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.

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.

The article presents the results of research and development of an energy-efficient biomass-fired boiler designed for grain drying using locally available types of biomass as an alternative energy source. The relevance of implementing bioenergy technologies in agricultural production is substantiated, taking into account the rising cost of fossil fuels and the growing need for environmental sustainability in the agrarian sector. A comparative analysis of modern grain dryers has been conducted, highlighting their design features, advantages, and limitations in the context of biomass utilization. A boiler design has been developed, incorporating a two-section tubular recuperative heat exchanger, an automated fuel feeding system, and a multi-stage fan-driven air circulation mechanism. A distinctive feature of the proposed model is the use of high-temperature-resistant AISI 310S stainless steel in the combustion chamber, which ensures increased resistance to thermal stress, slag formation, and soot buildup. An air recirculation system for the drying chamber is also proposed to enhance the overall energy efficiency. Based on the proposed design, experimental thermal modeling was carried out. The results were generalized as temperature dependencies under various biomass feed rates. The obtained graphs and tabulated data confirm the system's predictable response to parameter changes, which is critical for automated process control and achieving high-quality grain treatment. Mathematical modeling of thermal regimes confirmed a high degree of correlation (R = 0.95) between the biomass feed rate and the temperature of air supplied to the dryer, as well as operational stability across a wide load range. The findings indicate that implementing such a boiler in agricultural practice can significantly reduce energy consumption, lower harmful emissions, and improve the autonomy of farming enterprises. The proposed technical solution offers a promising direction for modernizing grain drying equipment under current agricultural production conditions.
Effect of vibration treatment on increasing the durability of tillage equipment working bodies
(Eastern-European Journal of Enterprise Technologies, 2021-04-20) Dudnikov, A. A.; Ivankova, O. V. ; Gorbenko, O. V. ; Kelemesh, A. O. ; Дудніков, Анатолій Андрійович; Горбенко, Олександр Вікторович; Келемеш, Антон Олександрович; Іванкова, Олена Володимирівна
This paper reports a study into the durability of tillage equipment working bodies. It has been established that the quality of surface layers during plastic deformation depends on a series of factors. These factors include the degree of hardening, the thickness of the hardened layer, the size and nature of the distribution of residual stresses. The study has shown that the technology to restore working bodies that involves vibration oscillations provides for higher durability. Investigation of deformed samples demonstrates that when exposed to vibration treatment, the microstructure is more fine-grained and even; the hardness of the treated surface of a ploughshare blade increases by 22‒35 %. This contributes to hardening the machined surface. It has been established that the tillage equipment working body wear is a random process, which is predetermined by changes in the structural dimensions and shape of cutting elements. An analysis of the wear distribution density of cutting elements has revealed its compliance with the law of normal distribution. It should be noted that the most influential geometric parameter of a working body affecting the part’s resource is the wear depth. This parameter determines the residual thickness of the ploughshare wall. Data from surface-layer studies at hardening make it possible to note a decrease in the limiting state of the examined parameters. In particular, the wear of a ploughshare tip was 17 % less than the limiting state. The study of durability has shown that the amount of tillage equipment working body wear is 1.28 times less when using vibrational plastic deformation. Accordingly, when restoring ploughshares, in order to increase the working bodies’ resource, it is more expedient to use a method that implies the welding of tires made from steel 45 involving sormite surfacing and vibration treatment.
Improving the technological process of restoring the tillage machine working parts
(Eastern-European Journal of Enterprise Technologies, 2020-04-30) Dudnikov, A. A.; Gorbenko, O. V. ; Kelemesh, A. O. ; Drozhchana, O. U. ; Дудніков, Анатолій Андрійович; Горбенко, Олександр Вікторович; Келемеш, Антон Олександрович; Дрожчана, Ольга Урешівна
An analysis of the wear of machine parts has made it possible to establish characteristic requirements for the technological process of restoring worn surfaces. Experimental studies on hardening the working surfaces of plowshares have made it possible to determine processing parameters: oscillation frequency of the processing tool of 1,400 min-1, the oscillation amplitude of 0.5 mm and processing time of 20 s. Studies of the influence of conventional and vibration working on strength characteristics were carried out first on models and then on actual parts. New shares served as models. Experimental studies of these shares provided the identity of the nature of the cutting element wear. The sameness of the model and the actual part deformation degree was provided by the same conditions of the passage of the hardening processes. The trustworthiness of the results of experimental studies was assessed in accordance with the law of theoretical distribution at a given value of confidence probability α=0.95. The studies have established that the share width of 116–117.5 mm which has a certain effect on the share efficiency corresponds to the highest probability of 0.39. It has been experimentally established that the degree of hardening of the shares made of L-53 steel and surfaced with sormite and vibration hardened is 1.85 times greater than in conventional processing. The studies have made it possible to determine the nature of change in the share shape and thickness of the cutting edge and choose a more efficient process of its restoration by vibration hardening. A method of recovering shares by welding strips of 45 steel with automatic hard surfacing and vibration hardening was proposed.

