The testing of the tractor and its main elements is based on the method of partial accelerations, the basis of which is the solution of the inverse task of the dynamics: the acting forces are estimated from the acceleration. The method and means of measurement (developed in the L. Pogorilyy UkrNDIPVT Kharkiv branch) are effectively used in testing tractors and its main elements. The results of the study. The proposed express methods make it possible to reduce the time for testing and timely identify shortcomings in the operation of the systems being tested. The proposed express test method for the cylinder-piston group provides the ability to timely identify shortcomings in the operation of engines. It has been established that the most efficient operation of the tested unit is when the tractor is not fully loaded. The stability of the movement of the transport-technological unit is interconnected with its controllability, which is determined by the technical condition of the steering. The relationship between the investigated values of the angular accelerations of the steering wheel of the tractor and the aggregated machine is provided with a reliability of 95 %. To determine the braking properties, an indicator is proposed that characterizes the growth rate of the tractor deceleration during braking. To evaluate the quality of functioning of the hydraulic drive of the tractor mounted system in the case of unstable technical condition of its elements, it is necessary to start with the evaluation of the fluid flow in the hydraulic cylinder and end with the analysis of the flow in the bypass valve. Conclusions. Code 2 of the OECD normalizes the methodology for operational testing of agricultural tractors, on the basis of which in L. Pogorilyy UkrNDIPVT Kharkiv branch developed industry standards for assessing the traction and energy performance of tractors. It has been theoretically and experimentally proved that in the performance tests of tractors and its main elements, the method of partial accelerations is effective, which is based on the reverse transition from the vector sum in the space of forces that act on the tractor to the vector sum in the space of accelerations. This method allows you quickly assess the performance of tractors when coupled with mounted and trailed agricultural machines, as well as the technical condition of the main elements of the tractor design.

Research methods. Analytical research on the generalization of measures for biological protection of pigs, safety of pig farms and environmental protection was carried out by processing existing scientific reports, including EU regulatory requirements aimed at obtaining quality pig products. Research results. The procedure of biological protection of pigs is aimed at improving the physiological condition of animals and livestock productivity. During pork production, it is important to ensure the biological protection of animals to reduce the risk of spreading disease on pig farms. It is advisable to arrange a canopy on the playgrounds to protect pigs in bad weather and from the sun. With the intensification of pig farming, industrial practice shows an increase in the level of diseases of pigs associated with metabolic disorders in animals, the action of stressors, non-compliance with the parameters of the microclimate and feeding rules. In such conditions, preventive measures are especially important in the system of control of infectious and non-communicable diseases of pigs. Premises of pig farms after the completion of the technological cycle are subject to cleaning, keeping on sanitary rupture, ie the veterinary principle \"everything is busy - everything is empty\" must be observed. The safety of pig farms is a set of practical measures aimed at preventing the spread of infection to the farm and controlling the spread of infection within the farm. Biological safety of pig farms includes the following areas: biological isolation, biological regulation, biological protection. To protect the environment from pollution by pig farm waste, it is advisable to take the following measures. During the construction of pig farms it is necessary to observe sanitary gaps: to settlements not less than 1500 m, to other livestock facilities - 1000-1500 m. It is important to form a green belt, a strip of trees and shrubs around the pig farm - this is the most natural of all protective measures based on the fundamental principles of organic production.

Research methods. Analytical studies on the relevance of the use of energy culture of miscanthus as biomass for burning in solid fuel boilers were carried out by processing the available scientific and informational reports. Research results. For the production of biomass, special energy crops are used, which are characterized by rapid growth of technological mass - willow, poplar, sycamore, or certain varieties of herbaceous plants (miscanthus, millet, sorghum, etc.). Energy crops are plants that are specially grown for use directly as fuel or for biofuel production. After a single planting, the crop (miscanthus) can be harvested annually for 15 years or more with an average yield of 10 t/ha. Miscanthus has a well-developed root system (2,5 m deep), is characterized by rapid growth and resistance to low temperatures. Technological options for biomass combustion are divided into three main types: combustion in a layer, dust combustion, combustion in a pseudo-liquefied state, as well as a combined type - combined combustion of biomass with other fuels. Miscanthus is characterized by a fairly high level of energy production, and actually 143-560 GJ/ha, energy yield is 360 GJ/ha/year. Increasing the use of perennial energy crops such as miscanthus helps reduce fossil fuel consumption. In addition to high yields, drought resistance, maintaining soil structure, reducing the risk of soil erosion, improving soil organic matter and other important agronomic indicators, miscanthus has a high resource energy efficiency, which can be 90 %, a high level of conversion. With a yield of 8-17 t/ha/year, the selling price of miscanthus during its processing into thermal energy and biological oil of rapid pyrolysis was received at almost the same level - 100 €/t. The calorific value of energy culture is 17,7 MJ/kg, according to other scientific data is in the range of 16,0-17,2 MJ/kg, according to regulatory requirements CEN / TC 14961: 2005 – 18,4 MJ/kg, despite some deviations from the standards, miscanthus can be described as a valuable energy raw material suitable for combustion in boilers.

