Ergonomics is an element of a complex system of \"labor protection\" which is connected by intra-system connections with other elements of this system. In turn, ergonomics is a system for a number of relevant elements, the main of which are man and means of labor. The main task of labor protection (and, of course, ergonomics) is to ensure healthy and safe working conditions that minimize cases of occupational injuries and diseases. Research of human-machine systems is conducted in many directions with the use of modern methods. But we must also recognize that there are still many problems in this area of human life. This is eloquently evidenced by the statistics of occupational injuries (including fatal) in agriculture of Ukraine.\u0000The aim of the research is to reduce the number of occupational injuries and occupational diseases of agricultural workers by studying the ergonomic principles of the human-machine system, identifying its basic elements, relationships, possible reactions to external and internal disturbances and developing adequate solutions to reduce possible risks to the life and health of workers.\u0000The relationship between man and machine is one of the many types of relationships that work. There are four types of such dependencies: \"man-machine\", \"man-man\", \"machine-machine\", \"operation-operation\". In ergonomic research, it is often important to determine how a worker uses the controls in his workplace - how often he uses each of these organs and, most importantly, in what sequence.\u0000In order to facilitate the solution of this problem, the concept of \"communication\" is introduced. Information about the obtained connections is summarized with the help of special matrices.\u0000In addition to the interaction of man and machine in agriculture, it is necessary to take into account the specifics of the material environment and external conditions in the workplace.\u0000The analysis of the \"man-machine\" system should include not only technical aspects, but also take into account the specifics of the material environment and external conditions in the workplace, as well as organizational aspects that are revealed only in dynamic analysis of the system.","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125396919","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}

In the process of evaluation it was shown that the most significant component of methodological error occurs due to changes in temperature and frequency of the information wave. Temperature-dependent values included in the mathematical model of the band asymmetric humidity sensor are: relative dielectric constant of the substrate dielectric and the object of control, length and width of the central conductor, substrate dielectric thickness. The dielectric constant of the dielectric of the object of control depends on the frequency of the information wave, and this parameter is directly included in the coefficients of the sensor conversion equation. The results of the research showed that in the process of measuring the conversion of humidity in the band asymmetric sensor there is a methodological component of the error associated with changes in temperature and instability of the frequency of the information wave. To ensure a frequency error at a level not exceeding 0.5%, the error of instability of the frequency of the information wave when converting humidity into the output amplitude of the information wave should not exceed ± 3 kHz, provided by existing RF generators. It is advisable to remove the temperature component of the error using the method of correction. The mathematical model of band asymmetric measurement of moisture conversion of heterogeneous dispersed dielectrics in the high-frequency region was also improved.","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122967258","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}

The solution to this problem is possible through the use of powerful small-sized drives - namely hydraulic drives. These properties of the drive of this type have become crucial for its widespread use in agricultural machinery. Today, the hydraulic drive is used to drive the working bodies of machines, and as the drive of the main movement of self-propelled agricultural machines. The main hydraulic unit that drives a self-propelled agricultural machine is a hydrostatic transmission. Significant competition in the market of self-propelled agricultural machinery has led to an increase in the level of technical requirements for both agricultural machinery in general and hydrostatic transmissions operating in their composition. At the same time, further increase of energy saving and economic efficiency becomes especially important. The solution of the set tasks is greatly facilitated by further hydrofication of the drives and working bodies of agricultural machines. The most successful solution to this problem is the use of a hydrostatic drive, a typical representative of which are hydrostatic transmissions such as GST-90.\u0000The analysis of theoretical researches is carried out, the design of the stand for carrying out experimental researches for the purpose of confirmation of results of mathematical modeling is offered. Measuring and recording equipment for conducting a physical experiment is described. The coincidence of the results of experimental studies of hydrostatic transmissions with the results of computer simulation based on the developed mathematical model confirms its adequacy and correctness of the assumptions.

