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 Evgenievich
The 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.
Automation of Analysis And Structural-Parametric Synthesis of Planetary Gearboxes With Two Degrees Of Freedom
(Austria, Sankt Lorenzen, 2016) Volontsevich, Dmitriy; Pasechnyi, S.
The planetary gears in transmissions of non-rail ground transport vehicles are widely used. Mostly, all modern automatic transmissions are based on the planetary mechanisms. The design of the optimal schematic diagram and the calculations of the parameters is extremely complicated. Moreover, this process is automated particularly. The design of kinematic schemes, which based on the selected linkages is the most complicated process for automatization. The algorithm and software for analysis and structural-parametric synthesis of planetary gearboxes with two degrees of freedoms is considered. The suggested approach can be applied to elementary planetary gears and systems with two or more satellites and double-wheel gears. The software is implemented only for planetary gearboxes with two degrees of freedom. The software for the planetary gearboxes with three degrees of freedom is implemented at the nearest time. The quantitative criteria of quality for estimation of planetary gearboxes quality are developed. These criteria allow to numerically evaluating the following characteristics of planetary gearboxes as the presence and magnitude of the circulating power, the relative magnitude of the torque on brakes and clutches, the relative speed of rotation of the central units, satellites and open-loop brakes and clutches and much more. The generated kinematics schemes are compared according to selected multiple criteria or integrated criteria with weights coefficients.
Modeling Curvilinear Motion of Tracked Vehicle with the Dual-Flux Electromechanical Turning Mechanism
(Austria, Sankt Lorenzen, 2016) Volontsevich, Dmitriy; Duong, Sy Hiep
Tens of thousands of old tracked vehicles with no ergonomic and ineffective the turning mechanisms are exploited in the world. Light multipurpose tracked transporter-tractor MTLB – is one of these machines, which is equipped with mechanical dual-flux turning mechanisms. These turning mechanisms are controlled by levers instead of a steering wheel and in the turning the part of the kinetic energy is converted to heat by friction mechanisms. This article analyzes the problems of the installation of electric drive in the mechanical dual-flux turning mechanisms of tracked vehicles. Previously, by the authors of this article were published materials, which by the analytical methods investigated the possibility of using the electric drive in the dual-flux turning mechanisms on the example of the light multipurpose tracked transporter-tractor MTLB. To solve this problem, the authors proposed an algorithm and a program that allow by numerical modeling techniques make the parametric optimization of the turning mechanisms and use them to assess their effectiveness. In contrast to the analytical determination of the trajectory of movement of the machine numerical simulation make possible to calculate trajectory considering real-slipping and skidding of caterpillar tracks. In the next publication is planned to bring the results of the comparative modeling of the entry process in the turning of light multipurpose tracked transporter-tractor MTLB with the standard mechanical and two selected scheme of the electromechanical dual-flux turning mechanisms.
