Annotation

The parameters and modes of operation of the asymmetric disc harrow for soil cultivation were studied. During the determination of parameters and regimes, the theory of dimensions and similarity of physical quantities was applied. As a result of the study, regularities were revealed that reveal the relationship between parameters, operating modes and properties of the environment with energy indicators of the process. Experimental data on the operation of an asymmetric disc harrow with spherical discs for soil cultivation were used as initial data.
Based on the theory of dimensions, dependencies were obtained to determine the dimensions of the parameters and modes of operation of the disc harrow with spherical discs for soil cultivation and soil properties, such as traction resistance, depth, grip width, speed, soil hardness and acceleration. Similarity criteria were also determined on the basis of this theory.
With the help of correlation analysis and the method of least squares, the nature of the dependence and the corresponding coefficients were determined. A schedule was built to determine the operating modes and parameters of a disc harrow with spherical discs for soil cultivation.
To represent the dimension of each quantity that is included in the established formulas, in the form of a product of power functions of independent quantities (length L, time T and mass m), we can use the method of dimensional units.
On the basis of the obtained dependencies, it is possible to solve tasks related to determining the traction resistance of technical means for soil cultivation with disk harrows. Literary sources and well-known scientific studies in the field of soil cultivation with the technical means of a disk harrow were used as input data. Therefore, the conducted research made it possible to establish important relationships between the parameters and modes of operation of a disk harrow for soil cultivation using the theory of dimensions and similarity, which can be useful to improve agricultural production processes.

Keywords: theory of dimensions and similarity, soil treatment, parameters and regimes, hardness, tensile strength, criteria of similarity, relationship, validation of parameters and regimes.
