RESULTS OF DETERMINATION OF TECHNOLOGICAL PROPERTIES OF WHITE CABBAGE
Introduction. The authors present the results of experimental studies of the technological properties of cabbage heads, obtained on the basis of the application of both standard and original methods developed by the authors to determine these properties. The need for these studies is due to the fact that the calculation of the main structural and kinematic parameters of a cabbage-cutting machine is impossible without knowledge of these properties.Object. The object of research was white cabbage of two varieties, the most common in the households of the Volgograd region. This is a medium-ripened variety "Glory" and a late-ripening variety "Filibuster". Materials and methods. When developing a cabbage harvesting machine and determining its main design and kinematic parameters, it is necessary to know the technological parameters of the object with which its working bodies interact, that is, cabbage heads. These include the dimensional and mass characteristics, the coefficients of friction of the elements of the object (cabbage leaves, cabbage stalks, etc.), the resistance of the head to dynamic and static loads, the efforts of cutting the cabbage stalk, the moment of inertia of the head. The research results were processed using mathematical statistics methods and presented in the form of graphs. Results and conclusions: The conducted experimental studies made it possible to determine the main technological parameters of cabbage heads of two varieties, the most common in the farms of the Volgograd region. This is a medium-ripened variety "Glory" and a late-ripening variety "Filibuster". The research results are presented both in tabular and in the form of graphs. The obtained patterns of changes in these parameters allow us to calculate the optimal kinematic and structural parameters of the working bodies of the cabbage harvesting machine.