Interchangeability and maintainability of electric vehicles in the context of industry development
(2025) Горбенко, Олександр Вікторович; Gorbenko, O. V.; Лазоренко, Андрій Ігорович; Lazorenko, A. I.
The rapid growth of the global electric vehicle (EV) market is accompanied by a low level of interchangeability and maintainability of key components, leading to increased maintenance costs, dependence on authorized service centers, and challenges in battery recycling. The absence of unified design standards limits the possibilities for component reuse and creates technical barriers to the development of an efficient service infrastructure. Goal. To analyze the current state of interchangeability and maintainability of electric vehicles, identify technical, economic, and regulatory constraints, and develop recommendations for standardization and unification of design solutions aimed at improving the economic and environmental efficiency of EV operation. Methodology. The study employs a comparative analysis of EV designs from different manufacturers, a review of international standards (ISO 15118, CCS Combo, IEC 61851, SAE J1772), and systematization of service-related barriers. Economic risks associated with full-unit replacement and environmental consequences of limited battery recycling were assessed. Serviceability challenges and critical cost factors were analyzed using TCO (Total Cost of Ownership) indicators. Results. It has been revealed that most EV components have unique design parameters, preventing the use of universal spare parts and increasing TCO by 20–40%. A set of technical, economic, and regulatory measures is proposed, including modular architecture, dimensional interface unification, and the implementation of open diagnostic protocols. These solutions are expected to improve service accessibility and reduce vehicle downtime. Originality. Unlike existing studies, this paper integrates technical, economic, and serviceability aspects by proposing a structured scheme for standardizing EV components at technological, service, and environmental levels. A novel approach to evaluating maintainability is offered through indicators of modularity, compatibility, and availability of certified spare parts. Practical value. The findings can be used for the development of regulatory frameworks in the field of electric transport, the design of modular battery and power electronics systems, the creation of a market for certified component analogs, and the implementation of battery reuse programs. The proposed solutions contribute to reducing maintenance costs, extending vehicle lifespan, and minimizing environmental impact.
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.
Mechatronic colorimetric system for measuring operational degradation of engine oil as a means to enhance the reliability of motor vehicles
(2025) Падалка, Вячеслав Вікторович; Padalka, V. V.; Горбенко, Олександр Вікторович; Gorbenko, O. V.; Іванов, Олег Миколайович; Ivanov, O. M.; Chumak, M.
The article presents the results of a study on the operational degradation of engine oil under the working conditions of internal combustion engines (ICE) used in agricultural and automotive machinery, where the operating environment is classified as particularly severe: high air dustiness, irregular loads, frequent engine starts, and extended idling periods. These factors accelerate the wear of friction pairs, deteriorate lubricating properties, and reduce the overall reliability of power units. Existing maintenance regulations do not consider real operating conditions, which creates the need for inter-schedule monitoring of oil condition – possible only through technical measurements and digital analysis of degradation parameters. The aim of the research is to develop a methodology and conduct experiments to determine the resource indicators of engine oil based on color change using colorimetric equipment equipped with mechatronic system elements. The study is based on comparing the color of fresh oil with that of oil after operational wear. RGB/HSL colorimetry tools and statistical processing were applied. A laboratory setup was developed based on the STM32H747XI microcontroller and the TCS3472 color sensor, enabling the detection of oil color changes and evaluation of its degradation linked to engine operating hours. Calibration was performed between reference samples and boundary conditions corresponding to the full service interval. The investigation of VAG Special G 5W-40 engine oil (BSE engine) over 400 engine hours demonstrated a stable functional dependence between impurity saturation and engine runtime. The average increase in contamination confirmed a reliable correlation between color variation and actual wear of friction components. The proposed methodology enables inter-schedule monitoring of engine oil condition and prediction of optimal replacement timing based on real operating conditions. The practical significance of the study lies in the increased reliability of ICE, reduced maintenance costs, and prevention of premature equipment failures. The proposed mechatronic colorimetric system can be integrated into service centers and precision farming systems as a component of digital diagnostics of machine technical condition.