Methods. The field experiment was conducted in 2020/2021 on the lands of L. Pogorilyy UkrNDIPVT (Kyiv agro-soil district of the Right-Bank Forest-Steppe). Experience factors: factor A – tillage system (A1 – traditional, A2 – conservation, A3 – mulching, A4 – mini-till); Factor B – biological products \"Potassium Humate + Regoplant\" (B1 – control (without the use of preparations), B2 – the use of preparations for seed treatment and crop nutrition. When growing wheat, the traditional technology for the region was used, except for the elements of the experimental scheme. The effectiveness of the preparations was established by determining the biological yield of wheat and its structure compared to the control. Results. The use of humic preparations increased the weight of grain from the ear and the weight of 1000 seeds, which led to an increase in the biological yield of grain and the harvest index. The highest yield of wheat was observed in the traditional tillage system (A1), and the lowest – in the system of mini-till (A4). The largest increase in yield from the use of preparations (40 %) was observed in the version with a conservation tillage system (A2), and the smallest increase (20 %) – in the mulching tillage system version (A3). The experiment factors also influenced the growth of grain quality. In particular, the grain of the control variant contained 12.44 % of crude protein by weight of dry matter (seeds of the third class), and the grain of the experimental variant – 12.84 % of crude protein by weight of dry matter (seeds of the second class). There was also a decrease in the content of nitrogen-free extractive substances and crude ash. Conclusions. The use of \"Pop up Plants Humate Potassium\" and \"Regoplant\" had a positive effect on winter wheat yield and grain quality indicators. The average increase in the biological yield of winter wheat under different tillage systems was 30 % of the control.

Research methods: hypothesis, experiment, field observation, laboratory, visual and comparative calculation method. Research results. Research conducted in the conditions of the West of Ukraine. The experimental field was characterized by sod-podzolic light loam soils. During the studies, the effectiveness of foliar fertilization with water-soluble fertilizer Rosasol 18-18-18 + IU (3 kg/ha) and plant protection systems (spraying with insecticide August Borei Neo and fungicide Amistar Extra 280 SC) was determined. The experiments studied hybrids Ajax (FAO 210), Scanner (FAO 250), Exsklam (FAO 270) and Pioneer (FAO 300). For research, 12 sites with different foliar feeding schemes and plant protection systems were established. Mulching tillage was carried out at all sites. Urea (200 kg/ha) and magnesium sulfate (150 kg/ha) were applied for pre-sowing tillage. Sowing was performed with a Väderstad Tempo 8 seeder, which simultaneously with the sowing of seeds carried out intra-soil application of polyphos fertilizer (150 kg/ha). Seed sowing rate 15 kg/ha. To protect plants from weeds, crops were sprayed with Task Extra seed herbicide (0.44 l/ha). According to the results of research, it was found that foliar fertilization with Rosasol 18-18-18 + ME fertilizer contributed to the increase in corn grain yield by 0.78-1.65 t/ha. The highest yield was observed in the hybrid Pioneer (FAO 300), which was 11.68 t/ha (yield increase of 16.0 %), and the lowest in the hybrid Ajax (FAO 210) - 8.20 t/ha (yield increase of 18.0 %).

The aim of the research is to substantiate the analytical provisions of engineering management of the state of independent elements of plant engineering. The practical result will be the formation of the initial provisions of Smart-technology of engineering management to change the state of independent elements of plant engineering. Research methods. The methodological basis of the work is the generalization and analysis of known scientific results regarding the engineering management of the state of independent elements of plant engineering, and the use of a systems approach. Analytical method and comparative analysis was used to form a scientific problem, determine the purpose and set research objectives. The main provisions of the theory of systems engineering, methodology of systems analysis, theory of matrices, differential calculations and research on the theory of graphs, the theory of Markov processes, Bernoulli's theorem was used to create analytical models. The results of the study. The article considers the solutions that allowed substantiate the differential equations that characterize changes in the state of agricultural machinery in the complex of plant engineering, similar to which in the theory of Markov processes is called equations of reproduction and death. The analytical paper uses the ergodic property of Markov processes, according to which the existence of a limit or established regime of stationary probabilistic process of changing the state of agricultural machinery in the complex of plant engineering systems is established. The article considers the probability models of changes in the state of agricultural machinery in the aggregate of plant engineering systems, which tend to the limit values and do not depend on the initial distribution of . The solution of these models for the regime, we can find the probabilities of , where , of all possible states of agricultural machinery in the aggregate of plant engineering. This was used to determine the level of technical readiness of agricultural machinery. According to Bernoulli's theorem, it is established that with increasing number of experiments, namely state transitions in the analyzed case, the frequency of the event converges in probability with the probability of the event, and for the regime. Conclusions. As a result of research: - new scientifically sound technical and technological solutions and developments were obtained, which are aimed at substantiating the analytical provisions of engineering management of independent elements of plant engineering, which will serve as the starting point of Smart technology of engineering management. - it was confirmed that the intensity of recovery, in addition to the number of faulty agricultural machinery in the structure of crop production technologies, also depends on the nature of faults and the type of troubleshooting, and the type of engineering management tools. - the analytical provisions for deter","PeriodicalId":34711,"journal":{"name":"Tekhnikotekhnologichni aspekti rozvitku ta viprobuvannia novoyi tekhniki i tekhnologii dlia sil''s''kogo gospodarstva Ukrayini","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41881329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
