“…Nowadays, hammer crushers have become widely used on livestock farms and feed productions for grinding grain [3]. In these technological machines, the destruction of the material occurs in a consistent course of stages: applying a distributed load to the flat face of a hinged hammer, the emergence of various kinds of deformations in the body and the growth of stresses, the achievement of limit values of stresses and deformations, breaking of atomic and molecular bonds [2].…”

In the feed industry raw material, grinding is an integral part of the production cycle. However, this process is characterized by significant energy consumption – from 3 to 100 kW * hour per ton of finished goods, and only a part of it is directly spent on grinding. Therefore, this scientific research is aimed at minimizing the consumption of energy resources by technological machines – crushers and improving the energy efficiency of the process in general is an urgent issue. A powerful modern research method of studying complex objects is system analysis, which enables to modernize existing machines and design new ones without conducting a large number of expensive physical experiments. Unfortunately, this method is not yet widely used in the research and design of new machines for processing agricultural products, since there are no developed and substantiated engineering theories describing the behaviour of the processed material in the workspace of the technological machine. Grinding grain with a moisture content indicator at the level higher than the base condition, there is a low efficiency of the method of impact grinding, that is determined by the increased plasticity of the material and an increase in the value of the marginal deformation, which can lead the grain towards destruction. A partial solution of this problem is possible when combining the method of cutting and hammering, which has formed the basis of a technical solution implemented in the scientific laboratory of Vinnytsia National Agrarian University, where the design has been developed and experimental verification of the vibrating crusher have been carried out. Further improvement of the energy efficiency of the technological operation of grain grinding requires theoretical researches of the dynamics of the process, and determining the minimum amount of energy required for destruction. The article deals with the laws of solid mechanics and the use of rheological methods in researching disperse systems, it presents the values of absolute deformation and the work that is carried out during the destruction of maize grain under the influence of applied impact-cutting load in analytical and graphic form. Moreover, the results of this research help us to establish the marginal values of plastic and elastic absolute deformations occurring in the material, which is a prerequisite for the theoretical substantiation of the grinding law.

Across industries, the demand for the ability to analyze components in operation and make decisions on repair based on the data obtained is growing rapidly. There is the potential to ensure safer operations while saving the cost of unnecessary new parts. A quick and relatively inexpensive method is a 3D scanner - the device that can scan a real component and create an accurate 3D model. For stationary cases - inspecting parts or assemblies - these are already established methods. In contrast, measurement of vibrations and deformations in operation is still not widespread and for turbomachinery, it can be a new direction of development.

“…Given the significance of well-known scientific developments on the research of the problems of corn cultivation for grain, consideration of a comprehensive approach to assessing adaptive traits of hybrids, elements of the technology and features of starch accumulation in grain will enable to carry out qualitative assessment of the possibility of bioethanol production. Research of this issue is a relevant and decisive factor in the process of forming the most productive parameters of corn and has scientific and practical significance (Yanovych et al, 2017;Yanovych et al, 2018;Mazur et al, 2019;David et al, 2020;Du et al, 2020;Telekalo & Melnyk, 2020). According to the studies, agribiocenosis is the level of functional organization of biological and ecological systems involved in production, which unfolds all the mechanisms of variability and the process of natural selection, the systemic manifestation of which should be taken into account during the selection process (Simons et al, 2020).…”

The article presents the results of mathematical modeling based on the construction and use of various images of the object, process or system. The research involves the study of the dependence of the level of productivity and valuable farming traits of corn hybrids in the form of mathematical models. Field research was carried out during 2011-2017 on the experimental fields of the Department of Crop Production, Breeding and Bioenergy Crops of Vinnytsia National Agrarian University, at the state enterprise “Research Farm “Kordelivske” of the Institute of Potato Production of the National Academy of Agrarian Sciences of Ukraine under conditions of the right-bank Forest-Steppe in accordance with the guidelines provided in “Methodology of Field Experiments in Corn”. The use of computer technology, in particular, cluster analysis, from our point of view, allows us to approach the difficult task of improving the efficiency of the correct choice of hybrids and technologies to obtain the maximum level of bioethanol yield per unit area of maize hybrids. An ecological-genetic model of quantitative traits was used to study the phenotypic productivity of corn hybrids and to establish the influence on the formation of their traits. The construction of the model is based on the hierarchy of manifestation of productivity traits in ontogenesis and the correspondence of their manifestation in organogenesis. The model consists of three modules of traits including the resulting one and double-component that reflect phenotypic implementation of the genetic formula. The resulting traits are those that have environmentally stable correlation and the highest total impact on the final resulting trait, namely, the yield. According to the results of researches of mathematical models of the influence of weather conditions on the formation of phenotypic productivity of corn hybrids of different maturity groups, both general biological regularities and group differences of trait formation have been established. Thus, the analysis of the differences between the groups of early and mid-early corn hybrids, in general reveals that their growth and development are affected to a relative extent by the amount of effective temperatures, amount of precipitation and HTC. In fact, the maturity groups studied differ insufficiently, and the main differences can be observed only in the variability of the traits studied or the closeness of their relationships with each other. However, mid hybrids respond somewhat differently to environmental factors, which allows to develop the elements of adaptive cultivation technology for each maturity group. Based on the results of cluster analysis, cluster dendrograms were created using the odd-numbered group method with the determination of Euclidean distances.
