Публікація Justification of the parameters of the active conical wood deformer(2025) Падалка, Вячеслав Вікторович; Padalka, V. V.; Горбенко, Олександр Вікторович; Gorbenko, O. V.; Іванкова, Олена Володимирівна; Ivankova, O. V.; Дудник, Володимир Васильович; Dudnyk, V. V.; Горюнов, Богдан Олегович; Horiunov, B. O.The object of research is the parameters of mechanisms for the destruction of anisotropic materials by a conical mechanical deformer. One of the known renewable energy sources is a material of plant origin (wood). Based on this, the search for optimal operating parameters and design features of working bodies for mechanized splitting of logs is relevant. Therefore, a new solution to the scientific problem is proposed, which consists in substantiating the main geometric parameters of an active conical deformer for splitting logs from wood at the lowest energy costs for its drive. The analysis conducted during the study showed a general positive feature of the principle of operation, in which the penetration of an active deformer of a conical shape perpendicular to wood fibers facilitates the destruction of their ties and has a more promising and productive design. A mathematical model for determining the force required to destroy a log of wood has been developed. The specified dependence takes into account the elastic characteristics of the material, the forces that exist between the fibers of anisotropic substance, the friction forces between the deformer material and wood, and its geometric parameters. It was determined that the necessary value that characterizes the physical and mechanical properties of wood is the force required to destroy the bonds between the fibers (coefficient of longitudinal destruction). Therefore, the values of the coefficient of longitudinal destruction were experimentally obtained, which were for pine – 2533 ± 66 N/m, oak – 5583 ± 145 N/m and aspen – 5000 ± 279 N/m. According to the research results, analytical recommendations for the geometric parameters of the active deformer were obtained. For pine material with a diameter of 0.15 m, the optimal cone length is in the range of 0.02–0.20 m at a cone angle of 20–90°. At the same time, the theoretical force for its destruction is 568–864 N. Similar results were also obtained for aspen and oak materials. This provides the opportunity to design the design of a conical wood deformer according to the specified ranges, which are optimal for each material or their groups.Публікація Determination on energy efficiency in corn grain drying(2025) Горбенко, Олександр Вікторович; Gorbenko, O. V.; Лапенко, Григорій Олександрович; Lapenko, G. O.; Лапенко, Тарас Григорович; Lapenko, T. G.; Kolotii, S.The object of research is the technological processes of corn grain drying, energy plants. One of the most problematic areas for agri cultural producers is providing energy for technological processes of bringing grain material to the indicators of product sales. And during the war and post-war period in Ukraine, this requires non-standard approaches and ways of implementation. Therefore, for operation in autonomous mode, the technology involves the use of biomass, electricity from solar panels and/or a diesel generator to supply the coolant to the grain drying zone. The availability of biomass is ensured by cleaning grain material after harvesting and crop residues. The study examined the technology of corn grain drying in "Agrotechservice" LLC of the Poltava district of the Poltava region (Ukraine) using the Saphir 2134 modular grain dryer with an improved biomass boiler. The results of studies of the operation of a grain dryer using different types of fuel (gas, diesel fuel, alternative fuel) showed that the energy consumption for reducing humidity by 1 ton-percent was: for gas – 1.5 m3; for diesel fuel – 1.8 l; for biomass – 3.4 kg. The total cost of drying on a Saphir 2134 grain dryer was obtained, which is 0.205 USD, which is 3.7 times less than when using natural gas and 9.2 times less than when using diesel fuel. This is due to the fact that the proposed technology involves the use of an improved biomass boiler and alternative energy sources. This provides the possibility of obtaining average daily savings using a grain dryer of this model with an improved biomass boiler, which will be about 1.1 thousand USD. Compared to similar corn grain drying processes, these studies have shown the economic feasibility of using biomass as an energy material for the production of thermal energy in the corn grain drying process.