Item Пропускна спроможність і вантажопідйомність кузовних машин для внесення твердих органічних добрив(ЦНТУ, 2021) Лімонт, А. С.; Ломакін, В. О.; Лімонт, З. А.; Limont, A.; Lomakin, V.; Limont, Z.Мета дослідження полягала у визначенні і дослідженні пропускної спроможності кузовних машин для внесення твердих органічних добрив залежно від вантажопідйомності цих машин. Методика дослідження базувалася на використанні основних засад кореляційно-регресійного аналізу. Залежно від вантажопідйомності машин зміна їх пропускної спроможності описується рівнянням сповільнено зростаючої степеневої функції з визначеними коефіцієнтом кореляції і кореляційним відношенням пропускної спроможності машин на їх вантажопідйомність. Solid organic fertilization of soil proves one of the most important factors which contributes to increasing the yielding capacity of farm crops and improving their production qualities. Along with other means of mechanization body machines are used for the mechanized fertilization of soil through distributing fertilizers along the field surface. The paper is aimed at determining and investigating the carrying capacity of body machines used for applying solid organic fertilizers depending on their load-carrying capacity. The research technique lies in the comparative analysis of the determined resultative and factorial characters on the basis of the information obtained from the enterprises wlurh produce body machines. The information was chosen from the catologues of farm machinery and folders of the corresponding enterprises that produce tluse machines. The carrying capacity of machines was determined as the second-by-second advance of fertilizers in mass units (kilograms) to working parts of spreaders through the corresponding calculations; and the processing of harvesting and calculated data was carried out on the principles of the correlation and regression analysis, as wele as with the use of standard computer programs. The volume of statistical sampling amounted to 43 pairs of the investigated characters. The above has made it possible to estaflish. The positive correlation link between the carrying capacity of machines and their load-carrying capacity with the correlation coefficient amounting to 0.647 according to the correlation link of the resultative character on the factorial one, which equals 0.671. To ultimately determine the character of the relation between the investigated characters the authors accomplished the beveling of statistical data related to the carrying capacity of machines depending on their load-carrying capacity in the form of equations with straight line with positive angular coefficient and a number of curved lincar dependences. With iespeet to R2-coefficient the best correlation with experimental data was achieved through their approximation by means of equations of slow increasing step function. Of the investigated change is presented by the equation of the increasing hyperbola (R2=0.820), then according to the hyperbola asymptote with the load-carrying capacity increase of more than 20 tons their carrying capacity can amount to the marginal value of 25 kg/ses. The investigated dependences have to be taken into account when designing body machines used for applying solid organic fertilizers, as well as when using them for soil fertilization under the technological processes of mechanized growing of farm crops.