The trees (e.g., fruit or decorative) growing on the homestead plots of private households provide opportunities for sustainable biomass obtained from pruned branches every year. Profitable production of fuel material requires high-performance equipment and methods by which wood chips can be produced at low cost. The practice of chopping tree branches shows that not all chopping machines are suitable for use on homestead plots. This research gives the five-year test results of a developed and patented tree branch chopping machine under special operating conditions. The machine was tested under the conditions of the homestead plot of a private household in the Poltava region, and the engineering parameters to set up the chopper were determined. It is recommended to set a 0.3404 radian (19 degrees 50 min) angle on the chopper to cut tree branches as well as to set the size of the cutting knives’ protrusion above the disc plane within 0.0120 m. As a result of the correct settings, the power consumption of the chopper motor will be W = 1.3549 kW, which is an optimal value for the studied chopper. The research results made it possible to provide instructions for the tree branch chopper’s operation and to adapt it to the conditions of homestead plots.

(2025) Chaika, T.; Короткова, Ірина Валентинівна; Korotkova, I. V.; Шевніков, Микола Янаєвич; Shevnikov, M. Ya.; Ляшенко, Віктор Васильович; Liashenko, V. V.; Горбенко, Олександр Вікторович; Gorbenko, O. V.; Horbenko, O.
Soybean is one of the most in-demand crops, with its production increasing; however, climate change affects yield, necessitating the application of biopreparations to enhance plant resilience to stress conditions. This study aimed to investigate the effects of pre-sowing seed treatment with an inoculant and a phytohormonal preparation on the physiological and biochemical parameters of soybean plants and their yield under organic farming conditions. A field study conducted in 2022-2024 examined the impact of pre-sowing seed treatment with the inoculant Legume Fix and the phytohormonal preparation Violar on leaf area, proline content, malondialdehyde levels, photosynthetic pigments, and yield under various weather conditions in an organic farming system. It was established that pre-sowing seed treatment increased leaf area by an average of 13.4% with Legume Fix and by 19.3% with Violar. It was established that the highest increase in proline content (as a protective response) was observed in the hot conditions of 2024, with seed treatment using Violar (41.2%) and Legume Fix (26.5%). Over the study period, the lowest MDA concentrations in soybean plants were recorded following seed treatment with Violar and Legume Fix, averaging 7.57 and 9.33 µg/g fresh weight, respectively, which was 37.4% and 22.9% lower than in the control plants. Treatment with Violar resulted in an increase in Chl a, Chl b, and total Chl (a + b) content by an average of 18.9%, 13.3%, and 17.2%, respectively, compared to the control, while inoculation with Legume Fix led to increases of 7.4%, 3.4%, and 6.2%, respectively. Pre-sowing seed treatment with Legume Fix and Violar resulted in a higher yield than the control plants, with average increases of 13.2% and 20.6%, respectively. The obtained results may be recommended for organic farming to enhance crop yield.
Substantiating the rational parameters and operation modes for the hemp seed centrifugal dehuller
(2024) Шейченко, Віктор Олександрович; Sheichenko, V. O.; Petrachenko, D.; Koropchenko, S.; Rogovskii, I.; Горбенко, Олександр Вікторович; Gorbenko, O. V.; Volianskyi, M.; Sheichenko, D.
The object of research is technological processes, seeds of industrial hemp, and working bodies of the dehuller. A centrifugal-type device for crushing hemp seeds with a closed sector-type working body has been designed. Owing to this, the task related to seed dehulling was solved with a high level of efficiency in separating the seed coat from the kernel. The rational parameters for the dehuller have been substantiated: the diameter of the impeller is 162 mm, the gap between the impeller and the seed repelling panel is 80 mm, the frequency of rotation of the impeller is 2000 min–1. It was established that with the specified parameters and moisture content of the seeds within the limits of conditional (12.0–13.0 %), it is advisable to carry out dehulling process without preliminary separation of the seeds into fractions by width. It was established that an increase in seed size leads to a corresponding increase in the weight share of seed kernels. About 58.2 % of the main mass of seeds is the average fraction with a width of 2.5 to 3.0 mm. It was found that reducing the diameter of the impeller (from 236 mm to 162 mm) at a seed moisture content of 8.8 % improved the efficiency of dehulling. At a rotation frequency of the impeller of 2000 min–1, the highest total number of intact and destroyed kernels (23.23–29.33 %) was achieved for the two studied moistures. With an increase in seed moisture content from 8.8 % to 12.0 %, the number of dehulled kernels in the hempseed cake increased. It was noted that for seeds with a moisture content of 8.8 %, an increase in the gap led to a decrease in the dehulling efficiency for each of the three investigated seed fractions. The total number of dehulled kernels under such conditions decreased by 2.4–6.8 % and amounted to 16.4–26.9 %. For seeds with a moisture content of 12.0 %, an increase in the gap, on the contrary, increased the dehulling efficiency for each of the three investigated seed fractions. The total number of dehulled kernels for seeds of marked moisture increased within the range of 1.4–3.6 % and amounted to 27.4–31.0 %.
The influence of combine drive design parameters on corn grain harvesting efficiency
(2025) Khvostenko, D.; Горбенко, Олександр Вікторович; Gorbenko, O. V.
The article investigates the impact of design parameters of grain combine harvester drives on the productivity, efficiency, and quality of corn grain harvesting. Considering current requirements for agrotechnological processes, particular attention is paid to the type of power transmission, gear ratio, adaptability of control systems, and energy efficiency of the drives. The research was conducted under field test conditions using modified models of combine harvesters equipped with different types of drive systems: mechanical, hydraulic, and adaptive hydraulic. The conducted analysis proves that the design parameters of the drive system significantly influence the technical and operational performance during corn harvesting. Specifically, parameters such as transmission type, gear ratio, adaptability, and energy efficiency determine the operational stability, grain loss rate, fuel consumption, and the quality of grain cleaning. The study results showed that the most effective system is the adaptive hydraulic drive, which ensures productivity of 33.2 t/h, minimizes grain losses to 0.6%, and reduces specific fuel consumption to 1.5 L/t. Mathematical analysis revealed a high degree of correlation between productivity and grain losses, cleaning quality, and energy consumption, confirming the advisability of improving drives in the direction of flexible mode regulation. The scientific novelty of the work lies in identifying a quantitative relationship between the drive type and the combine's comprehensive efficiency indicators, justifying the implementation of adaptive hydraulic systems in harvesting machinery. The practical significance of the study lies in the possibility of applying the obtained results for modernizing the existing fleet of machines and developing new technical solutions aimed at increasing productivity and reducing energy consumption in the grain harvesting process. The obtained results can serve as a basis for improving the existing designs of grain harvesters and for developing new adaptive drive systems that meet energy-saving, reliability, and high-quality technological process requirements.