Публікація Construction of a theoretical model of oscillations of a tillage (seeding) implement with independent mounting and two support rollers(2026-09-10) Падалка, Вячеслав Вікторович; Padalka, V. V.; Горбенко, Олександр Вікторович; Gorbenko, O. V.; Khvostenko, D.; Лазоренко, Андрій Ігорович; Lazorenko, A. I.; Alpidovskyi, V.This study investigates natural harmonic vibrations of a working implement equipped with a lever-type hitching system to the traction mechanisms and two support points on the surface. The task addressed relates to the absence of a generalized theoretical model for quantitative prediction of amplitude-frequency characteristics of such systems. This complicates the substantiation of rational structural and geometric parameters to enable technologically acceptable vertical deviations of working bodies under field irregularities and variable soil properties. A calculation scheme of a two-support lever mechanism has been devised, separating the implement’s intrinsic dynamics from the power unit motion and considering roller-soil contact as an excitation source. An energy-based mathematical model using Lagrange equations of the second kind has been constructed; parametric modeling revealed the decisive influence of attachment geometry and made it possible to determine rational parameter values. The length of the hitch lever to the power unit is 0.5 m, and the distance from the oscillatory system’s center of mass to the hitch point is 0.25 m. The advantage of the results involves the analytical relationship between the mechanism geometry, contact parameters, and vibration characteristics, which enables structural minimization of vertical deviations without mandatory use of active control. The identified regularities are explained by changes in the reduced inertial-elastic characteristics of the system when varying the lever arms and the position of the hitch point relative to the center of mass. The results could be practically applied at the stages of designing and adjusting implements provided that equivalent elastic-damping parameters of the" roller-soil" contact are identified for specific field and soil conditions and operating speeds.Публікація Дослідження технологій відновлення деталей агрегатів гідросистеми сільськогосподарської техніки(2025) Іванкова, Олена Володимирівна; Чумак, М.; Федін, В.Не існує сільськогосподарської техніки, яка могла б працювала вічно.

Yu.; Прілєпо, Наталія Володимирівна; Priliepo, N. V.; Басова, Юлія Олександрівна; Basova, Yu. O.; Honcharenko, O.; Zakharov, A.The object of this research is the casting technology of double-layer rolls for universal beam mills (UBM). They are critically important components of the metallurgical industry, ensuring the production of beams, profiles, and other structural elements, widely used in construction, mechanical engineering, transport, energy, and other industries. Developing innovative approaches to manufacturing rolls is strategically important for strengthening Ukraine's production potential. Since one of the most problematic areas is the dependence on imported rolls, which leads to significant economic losses, logistical risks and restrictions on the country's technological independence. Existing domestic technologies do not always lead to achieving the necessary operational characteristics, such as wear and heat resistance, and durability, complicating the competitiveness of products on the international market. The work proposes an innovative technology for manufacturing two-layer rolls, using stationary casting molds, a bainite-martensitic outer layer structure, and optimization of temperature conditions. This provides high hardness, heat resistance, and wear resistance of the outer layer. The inner layer, made of high-plasticity materials, compensates for residual stresses and improves structural stability. The use of alloying elements (nickel, molybdenum, copper) in combination with mathematical modelling of temperature fields made it possible to reduce the number of structural defects, such as porosity and delamination while ensuring uniform connection of the layers. This is because the proposed technology combines modern approaches to alloying, heat treatment optimization, and high-tech modelling of temperature conditions during casting. A notable characteristic is the optimization of materials to withstand elevated mechanical and thermal stresses, complemented by an advanced casting mold design that enhances interlayer adhesion and minimizes the likelihood of defects. This facilitates the reliable performance of rolls under challenging operational conditions, characterized by elevated mechanical and thermal stresses. Compared with similar known solutions, the proposed technology increases the service life of rolls by 20–25 %, reduces repair and maintenance costs by 15–20 %, and increases the efficiency of production processes by reducing the frequency of equipment shutdowns.Публікація Determination of analytical dependencies of distributed forces in a deformable wheel – deformable surface contact zone(2025) Ковбаса, Володимир Петрович; Kovbasa, V. P.; Прілєпо, Наталія Володимирівна; Priliepo, N. V.The object of this study is the contact interaction of two deformable bodies of inconsistent geometric shape, in particular, change in the stress-strain state of the wheel and the supporting surface. The significance of this topic arises from growing demands for vehicle mobility in difficult terrains, the necessity of minimizing environmental impact, and the need to optimize the design of mobile machinery components. A major challenge lies in developing a suitable analytical solution to define the stress-strain state variations within the contact zone between the wheel and soil or other surfaces. This study employs an approach grounded in the fundamental principles of mathematical physics applied to elasticity theory problems. This enabled the derivation of analytical equations that describe the absolute deformations of both the surface and the wheel (tire), along with the contact pressure distribution. The pressure