• W4385492731 abstract "Summary The purpose of research. Evaluation of the quantitative and qualitative parameters of the wear of the disc working bodies of the DL-2.5 soil tillage unit on the basis of monitoring their condition during tests in the conditions of experimental operation over a 6-year period and forecasting the possibility of further operation of the unit. Research methods. Analysis of the machine design, determination of the linear dimensions of discs by standardized measurement methods and statistical data processing. Research results. The intensity of the wear of the disk working bodies depending on the earnings, the forecast of the resource before the loss of quality is established. Conclusions. On the basis of experimental studies, objective and reliable information was obtained about the parameters of the wear of the disc working bodies of the DL-2.5 soil-cultivation unit in the conditions of economic operation in the forest-steppe zone of Ukraine. During the six-year period of testing, with a total volume of work performed by the unit of 2430.6 ha (2017 – 395,4 ha; 2018 – 413,3 ha; 2019 – 456,3 ha; 2020 – 357,6 ha; 2021 – 400,0 ha; 2022 – 408,0 ha) and the achievement of cultivation per disc - 120 ha, the wear of the working edge of the discs of the front and rear rows amounted to 21,1 mm and 11,5 mm, respectively, for the permissible value of 35 mm, or in percentages, respectively - 60,2 and 32,8. Accordingly, the estimated residual resource is forecast at the level of 39,8 % and 67,2 %. According to the results of resource tests during 2017-2022, the unit maintained its operable condition, provided the necessary regulation, aggregation, transportation and had an aesthetic appearance. The obtained results can be used by machine builders as an informative base for fine-tuning disks and forming standards for their performance, and by manufacturers of g. products, as information on the choice of reliable equipment and the potential of its service life. Prospects of research in this direction consist in the possible multiplicity of accounting for the general conditions of operation of disk tools, the variability of structural and technological schemes, and can also be used as methodical material for p. g. machines that have discs in their composition. Keywords: soil tillage unit; trial; disk working body; boring steel; wear and tear; projected resource." @default.