(CTE Workshop Proceedings, 2023-03-21) Kanivets, O. V.; Kanivets, I. M. ; Gorda, T.; Gorbenko, O. V. ; Kelemesh, A. O. ; Канівець, Олександр Васильович; Канівець, Ірина Михайлівна; Горбенко, Олександр Вікторович; Келемеш, Антон Олександрович
In modern conditions, the transition to distance learning has set new tasks for teachers, in particular, related to laboratory work. In these works, students not only study the structure and features of special equipment, but also acquire practical skills in working with the tool. The purpose of the article is to present our own experience of developing and using in the educational process a mobile application for teaching micrometer measurements during the relevant remote laboratory work in the disciplines "Interchangeability, Standardization and Technical Measurements" and "Physics". The literature analysis showed that ICT is widely used in the educational process in higher education, but computer programs and mobile applications are usually developed for secondary school disciplines, so there was a need to develop an information program for teaching students in distance learning, in particular during laboratory work. In order to teach students to work with a micrometer during distance learning, we have developed a mobile application. The process of developing the application included modeling the micrometer in the CAD system, creating training scenes in the Unity game engine and writing scripts to fully immerse students in the learning process. The mobile application developed by us consists of three parts: theoretical, educational and practical. In the theoretical part, students learn the structure and principles of working with a micrometer. The training part is developed in the form of a video lesson of working with the equipment. The practical part contains an electronic model of the micrometer and allows you to make measurements. Thus, during distance learning using the developed application, the percentage of qualitative success of students in laboratory work on the topic ``Measuring parts with a micrometer'' increased by 7.3\% compared to the same period of distance learning without the use of this application.

The current state of waste management in Poltava region is summarized in this article. In this article were determined places of accumulation and the influence of population size on the volumes of domestic solid wastes formation. Here also was analyzed dynamics of changes in the production of domestic solid wastes in rural areas and in cities. The morphological composition of domestic solid wastes was determined due to researches during 2017-2019. In the article was conducted comparative analysis of the data of changes in the percentage of components, which are part of domestic solid wastes depending on the time of year. It is determined that about 55% of the waste is the organic part of domestic solid wastes. Using certain technologies organic part of domestic solid wastes can be processed into valuable products. The technology of processing the organic component of domestic solid wastes into compost adapted to conditions of private farm households is offered in this article. Here are justified the design parameters of small-sized household chopper for compost production and are given technical conditions of machine usage the in conditions of private farm households. Here also was calculated economic feasibility of machine usage for three farm households for the purpose of processing the organic component of domestic solid wastes into compost. The costs for equipment, materials and inventory were about 2.835 thousand EUR. Costs for electricity, water, wages, etc. were 4.379 thousand EUR. The cost of production of one kilogram of compost was 0.093 EUR/kg. The payback period of the project is 9 months. The use of new developed equipment for the processing of organic component of domestic solid wastes makes it possible to reduce the ecological environmental impact to a considerable extent. In addition, the use of wastes as secondary resources makes it possible to obtain funds for private farm households.