distribution within the contact zone was determined using the properties of surface integrals of the second kind. Concentrated forces, when related to the contact area, were equated to the integral value of this surface integral. The values of these distributed forces were then incorporated into the transformed Boussinesq and Cerruti potential equations. The resulting analytical relationships can be utilized to determine the relative deformations of the contacting bodies and the stress distribution within them. Crucially, these relationships also serve as a basis for deriving equations that define the contact zone boundaries and the rolling resistance coefficient for deformable bodies. These derived relationships are general and presented in a form applicable to loads on both driving and passive (driven) wheels. This proposed model offers substantially improved analytical accuracy over existing empirical methods. Moreover, these analytical dependencies help circumvent the computationally intensive calculations typically required by FEM (Finite Element Method) or DEM (Discrete Element Method) simulations for every unique loading scenario and material property set.Публікація Analytical determination of absolute deformations and boundaries of the contact zone of a deformable wheel with a deformable surface(2025) Ковбаса, Володимир Петрович; Kovbasa, V. P.; Прілєпо, Наталія Володимирівна; Priliepo, N. V.The object of research is the contact interaction between a deformable wheel (tire) and a deformable supporting surface. One of the most problematic areas is defining the boundaries of the contact zone as a function of applied loads, wheel geometry, and the mechanical properties of the contacting surfaces, as well as the increasing need to reduce energy consumption and soil compaction in the context of vehicle running gear systems. During the research, methods from the mechanics of continuous deformable media were used to identify the deformable properties of contacting surfaces. The investigations were founded on previously published research concerning the distribution of contact forces, obtained using biharmonic potential analytical functions based on methods employed by Boussinesq and Cerruti. Analytical dependencies have been derived that relate the leading and trailing edges of the deformable wheel's (tire's) contact with the deformable surface. This is because the proposed approach, which considers the relationship between forces and displacements on the surface and deformations and stresses within the contacting bodies, taking into account their mechanical properties, is more informative compared to methods of theoretical and analytical mechanics. The research revealed that the potential for improving the object's functioning lies in optimizing the selection of parameters and operating modes for running gear systems. Thanks to this, it becomes possible to obtain optimized values for the geometric size of the contact surface. Compared to analogous known approaches, this ensures an enhancement in the tractive efficiency of driving wheels, minimizing wheel slip to acceptable levels, which directly addresses key challenges in agricultural and off-road machinery by contributing to reduced energy consumption and soil compaction.Публікація Research on dynamic impacts on geological environment, soil foundations, and structures(2026-07-13) Mykhailovska, O.; Біда, Сергій Васильович; Bida, S. V.The article analyses the primary methods for determining dynamic characteristics. It has been established that the real environment in which the dynamic processes of seismicexplosive wave propagation occur is not described by an ideal model and is very difficult to describe with equations. The vibration acceleration resulting from the seismic action of explosions in quarry mining and processing plants has been calculated. It has been determined that the calculation can be performed using analytical methods and the finite element method (error of about 4%). It has been established that the application of the finite element method to calculate vibration acceleration during blasting operations in quarries enables the desired value to be calculated at any point of the object under study with reduced working time.Публікація Protection of the state geosite – “Pyvykha” mountain under the conditions of the development of sliding processes(2025) Біда, Сергій Васильович; Bida, S. V.; Zotsenko, M. L.; Pavelieva, A. K.; Lapin, M. I.To preserve the state geosite – Pyvykha Mountain, the authors have developed a set of measures to strengthen the landslide slope. However, the work is complicated by the possibility of rockslides and rock collapses, which threatens the equipment and people carrying out strengthening of the shore. After a detailed analysis and generalization of the results of the engineering and geological surveys conducted in this area, the most landslide-hazard zones of the slopes were selected and the stress-strain state of the slope was studied with the help of the Plaxis software complex, considering the possibility of a landslide. According to the simulation results, dangerous zones have been determined within which soil collapses are possible. It was concluded that the presence of people and equipment in these areas should be limited as much as possible.