Abstract
The article presents the results of the calculation of stresses and strains of the structure of the Ripper rack, made in the form of a flexible tubular element, under loading by internal pressure and external force. The finite element method implemented in the ANSYS program was used for the research. The problems of constructing a grid model of a tubular element were solved, displacements of the free end and stresses under the action of internal pressure were determined, the maximum allowable pressure value was found. The horizontal component of the force of influence of the soil on the cultivator, in which there is a loss of stability, is determined. The soil resistance forces were determined by numerical methods depending on the shape of the paw and the speed of movement.
