ANALYSIS OF STEEL TYPE INFLUENCE ON THE STRESS AND SAFETY PARAMETERS FOR THE CONSTRUCTION OF EQUIPMENT FRAMES FITTED WITH CURVED PROFILE DIGGING SPADES

Abstract

To establish a new vegetable or cereal culture, a series of works must be carried out, the most important of which is plowing, also called the basic work of the soil, which, as it is carried out in the current technology, has many disadvantages, including the cost of the work, which implies a higher consumption of diesel and the negative effect on the structure of the soil, because the natural process of soil stabilization after plowing usually takes a few weeks. Under these conditions, within the framework of a project implemented under Measure 16: Cooperation, Submeasure 16.1: Support for the establishment and functioning of operational groups (GO), for the development of pilot projects, new products", an eco-innovative technology is promoted that performs the basic work of the soil in vegetable crops with a technical equipment provided with curved profiled plows. The construction of the curved profiled equipment frame was made from UNP (or "Universal NormalProfile"), INP (or "I NormalProfile"), L (or equal-wing angle) profiles following static analysis using SolidWorks software, with emphasis on von Mises stress and safety aspects analysis, for different grades of hot rolled steel: S235 / S275 / S355 according to EN10025. The analysis allowed us to better understand the 3D geometric model of the technical equipment frame's behavior depending on the demands it is subjected to and to verify the behavior of the chosen materials. The purpose of this work is to make available to specialists in the field, a quick tool for solving simple structural problems, without resorting to complex mathematical relationships that are characteristic of strength calculations.