In most cases this waste is poured out in nearest reservoirs or on ground and that leads to environment pollution. But after separation from the waste of the liquid phase (waste dehydration) its hard phase can be used as a valuable additive to agricultural fodders or as a high calorie fuel. By article’s authors notion the most prospective method of separation of the damp dispersive waste is mechanical dehydration, that provides high productivity of the working process, low consumption of energy (in 240 – 800 times lower then under realization of thermal methods) and necessary final humidity of the waste (20 – 25% in case of utilization by a method of vibro-blowing dehydration). One of the most prospective types of equipment for mechanical separation of the damp dispersive waste are presses with hydraulic drive that have relatively compact dimensions, high energy efficiency and reliability and provide a possibility for wide-range and infinitely variable control of main parameters of a loading regime of the waste processing. There is a scheme of an improved and high effective installation with hydraulic drive for separation of damp dispersive materials is presented in the article. Besides there are elaborated equations of its mathematic model that connect working parameters of separation, design parameters of the installation and physical-mechanical characteristics of the processed material. These equations can be used for optimization of the installation’s design and for creation of its method of projecting calculation.","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133140970","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}

In the process of life, animals emit a large amount of heat, moisture, harmful gases, including carbon dioxide, ammonia and hydrogen sulfide. If the ventilation system does not work satisfactorily, the concentration of water vapor and harmful gases may exceed the standards, as a result of which animals drastically reduce productivity and may die. Currently, when creating livestock enterprises, it is necessary to resolve issues related to the reduction of investments, 40% of which is equipment. More than 20% of the cost of equipment falls on the heating and ventilation system; it is on it that they most often try to save money. Disagreements often arise between specialists on the deviation of microclimate parameters from optimal values for the productive qualities of farm animals.\u0000The article presents the physical and mathematical apparatus and methods for simulating the process of heat and mass transfer in an indirect-evaporative type heat exchanger for livestock buildings. The description of the process of heat and mass transfer in the heat exchanger of the indirect evaporative type of the Maisotsenko cycle is complex and requires the solution of many important mathematical problems (for example, the algorithmic solution of the combined heat and mass transfer on the surface with existing walls). Of particular importance is the development of an efficient algorithm that allows one to calculate differential equations of heat and mass transfer in partial derivatives. Therefore, the aim of the research is to describe the physical and mathematical apparatus and simulation technique (numerical simulation) of the heat and mass transfer process in an indirect evaporative type heat exchanger. As a result of analytical studies, the physico-mathematical apparatus of the process of heat and mass transfer in the heat exchanger of the indirect evaporative type of the Maisotsenko cycle was compiled, including the energy balance equation, taking into account sensitive and latent heat transfer on the surface of the wall of the wet and dry channels. The initial and limiting conditions of the heat and mass transfer model in the working part of the evaporative cooler under study are determined, which form the basis of numerical simulation in the Star CCM+ software package. A simulation technique (numerical modeling) has been developed and preliminary studies of the heat and mass transfer process in the heat exchanger of the indirect evaporative type of the Maysocenka cycle have been carried out. As a result of numerical simulation, the distributions of the temperature field, the vector field of velocities and the absolute humidity of the air flow in the heat exchanger of the indirect evaporative type of the Maysocenka cycle were obtained.","PeriodicalId":173336,"journal":{"name":"ENGINEERING, ENERGY, TRANSPORT AIC","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114406721","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}

It is noted that to obtain high-quality hay should be widely used technical means that accelerate the drying of grass in the field: conditioners, tedders, rakes, and for drying hay - ventilation systems with heated air. The basic measures, adjustment and preparation of mechanization means at mowing, flattening, agitation and harvesting of hay are substantiated.\u0000It is noted in the work that increasing the compression force of the rollers of the mower E-303 helps to accelerate the drying of the roller mass of the clover. It is established that the use of roller mower conditioner allows to get the weight for hay 2-3 days after mowing, which is less per day than mowing without weight conditioning.