Публікація Formation of United Territorial Communities Based on the Principle of Urban Agglomerations(2022) Tatarchenko, H.; Biloshytska, N.; Biloshytskyi, M.; Shparber, M.; Біда, Сергій Васильович; Bida, S. V.The paper analyses factors, properties, and criteria contributing to the formation and development of the territorial community based on the principles of urban agglomerations in modern conditions on the example of cities in Luhansk oblast. In the modern world, it is no longer a question of competition between countries but actually between cities–agglomerations or metropolitan cities. In fact, they have been in Ukraine, e.g., large cities of Kyiv, Kharkiv, Lviv. Currently, Ukraine has introduced three levels of the administrative-territorial system, which distinguish the following units: community, district, region. As a part of the decentralization reform in Ukraine, 490 old districts have already been liquidated and 136 new ones have been formed. There have been created 1470 united territorial communities, which should become the basis of local self-government. A criterion analysis of the territory with adjacent settlements has been conducted from the point of view of unification into a territorial community. Priority measures for the development and improvement of the united territorial community as an urban agglomeration have been proposed. Based on the criterion analysis of ‘Severodonetsk-Lysychansk-Rubizhne’ territory with adjacent settlements, we can consider the united territorial community as an urban agglomeration, and develop it as a complex system that includes not only cities and settlements around them, but also all production facilities, resettlement of inhabitants, interaction of nature and urban population as a single entity. For such agglomerations, emphasis should be placed on spatial development, in particular on traditional distribution factors, such as transport, material, labour costs.Публікація Deformation Monitoring of Silos on the Basement, Reinforced with Soil–Cement Elements, Manufactured According to Boring and Mixing Technology(2022) Біда, Сергій Васильович; Bida, S. V.; Marusych, O.; Zotsenko, M.; Pavelieva, A.The construction of a significant number of new facilities takes place on the territories, where geological-engineering conditions are complicated by the pres ence of man-made soils or soils with special properties, which makes it necessary to reinforce the basement. This problem becomes particularly topical in construc tion of such structures as grain storage silos that transfer significant loads to the basement. One of the options for reinforcement is the installation of soil–cement elements, manufactured according to boring and mixing technology. Reinforcement of the basement in this way is quite effective due to the applicability of elements of different diameters and lengths, as well as through adequate choice of distance between them. Variation of these parameters allows to perform reinforcement almost in any geological conditions, taking into account the possibility of consolidation of the bases and foundations below the water table. However, designing and operation of the structures, standing on basements, reinforced in this way, requires intensive study of the stress–strain state of the system “foundation bed–reinforced basement”, taking into account operational features of such structures. Proper allowance must be made for different degrees of silos loading and cyclic loading and unloading. Investigative research of the deformability of such systems is possible by applying various models of soils and the finite-element method as a mathematical apparatus. When choosing a model, consideration must be given to such factors as the accu racy of behavioral model of foundation soils and the simplicity of identification of parameters, required for performing calculations. Special attention should also be given to monitoring the development of subsidence of the structures, built on the reinforced basement, taking into account the time factor for comparison with the results obtained analytically.Публікація Determination of the efficiency of shot blasting of metal surfaces(2025) Горик, Олексій Володимирович; Goryk, O. V.; Брикун, Олександр Миколайович; Brykun, O. M.; Kalashnykov, O.; Buchynskyi, A.The object of this research is the process of transformation of kinetic energy of the attacking air-abrasive torch in the process of dynamic impact on metal surfaces of products during their shot blasting. The importance of the research is due to the need to solve the problem of increasing the efficiency of the technological process of preparing metal surfaces of products by shot blasting for the subsequent application of protective, stable non-metallic coatings. In the work, based on the energy balance of the "shot-obstacle" system, a method for determining the efficiency coefficient of the shot blasting surface preparation process was developed, which was associated with the torch energy recovery coefficient. The relationship of the coefficients with the potential energy of the surface layer accumulated in the process of elastic deformation was established. The depth of the hole formed by the shot on the surface of the attacked body was taken as a measure of this energy. When determining the depth of the hole, the deformation of