The designs of the working bodies of tillage and sowing machines are subject to requirements to ensure optimal agrotechnical requirements and minimize energy costs. This can be achieved by creating machines with controlled working bodies that are able to accurately comply with agrotechnical requirements and respond in a timely manner to changing external conditions. Known are designs of the working bodies of tillage machines, in which a flexible tubular element (manometric tubular spring) is used as a stand.
When applying variable pressure to the cavity of the tubular element, its end performs a reciprocating motion, which improves the quality of tillage. The paper presents the results of a study of the stress-strain state of the tubular element of the coulter using the ANSYS software package. The authors built a grid model of a tubular element, determined the horizontal component of the force of the soil impact on the coulter, at which stability loss is observed, and studied the influence of the geometric characteristics of the tubular element—the shape of the section, the opening angle, and the bending radius—on the critical force value. Tubular elements with a section variable in length were also investigated and their effectiveness was shown.
Key words: working body of a tillage machine / flexible tubular element / manometric tubular spring / vibration / stress / strain / ANSYS
