Introduction. The efficiency of separating long flax fiber from the flax straw largely depends on the structural parameters of the layer of flax stems. Modern fluffers for flax strips create random distortions and intersection of the layer of flax stems under the pick-up drum. These disadvantages of existing machines are minimized in an experimental fluffer, in which a layer of flax stems moves over the pick-up drum with a kinematic mode indicator equal to one. Aim of the Article. The study is aimed at finding means and methods for preserving the structural parameters of the layer of flax stems when fluffing flax straw strips. Materials and Methods. Experimental studies were carried out according to existing and newly developed methods, and the analysis of flax fiber was carried out according to the current GOST standards. The experiments were carried out on the flax strips formed by the LC-4A flax harvester. After grass sprouted through the strips of flax stems, they were fluffed with the serial machine VL-3 and an experimental fluffer. For each variant, the necessary measurements of the main structural parameters of the stem strip and collection of samples for analysis were made before the unit passed and after fluffering the flax stem strip. The results of measurements and processing of samples were processed using the methods of mathematical statistics. Results. It was found that macro-bends of the original and processed flax strips were in all the experiments. At the same time, the range of changes in the curvature of the flax strip outside the cutoff frequencies expanded 2.3 times under the influence of the working tools of the serial tedder VL-3. The randomness of these pulsations was caused by an increase in the distortion and elongation of the flax stems in the strip by 6.0° and 6.9%, respectively. At the same time, the experimental fluffer produced the smallest changes in the structural parameters of the flax stem layer. The technological evaluation of the flax straw confirmed the advantages of the experimental fluffer in comparison with the serial VL-3, which has an average production of long fiber higher by 0.65% and 0.5 units of number. Discussion and Conclusion. The analysis of the obtained results indicates the practicability of fluffing flax strips by picking up and moving the stems from above the pick-up drum with its kinematic mode index equal to one.

The problem of ensuring the necessary quality and exploitation of the properties of machine parts is becoming more and more important in mechanical engineering. The main idea of the work consists in the development of a fundamentally new approach to the monitoring of a machine tool complex of mechanical processing, the essence of which is the organization of the method of controlling the mechanical processing process on the basis of a single integrated information environment adapted to the universal complex of computer modeling Matlab/Stateflow and Matlab/Simulink, with structural representations of all components of the mechanical processing process and modeling as a problem-solving tool that expands the functionality of machine tool complexes. However, until now, generalized theoretical relationships between surface quality parameters, processing accuracy, operational properties of parts and parameters of mechanical processing processes, which allow solving the problem of technological support of given operational properties of parts. Management of the process of forming a surface with the necessary properties is carried out mainly by using partial experimental dependencies and tables of processing modes. The complexity of the problem lies in the fact that when processing parts, it is necessary to establish such processing conditions that would provide a set of requirements for tool wear, processing accuracy, surface quality characteristics, productivity, etc. The areas of the most effective use of production systems are primarily determined by the technological equipment that is a component of the system, the nomenclature of processed parts and the automated control system. which allow to solve the problem of technological provision of given operational properties of parts.

The need to solve the problem of reducing labor intensity, reducing the volume of earthworks, as well as reducing the time of the process of sinking piles in orchards and vineyards. Currently, the theoretical issues of the dynamics of piles when they are immersed in the soil have not been developed to the extent required by practice. The primary task here is to study the process of sinking the pile into the soil in order to achieve the required depth of immersion with minimal damage to the structure of the pile itself, and for it to perform the work that is set before it. Naturally, in the process of sinking piles into the soil, not only elastic, but also viscous, plastic properties of the soil are manifested and its destruction occurs. The theoretical tasks of sinking the pile into the soil, taking into account the viscous, plastic properties of the soil environment and the deformation characteristics of the pile material, have not been investigated. Nowadays, in connection with the circumstances that are currently happening in Krane, in the Vinnytsia region, the percentage of people's involvement in agricultural affairs is growing significantly, namely: in the planting of new garden and grape plantations and lands. There is a demand for immersion equipment that can quickly and efficiently perform the assigned tasks. Therefore, increasing the productivity of the process of sinking piles in orchards and vineyards through the use of hydrojet technology is an extremely relevant topic. The purpose of the article is to increase the productivity of the process of sinking piles in orchards and vineyards by using hydrojet technology. Creation of favorable conditions for the intensification of the production process and the application of effective methods of action on its object; continuous implementation of technological movement; reduction and general elimination of the use of unproductive labor; in particular, when performing auxiliary operations; management of the dynamic state of the system in which technological action takes place; the multifunctionality of the technological process and the harmonious combination of its main structural components are, for the most part, trends in the development of technical progress in the implementation of pile sinking.