an elementary cylindrical element clamped in the surface layer of the attacked body was considered, the dimensions of which are compatible with the dimensions of the elastic deformation hole. The classical recovery coefficient is not a characteristic criterion for revealing the physical aspects of the complex multifactorial shot blasting process. The ease of application in practical calculations, especially when establishing the productivity of the process, prompts the search for improving the methods of its determination, since the existing models of an ideal impact in this case are not capable. This coefficient at average attack speeds of 100–120 m/s and angles of 40° < α < 70° turned out to be 15–20% less than the classical one. The obtained research results can be used to increase the productivity of the shot blasting process of products of the defense, agricul tural, machine-building, chemical, aviation and other industries.Публікація A mechanized assembly for erecting soil-cement barriers to protect agricultural lands from low-active waste during flood(2024) Петраш, Олександр Васильович; Petrash, O. V.; Zotsenko, V.; Петраш, Руслан Васильович; Petrash, R. V.; Попович, Наталія Миколаївна; Popovych, N. M.; Рожко, Ілона Іванівна; Rozhko, I. I.; Danova, K.; Malysheva, V.; Nikitchenko, O.; Nikitchenko, O.; Moroz, M.; Bogatov, O.The object of this study is the process of constructing a waterproof underground barrier from local soil using loess loam and medium-sized sand as an example. The values of waterproofing of soil cements on different types of soil and the norms of net labor consumption corresponding to them were obtained. The research solves the task of protecting agricultural lands in the areas of geological burials of low-level radioactive waste. Configuration of a mechanized drilling mixing assembly for installing a waterproof barrier in the field has been proposed. Waterproofness of soil cement on clay and sandy soils was determined experimentally. The corresponding norms of the net consumption of time for manufacturing the barrier in these soils have been determined. Units of the mechanized assembly are repairable, utilize widely available materials, parts, and mechanisms. As a result of studies on the labor intensity of the installation of soil cement, a net labor rate was established, which varies from 35 to 52 min/m3 depending on the type of soil. The corresponding values of waterproofness, which ranged from W6 to W14, were determined, which substantiates the possibility of effective functioning of soil-cement underground barriers. Options for the structural solution for impenetrable barriers have been offered. The values of the obtained net time rates are explained by the high degree of mechanization of the technological process and the use of local materials. A distinctive feature of the results is the emphasis on the data collection on the time consumption of machines and mechanisms, the characteristics of local soils under production conditions, and the use of local materials. The assembly implies using affordable and repairable units that can be serviced right in the field. Given this, the manufacturability of the proposed process was defined, confirmed by time-keeping studies. The realm of practical application of the reported results are sites within flat areas with sandy or loess bases. Barrier solutions are designed exclusively for geological waste storage facilities under the conditions of a high level of groundwater and the presence of a waterproof layer at the base.Публікація Results of determining the influence of moisture content on the flow of substances in meat under the combined action of heat flow and electric current(2024) Скрипник, Вячеслав Олександрович; Skrypnyk, V.

O.; Бичков, Ярослав Михайлович; Bychkov, Ya. M.; Bychkov, Y.; Харак, Руслан Миколайович; Kharak, R. M.The paper addresses the implementation of vacuum switching devices in combination with digital monitoring and diagnostic systems as an integral component of modern high-voltage electrical networks. Particular attention is focused on the analysis of electrophysical switching processes in a vacuum environment, the structural features of contact assemblies, and the possibilities for integrating circuit breakers into hierarchical control systems in accordance with the Smart Grid concept. The principles of vacuum arc operation, the characteristics of dielectric strength recovery in the inter-contact gap, and the influence of contact materials on the stability of switching regimes are summarized. The architecture of modern monitoring systems based on the IEC 61850 standard is considered, including the use of electrical and thermal sensors, microprocessor-based controllers, and integration at the SCADA/industrial automation level. It is shown that the combination of vacuum circuit breakers with digital control tools ensures a reduction in fault localization time, an increase in equipment availability, and a decrease in operational risks. A generalized structural model of the “vacuum circuit breaker – digital control” system is proposed, suitable for application in 6–35 kV networks and, prospectively, in substations of the 110–220 kV class.Публікація Conductive frying of meat:current state and prospects(2025-12-18) Скрипник, Вячеслав Олександрович; Skrypnyk, V.
