 and CALS-concept. The problem of identifying ideas, concepts, tools and developing the principles of their application for the restoration and transformation of high-tech engineering has been solved. It is shown that the restoration of high-tech engineering, in countries affected by hostilities, is advisable to carry out using the CALS concept. The top priority CALS technology and systems have been identified. An opportunity to jump from Industry 2.0 to Industry 4.0. for countries in which mechanical engineering has suffered greatly as a result of hostilities has been shown. The principles of restoration and transformation of high-tech engineering by implementing the principles of CALS concept in the context of Industry 4.0 development have been developed. The infrastructure of the participants of the life cycle of machine-building products is proposed. A model for optimizing the production program of the defense-industrial complex has been built. The model takes into consideration the nonlinearity associated with the optimization of the production program, as well as the stochastic nature of changes in the model parameters. An adaptive approach is proposed that makes it possible to optimize the production program according to the model even for specialists without special mathematical training. The priorities of post-war reconstruction of high-tech engineering have been defined. This study will make it possible to transform and restore the machine-building industry destroyed as a result of hostilities as soon as possible. The condition for the practical use of this study is to stop the hostilities.Документ ELS capacity control system for axial-piston pumps(Національний технічний університет "Харківський політехнічний інститут", 2016) Skvorchevsky, Alexander EvgenievichДокумент Current state of open data ecosystem in Kharkiv region and Kharkіv city(Луцький національний технічний університет, 2019) Skvorchevsky, Alexander EvgenievichДокумент Innovative and military-industrial component of overcoming modern challenges of the Baltic-Black Sea region countries(Wyższej Szkoły Technicznej Katowice, 2019) Savchenko, Olga; Skvorchevsky, Alexander EvgenievichThe purpose of the study is to analyze the capabilities of the military-industrial resources of the Baltic-Black Sea region, the ways of their integration and the level of innovation, as one of the most important components of competitiveness in the global market for weapons and military equipment. Paper contributes to the state-of-the-art of open innovation in way explores of external knowledge used in the innovation process. Study the origin of external knowledge used in the innovation process.Документ The structural synthesis of elektrohydraulic mechatronic modules based on assignment problem(Вінницькій національний технічний університет, 2017) Skvorchevsky, Alexander EvgenievichДокумент Modern requirements for electrohydraulic drives of combat and civilian vehicles(Національний технічний університет України "Київський політехнічний інститут"; Механіко-машинобудівний інститут, 2016) Skvorchevsky, Alexander EvgenievichДокумент Econometric models robust estimation practical aspects(НТУ "ХПІ", 2016) Skvorchevsky, Alexander Evgenievich; Larka, S.
