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 Analysis of the influence of the inter-wheel differentials design on the resistance of the car curved motion(Технологический центр, 2019) Volontsevich, Dmitriy Olegovich; Mormylo, Jakov; Veretennikov, IevgeniiThe method and results of the analysis of the influence of the inter-wheel differentials design and the corresponding proportionality factors for the additional locking torque on the curved motion resistance of the four-wheel drive vehicle on paved roads are given. This allows choosing the most suitable designs for the parametric synthesis of the internally automated inter-wheel differential taking into account the results of studying the efficiency of different types of inter-wheel differentials under off-road conditions. Parametric optimization will allow synthesizing the internally automated inter-wheel differential, which would satisfy the requirements both to the vehicle cross-country ability and dynamics while not preventing the curved motion. In the process of modeling, the influence of the design and parameters of the inter-wheel differentials on power consumption in the motion with the given speed and trajectory, as well as on the actual turning radius of the vehicle, was estimated. According to the modeling results, it is concluded that it is possible to create a permanent internally automated inter-wheel differential based on differentials, in which locking degree depends on the squared difference in angular velocities of the semiaxles. For this, it is necessary to carry out optimization with respect to the proportionality factor of the locking torque, taking into account the limitations set forth in the work and using the described method of analyzing the influence of the inter-wheel differentials design on turning resistance. This will allow the effective operation of military and civil four-wheel drive vehicles both in difficult road conditions and on paved roads. In addition, the process of driving will not distract the driver to control the inter-wheel differentials, and the transmission will be performed without undue design complications.
